With high regards...,💚
Mam your videos🖥 have helped me a lot for my 12th boards...your all concepts has grown my interest in computing😇
Mam only one doubt...why r u using the word object like reader & writer object...what's the meaning of object here?
Thank you mam💓💛
Thanks for appreciation...
writer()
This function in csv module returns a writer object that converts data into a delimited string and stores in a file object.
reader()
this function returns a reader object which returns an iterator of lines in the csv file. Using the regular for loop, all lines in the file are displayed
@@SwatiChawlaofficial
Thank u mam 😊for taking out your precious time to answer me...🙏
But still i am confused by the word 'object' you have used.😇
Pls guide me.
Generally..the variables of a class are known as objects...but since u don't have the concept of classes jn your course..u can consider it as a variable
@@SwatiChawlaofficial
Thanks for your guidance mam..🙏😇
Please upload a video on tabulate module or prettytable module that will help with CSV files also.
Yes..
Check out this..
ruclips.net/video/QjIqYbiVQuw/видео.html
In the beginning.. tabulate module is explained
Thanku Ma'am for crystal clear concept 🙏🏻
Most welcome 😊
Mam what does
mean? (Mam, I know
[it takes the pointer to next line just below])
means carriage return..
takes the cursor to the beginning of the line. It is the same effect as in a physical typewriter when you move your carriage to the beginning and overwrite whatever is there.
Mam I am pursuing mtech from IIT-MANDI.
Still useful your file handing....... Lecture
Glad to hear this...
Thanku so much...
God bless you..

Aur likha aa rha h CSV has no attribute writer.
Aisa kyu ho rha h plzz tell ma'am 🙏🏻🙏🏻🙏🏻🙏🏻
I think..u might have saved your Python file with name csv...
As csv is already a module, it wil search the writer ( )in your file now..
If this is the case, rename that file.. (don't do save as)
Either delete that file or rename that file..
Mam EOL chaeacter used in different operting system is in our syllabus 2024 exam plz plz plz reply mam

Thank you so much ma'am 🥰.Please upload a video even for append and search in csv files🙇♀️🙇♀️
actually that's not in the curriculum, that's y not uploaded..
@@SwatiChawlaofficial ok mam , thank you 😃
Ma'am i can't understand what is the function of csv. Writer
The csv module implements classes to read and write tabular data in CSV format. It allows programmers to say, “write this data in the format preferred by Excel,” or “read data from this file which was generated by Excel,” without knowing the precise details of the CSV format used by Excel.
mam i have an doubt ... i m facing an error in every file of data handling.. the error is name error whenever i tries to enter from the user alphabets the programs shows an error ... mean the same as u told the above code i wrote it same then . in output firstly i entered roll no. after that it ask the name then i entered then it shows error that name is not defined .. or if i write any number there then it proceed ahead and ask marks .. so i solved this problem can u help me.. basically i m facing same problem in every files which i read in this chapter the same code run in my frds pc but not in mine pc... what shout i do to solve this problem..
Check the location of your text file , binary file or csv file...and .py file..
It must be same.
If it is not stored on same location, specify absolute path
Thank you so much mam
Most welcome 😊
Ma'am iss video mai CSV fully explained hai ?
File Handling: ruclips.net/p/PL5Raijva2y4SoxE5BDz6tNkJivlSPYvDJ
Ma'am when i'm using newline then this error keeps coming...can you please guide me please
It will be really helpful for my exam on monday
f=open("Student.csv","w" ,newline=' ' )
ValueError: illegal newline value:
Thank you :)
In how many videos ..the CSV file is completed?
mam.. is csv file in our syllabus of 2021?
Yes
Nice explanation ma'am
Thank you 😃
I am unable to understand the difference between writerow and writerows. Can you please tell me the difference..
writerow() is used to write single row.
writerows() is used to write multiple rows.
Good evening mam
Mam i have one problem
I have written same code
Excel file also created but blank excel file is there nothing stored in excel sheet
if possible share ur code
Mam is there different methods for reading the data in file
Very nicely explained ma'am
Thanks 🙏🏻😊
But same program not executed in version 2.7 open( ) not supported newline=' ' . what is the reason...
Use latest version of python
Mam can we take csv module in capital letters??
Thank ma'am
Welcome...🙏🏻😊
maam, the s_writer.writerow part.....is compulsory for the statement inside the bracket to be a list or can it be a string as well?
Generally we used to enter pass the argument as List in writerow() . However, if you will pass in the form of tuple..it will convert it into list..
But in the form of string it will not accept..
@@SwatiChawlaofficial ok maam, thank you so much
What is meaning of delimited string ?
when i am importing csv module it's giving me an error that partially initialized module 'csv' can you tell me why?
I think you have saved your file with name csv.
Kindly delete it and create new
Excuse me Maam newline is not working with 3.8 version as newline=' ' it gives error
It will work..
in newline argument...within quotes no blank space is there...
It's empty string..
plz check ur code.
Mam in today live session you said to write the CSV in small word csv but the answer of that was capital CSV
Plz clear my doudt
if u r writing csv module..then it must be in small alphabets..
Answer was also in small letters..may be because of font size it was looking like capital..
In case of extension as csv...both capital and small will work..
Hope it's clear now..
Crystal clear concept
That's Great...
Keep watching...
awesome mam
Thanku
mam hum csv file open karne ke liye 'with open' ka use kar sakte h
Yes
Thanks a lot mam
Mam in writerow and writerrows rows were printed same only
yes
Hello mam
I m trying to run your code but there is 1 error at the start with open() csv file . Error is type error: an integer is required
Plz check your syntax carefully...
Or Enter integer value..
Or u can share your code here also
If I want to extract only roll no from student.csv using readline() what is the code for that?
Super Explanation 😃😂
Thanku...🙏🏻😊
Mam I executed this code in python but it is showing error ..
"Module csv has no attribute writer..
Plz tell me the problem
I think..u have saved ur file with name csv..
If this is the case..rename that file or delete the previous one and create the new one..
Thanks

