Opening a file - amitsinbox - Apr-12-2020

when I am trying to open a file in pthton 3 jupytor notebook, I get following error: what wrong am I doing?

file1=open("\C:\Users\Amit Kumar\Desktop\CSAT.txt","w")
Error:
File "<ipython-input-7-6ad445b74704>", line 1
    file1=open("\C:\Users\Amit Kumar\Desktop\CSAT.txt","w")
              ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 3-4: truncated \UXXXXXXXX escape

Don't use backslash in windows paths. Some combinations are escape sequences like \u

use a raw string, e.g. r"C:\Users\Amit Kumar\Desktop\CSAT.txt"
or forward slash, e.g. "C:/Users/Amit Kumar/Desktop/CSAT.txt"

note that I also removed the backslash at the start

It didnt help. I want to use Open Function to open the file. because for further commands it doesnt identify the file.

Show your code and how it didn't help. You need to replace your string "\C:\Users\Amit Kumar\Desktop\CSAT.txt" with one of mine...

RE: Opening a file - buran - Apr-13-2020

Your txt file is not in the current working directory (I see it's on the Desktop), so you need to pass full path:
with open(r"C:\Users\Amit Kumar\Desktop\CSAT.txt", "r") as f:
    file_stuff=f.read()
    print(file_stuff)
with open(r"C:\Users\Amit Kumar\Desktop\CSAT.txt", "r") as File2:
    for line in f:
        print(line)
