Working With APIs in Python - Pagination and Data Extraction
HTML-код
- Опубликовано: 17 май 2024
- In this video I will show you how to work with an API using Python to extract data. Using the requests module
we can request the data in JSON format and then parse it out. Each response comes with some extra info too that
we can use to work out how many pages we need to request and the total amount of items we should expect to get.
Working with APIs in Python is a core skill for any developer so hopefully you can use this video as a good learning
resource and start requesting data from APIs in your own projects!

Thanks for linking this video John!
No worries hope it helped you!
@@JohnWatsonRooney It sure does!
Love you man, i saw like 10 videos about APIs request and data pull. All of them with over 1M viewers.. and they all just show how to code the request and not anything else, which is equal to nothing, what a waste of time. This video is simple, concrete, and right to the point. You surely deserve more viewers.
This should be the first video recommended when you search for making API requests. Went through the video quickly but will be watching slowly tomorrow while coding alongside the video :)
I have to say that you have given on your channel the most comprehensive insight in to scraping of any person on this platform. For that I must say a very big thank you.
Thank you very kind
Love the way you have started from scratch and have gradually paced up to the pagination part. Very short and crisp way of teaching, much appreciated! 🙌
Thank you, very kind!
love your way of teaching, straightforward with no fluff, thank you!
Thanks!
Best explanation I have ever heard. With your help I was able to figure it all out. thanks for what you do.
Extremely helpful. Cannot thank you enough for this.
I loved this thank you so much. Your explanations were perfect , detailed yet to the point!
i was able to do it, this is a great video!
lots of respect and love to you man!🌻
Hi John, great explanation!. The process is the the same when I have a page_token instead of a page number?. Thanks
Thanks John! I learned a lot with your video!
Awesome sir. Your way of teaching is so good.
What a great presentation, thnx John
I am just starting to learn Python programming and I can say that you are my best and favorite Teacher! Thank you!
Wow, thanks!
Best tutorial on this topic i found so far! Thanks man!
Thanks!
This is the best tutorial on APIs that I have watched. It's excellent!
Glad you think so!
Thank you John , very helpful
Great and informative video, thank you so much!
Awesome explanation! Thanks a ton.
Hello, thank you for the video.
I wanted to ask what extension/program you are using to make the API's more readable in your browser. Thank you
I learned a lot. Thank you very much!
This was a very helpful walk-through - Thanks for the great content! :)
Thanks for watching!
Nice one John! Love working with an API me. This is great :)
Thank you!
Fantastic, very good explain it. You got a new subscriber
i had some confusion about API's but you just made it look very simple
Thank you, I will make this as my reference :)
learing about api's and found your video. great project! easy to follow along and replicate. thank you!
nice well structured video.
tremendous experience I 've completed this tutorial & clear crystal for each topics ,thank you for taking much more efforts
Glad it was helpful!
Really neat an well structured Video and Code! Thank you kind Sir!
Glad it was helpful!
Great Video and an awesome teaching. But what if your api allows you to make asynchronous call? How should we handle pagination in such cases?
Useful tutorial. Thanks.
This video is very informative
I have a question. When you are using a list for organizing data into pandas, how do you specify an area that is below episodes?
Thank you for your video.
Thank you for this video, It is very help as it solves most of the challenges with my use case.
The only challenge is that, I needed to save the raw JSON data I to the data.
How d you suggest I go about it?
Wonderful tutorial ever : ) thanks
ok thanks again for your video. Now I am getting a better idea of scraping through api.
very nicely put together; I have been working api's using python and this video helps.
One thing I always been trying/looking for is that, is there a way to create a generic python project to handle any api rest calls? I am aware that each api is customized by the api provider but just still trying to come up with something generic. Any thoughts/suggestions on this lines?
great video!!
Simple and superb!!!
Thanks
Thanks a lot for this video John 😀
Thanks for watching!
Great video John, very helpful and thanks for sharing.
Maybe one suggestion to think over .
The little pip of your face is in de right hand down corner.
But most of the output of the terminal is also down under so (and I have noticed in many of your video's) the output is often hidden behind that small screen.
Maybe it would be better to put it (the PIP) in the top righthand corner.
Anyways, thanks for the effort of making these video's.
In the past I had to search in YT for solutions for my questions but now since I found your channel, all the(my) answers are here in one channel.
Good suggestion thank you, I will check goign forward not to block the terminal output and move my camera picture if needed!
Thanks.This is great :)
Like your video! Thanks
Thank you for a great presentation
Thanks!
Very important subject in web scraping. Need more tutorials on it if possible. Thanks for adding value.💖👌🌹
Love ur stuff John, keep going. ATM dealing with an api that needs a bearer token, that changes daily. Am stumped ATM, need to figure that out otherwise I cant print price no more 😪
awesome tutorial sir
great video, thank you
Well done sir
Where does 'response' come from in the second function that was created?
watched this video because of learning english :) thank you for clenan english
Thanks a lot
great video thnks!!!
