How to Copy Contents of One File into Another in Python


In this example, we will learn how to copy the contents of one file and write it to another file. In Python, it can be processed through the method of looping statements to write the contents of the source file to the output file line by row.

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

sourceFile = input("Please input the input file name: ")
outFile = input("Please input the output file name: ")
with open(sourceFile, 'r') as file1:
    with open(outFile, 'w') as file2:
        for line in file1:
            file2.write(line)