Thanku mam
Welcome beta...😊🙏🏻
how to do with "with open"???
Madam if my data contains address which may contain coma. How to deal in case of csv
Comma is a default delimiter in csv..
We can select any other symbol also as a delimiter
@@SwatiChawlaofficial can it be seleted from character map. Thank you. With best regards. Your over aged Student
And mam why we took newline as empty? I didn't got the logic clearly...
Today's live session is on this topic....
DO attend the session..to clear ur doubts...
@@SwatiChawlaofficial okay mam
hi mam gd evng
mam on my laptop this csv one program is not working
one error is there after entering rolno:1 traceback (most recent call last)
value rror invalid literal for int()with base 10
plz tell solution
The Python ValueError: invalid literal for int() with base 10 error is raised when you try to convert a string value that is not formatted as an integer. ... Then, you can use int() to convert your number to an integer. If this does not work, make sure that the value of a string does not contain any letters.
mam this error solved one more error is there _csv.error ,iterable expected not int in this line. s_writer.writerow(1)
solution plz
and excel file generated but data is not there in excel file .blank excel file is there
@@SwatiChawlaofficial thanks mam
ho gyea mam thanks . problem solved
Thankyou so much ma'am.
But I just wants to know that views are so much but why only 700 likes?Please like the video also it hardly takes a second.
Yes... Thanks for your support..
The typing sounds ⌨️ 🥺😂🔥
Sorry for the inconvenience caused...
@@SwatiChawlaofficial mam I like that y r u asking sorry 😔❤️🤦♂️
Maam pls attach the pdf plss
Mam aap please mere school mai aa jao plz waise 5months hi hai but still.... Please ❤❤❤
🙂
Write row and write rows are working same
No
Ma'am delimeter means??
A CSV file stores data in rows and the values in each row is separated with a separator, also known as a delimiter. Although the file is defined as Comma Separated Values, the delimiter could be anything. The most common delimiters are: a comma (,), a semicolon (;), a tab (\t), a space ( ) and a pipe (|).
Mam. Can u plz tell about line_num method.?
csvreader.line_num is nothing but a counter which returns the number of rows which have been iterated.
@@SwatiChawlaofficial thankyou..!mam
Your videos are very helpful.. ♥️👌
Thanku...

#Neha ,nisha ,swati ,sonia always rocks 🤣🤣

mam app ek baar path bta dijye kaise kya hua