What browser are you using that shows the number items in results? I tried Brave (based on Chromium) with a prettier JSON extension, and even Firefox, but when I collapse results, I don't see the number of items. TIA!
Thanks 👍
I wish I had watched this video before, it sure would've had helped me. The other two videos about API that you did, it was helpful to, but they were too short. I like long videos where you explain everything details by details.
Great, I’m glad this one was able to help you, thanks for watching
Hi John: I love your channel !!!! Fantastic! Keep it up!
I have one question:
in minute 11 when you are building def get_pages(response):
instead of pages = data ['info']['pages'] you put pages =response ['info']['pages'] .
You replace data with response.
My question : response = to what ?
You mean: response = r .json ?
why?
thankyou for your help!
The "response" is the json data that i am taking from the first function and passing into the second one. This function just parses the data, so we need to give it that data
@@JohnWatsonRooney Thanks John for your quick reply. I understand your explanation. And now I see that here response = main_request(baseurl, endpoint).
I am a complete beginner here. Just to understand what you did in laymans term. You basically mirrored the website into python and extracted information from it. Is this correct? And somehow, you also made the data in JSON format for ease of interpretation by Python.
always support with full view, like your video as a thanks to your teaching. Looking forward for your sharing more in SQL and APIs :)
Thank you!
Amazing!!!
Thanks!
wow nice content exactly i am looking same nice explanation
Thanks!
I get an error for the last for loop and using the 'mainlist'
TypeError: 'NoneType' object is not iterable.
I don't really understand why I'm getting that, I followed everything the same and it all worked up until the last part.
What is your career advice John?
good content good style i sub'd thanks John
Thanks glad you like it 👍
@@JohnWatsonRooney Hey John since you are online may I make a request? Can you do something with a rest api and specifically querystringparameters? Like GET requests with 3 or 4 parameters? I have not seen a good tutorial online on the topic.
Hai John, I need the data scraping form tha Google results with number of results and multi threading concept. If you make a video for this. It's will helpful for me
Awesome!! What if for each api call you get only 1000 records with 100 records per page and you need to get 20k records from your api in total. How to handle such cases?
John, would you know where I can find information on calling two APIs at once and using that data with Python?
Also, thanks for this video
hey thanks. if you wanted to call 2 different API's you can do it the same way from the same script, just change the URL
Thanks @@JohnWatsonRooney . I just want to be clear on this. If my transaction data api has customerID (int) and my customer data has customerID and I want to pull the transactions and include the customer name, not ID, I would use two URLs. Would I then have if tdata['customerID'] = cdata['customerID'] print cdata['customername']?
20:07 I had a problem with pandas being unrecognized, but i fixed it by using pip3 install pandas
instead of
pip install pandas
Hope this helps!
Suggest a way to return 2 million records from a paginated API when the limit is set to 10k records. What should be the approach using python?
Thanks. Is it possible to share python file.
corrigi a 3 para isto (para incluir math. e statistics.). Só que agora dá um erro a dizer: "'float' object is not iterable"
import math
import statistics
def normalization(list):
newList = []
if len(list)
def parse_json(response):
return [{'Name':item['name'],'No_Episodes':len(item['episode'])} for item in response['results']]
we could have used dict/list comprehension
2)
def custom_operator(numbers):
length = len(numbers)
output = [2 * numbers[0]] # Double the first number
if length > 2:
for i in range(1, length - 1):
result = sum(numbers[:i] + numbers[i+1:]) * numbers[i]
output.append(result)
output.append(2 * numbers[-1]) # Double the last number
return output
Hi sir u do with some external file like csv or excel file sir n read from excel and write back to that excel or csv file sir
Use pandas. You're welcome!
What are you using that your API is so much more readable? When I click on the link, I get a continuous line of text, not an organized block of text divided into different categories.
I’m the browser? Firefox does it by default- or the app I use is called insomnia to make api requests
@@JohnWatsonRooney I'll check those out, thanks John!

def create_dictionary_from_csv(filename, separator):
with open(filename, 'r') as file:
lines = file.readlines()
keys = lines[0].strip().split(separator)
dictionary = {}
for key in keys:
dictionary[key] = []
for line in lines[1:]:
values = line.strip().split(separator)
for i in range(len(keys)):
dictionary[keys[i]].append(values[i])
return dictionary
Which theme he is using please tell me
I'm pretty sure its Gruvbox Material
any links to the code
Example, in the API End point preview shows {"id":1, "displineID":2}, {"id":2, "displineID":1}, {"id":3, "displineID":3}, {"id":4, "displineID":1}, {"id":5, "displineID":2}
I want to find
1. Get id numbers of the "displineID": 2 only
2. Get id number of the first "displineID": 2 only
3. Get id number of the second "displineID": 2 only
How can I write this in Python? If you have a video or coding relate to this, would you share the link please?
