Three ways to run Python:1, interactive interpreter:

The command-line window enters Python and starts writing Python code in the interactive interpreter.
Python coding can also be done in Unix,dos or any other system that provides a command line or shell.

$python # unix/linux# or python% # Unix/linux

The following are the Python command-line parameters:

• -D displays debug information at parse time
• -O Generate Optimization code (. pyo file)
• -S does not introduce a location to find Python paths when booting
• -V Output Python version number
• -X is obsolete based on the built-in exception (for strings only) since version 1.6.
• -C CMD executes the Python script and runs the result as a CMD string.

File executes the Python script in the given Python file.

2. Command line script

In your application, you can execute a python script on the command line by introducing an interpreter, as follows:

$python script.py # unix/linux# or python% script.py # Unix/linux

Note: When executing a script, check to see if the script has executable permissions.

3. IDE for integrated development environment
