How can we open any pre existing text file in python using open function?

I tried giving path of the text file as an argument in open function but it throws an error.

open(r'filename with complete path','r') Using r in front of filename/path, will consider the path in raw text and works.. without this, I also faced errors while opening file with full path..

with open("text_file.txt", "r") as f: print(f.read()) If you wish to write to the file, switch the "r" (read) to "w" (write)

First Set the directory of the file... And then execute with Open("file.txt",r+) #to both read and write
