Python, writing an integer to a '.txt' file

Question

Would using the pickle function be the fastest and most robust way to write an integer to a text file?

Here is the syntax I have so far:

import pickle

p         


        

Answer 1

The following opens a while and appends the following number to it.

def writeNums(*args):
with open('f.txt','a') as f:
    f.write('\n'.join([str(n) for n in args])+'\n')

writeNums(input("Enter a numer:"))
