9 Command Line Flags To Run Python Scripts More Flexibly

Commonly used Python command-line options.

When invoking a Python script, you can specify various options/flags. They are used to modify the behavior of the Python interpreter when it runs a script or module.

Here are 9 of the most commonly used options:

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐜: Run a single Python command. Useful for running simple one-liners or testing code snippets.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐢: Run the script as usual and enter the interactive mode instead of terminating the program. Useful for debugging as you can interact with objects created during the program.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐎: Ignore assert statements (This is alphabet ‘O’). Useful for optimizing code by removing debugging code.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐎𝐎: Ignore assert statements and discard docstrings. Useful for further optimizing code by removing documentation strings.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐖: Ignore all warnings. Useful for turning off warnings temporarily and focusing on development.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐦: Run a module as a script.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐯: Enter verbose mode. Useful for printing extra information during program execution.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐱: Skip the first line. Useful for removing shebang lines or other comments at the start of a script.

🔷 𝐩𝐲𝐭𝐡𝐨𝐧 -𝐄: ignore all Python environment variables. Useful for ensuring a consistent program behavior by ignoring environment variables that may affect program execution.
