Editing Standard streams (section)

===2000 - : Python (2 or 3) ===
The following example, written in [[Python (programming language)|Python]], shows how to redirect the standard input both to the standard output
and to a text file.

<syntaxhighlight lang="python" line="1">
#!/usr/bin/env python
import sys
# Save the current stdout so that we can revert sys.stdout
# after we complete our redirection
stdin_fileno = sys.stdin
stdout_fileno = sys.stdout
# Redirect sys.stdout to the file
sys.stdout = open("myfile.txt", "w")
ctr = 0
for inps in stdin_fileno:
    ctrs = str(ctr)
    # Prints to the redirected stdout ()
    sys.stdout.write(ctrs + ") this is to the redirected --->" + inps + "\n")
    # Prints to the actual saved stdout handler
    stdout_fileno.write(ctrs + ") this is to the actual  --->" + inps + "\n")
    ctr = ctr + 1
# Close the file
sys.stdout.close()
# Restore sys.stdout to our old saved file handler
sys.stdout = stdout_fileno
