This example simply shows us how to save input into a file with Python.
2.Codes
#! /usr/bin/env python3
# -*- coding: utf-8 -*-
import sys
filename = input('Input file name:\n')
fp = open(filename, "w")
ch = input('Input a string:\n')
while ch != '%':
fp.write(ch + '\n')
sys.stdout.write(ch + '\n')
ch = input('')
fp.close()
When running the codes, you need the first input file name and the string to save. After that, you can see the content exists when you open the file.
