3 years later and this is DIAMONDS. I would be baffled if your students havent succeeded in life
Cheers - I'm glad you liked it! Keep on codin'!
Thank you! This has helped me get an idea so I can start my project.
You are quite welcome - glad I could help!
Nice!
Thanks!
@@TokyoEdTech :)
this was so helpful thanks Tokyo
Glad you liked it - one of my better more informative lessons!
what would you do for a longer file?
For larger amounts of data I'd go with a database.
how do you still do that if you have a header on the csv file?
Skip the first row.
@@TokyoEdTech how do you skip the first row? I tried next but it doesn’t work
@@joaogodinho2029 I don't remember the exact code I used. But at some point there is a list with the data in it - after splitting. So iterate from index 1 instead of 0.
I love you
Thanks - I think!
how do I make it where a person inputs a name from the csv file and it counts how many times that name is in the file?
Which part are you having trouble with?
I too had the same question
Using your example above, if I wanted to find out how many names were in the dictionary, how would I impliment that into my code?
@@TokyoEdTech I followed all the steps and i created a dictionary named tree_list, what i'm trying to do with tree_list
• When the program runs the user will have a command prompt to enter a tree name, like this, Enter the tree name:
• The user will enter the name of a tree such as Cedar and hit return, the program will look through a row I created called spc_common = info[3]
• The program will look to see if the name Cedar is in that specific row and will return the number of Cedar trees in the row called spc_common = into[3] and return a number
For example:
You entered: Cedar
Total number of trees: 20
Zip codes this tree is found in: 10010, 10000, 11550
Towns containing the largest number: Chelsea, Nolita, Soho
When the code is finished I need it to print the information above.
I have also created rows for the zip codes called zipcode = info[4], cityname = info[5], so in total I have 8 rows going from [0] to [8].
I see you created a dictionary inside of a dictionary but it just prints your 3 rows name, birth year and role when you enter.
@@aidandiaz3192 I don't know, I replied to you by accident. I deleted it and sent the question to TokyoEdtech
