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.
The above is the detailed content of How Can I Redirect Python\'s stdout Output to a String Variable?. For more information, please follow other related articles on the PHP Chinese website!
