Save Python Terminal Output to a Text File in Python
Below are some of the ways by which we can save Python terminal output to a text file in Python:
Using the >
Operator in the Terminal
The >
operator is used in the terminal to redirect the standard output to a file. This approach is simple and effective for quickly saving the output.
Python3
for i in range ( 10 ): print ( "printing line " , i) |
Command
python script.py > output.txt
Output:
Using the tee Command
The tee
command is used to redirect output to both the terminal and a file. This approach is useful for real-time monitoring in the terminal while saving the output to a file.
Python3
for i in range ( 10 ): print ( "printing line " , i) |
Command
python script.py | tee output.txt
Output:
Redirecting sys.stdout in the Python Script
The sys.stdout
stream is redirected to a file using the with open(...)
block. This approach allows programmatically controlling where the output goes within the script.
Python3
import sys # Save the original stdout original_stdout = sys.stdout # Redirect stdout to a file with open ( 'output.txt' , 'w' ) as f: sys.stdout = f for i in range ( 10 ): print ( "printing line " , i) |
Output:
Using the logging Module
The logging
module is used to configure a log file. This approach is beneficial for more extensive projects where logging is a standard practice.
Python3
import logging # Configure logging to save to a file logging.basicConfig(filename = 'output.log' , level = logging.INFO) for i in range ( 10 ): logging.info( "printing line %d" , i) |
Output:
