The command python -c "${expression}" is used to execute a Python expression directly from the command line interface.

Here's the breakdown of the command:

• python: This is the command to run the Python interpreter.
• -c: It is a flag that tells the Python interpreter to execute the code directly from the command line.
• "${expression}": This part is a placeholder for the Python expression that you want to execute. The expression should be enclosed in double quotes.

When you run this command, the Python interpreter will be invoked, and it will evaluate and execute the provided expression. The result of the expression, if any, will be displayed on the command line.

For example, if you have the following expression: print("Hello, World!"), you could run it using the command python -c "print('Hello, World!')". The Python interpreter will execute the code and print the desired output on the terminal: Hello, World!.
