Python Program to Copy One File to Another File

This is a Python Program to copy the contents of one file into another.

The program copies the contents of one file and writes it into another.

1. Open one file called test.txt in read mode.
2. Open another file out.txt in write mode.
3. Read each line from the input file and write it into the output file.
4. Exit.

Here is source code of the Python Program to copy the contents of one file into another. The program output is also shown below.

with open("test.txt") as f:
    with open("out.txt", "w") as f1:
        for line in f:
            f1.write(line)

1. The file test.txt is opened using the open() function using the f stream.
2. Another file out.txt is opened using the open() function in the write mode using the f1 stream.
3. Each line in the file is iterated over using a for loop (in the input stream).
4. Each of the iterated lines is written into the output file.

 
Case 1:
Contents of file(test.txt): 
Hello world
 
Output(out.text): 
Hello world
 
Case 2:
Contents of file(test.txt): 
Sanfoundry
 
Output(out.text): 
Sanfoundry
