Create a file if it doesn't exist

Question

I\'m trying to open a file, and if the file doesn\'t exist, I need to create it and open it for writing. I have this so far:

#open file for reading
fn = input(\"         


        

Answer 1

Using input() implies Python 3, recent Python 3 versions have made the IOError exception deprecated (it is now an alias for OSError). So assuming you are using Python 3.3 or later:

fn = input('Enter file name: ')
try:
    file = open(fn, 'r')
except FileNotFoundError:
    file = open(fn, 'w')
