How Can I Redirect Python\'s stdout Output to a String Variable?

Redirecting stdout Output to a String Buffer in Python

When using ftplib in Python, some functions output information to stdout instead of returning strings. If you require this output in a string variable, redirection is necessary.

To redirect stdout to an in-memory buffer, consider the following solution:

from cStringIO import StringIO  # Python 2
# or from io import StringIO  # Python 3

import sys

# Save the original stdout object
old_stdout = sys.stdout

# Create a new StringIO object to capture stdout output
mystdout = StringIO()

# Redirect stdout to the new StringIO object
sys.stdout = mystdout

# Execute code that generates stdout output
# ...

# Restore original stdout
sys.stdout = old_stdout

# Access the captured stdout output
output = mystdout.getvalue()

This method effectively wraps a StringIO buffer around stdout, allowing you to capture and manipulate the output as a string after execution.
