How to save code and run it in python

Python is a scripting language that uses text files (with a .py extension) to save code. There are two ways to run the code: enter exec(open("file path").read()) in the interactive interpreter; or enter the python file path in the command prompt. Make sure Python is added to the system path.

How to save and run code using Python

Python is a scripting language, which means that its code Typically not executed as a compiled format, but rather interpreted and executed directly by the interpreter. This makes the process of saving and running Python code very simple.

Saving Code

To save your Python code, simply create a text file and use .py as the file extension. For example, the file hello.py has the following content:

<code class="python">print("Hello, world!")</code>

Running Code

There are two main ways to run Python code:

• In the interactive interpreter: Open a command prompt or terminal and enter the following command:

<code>python</code>

This will start the Python interactive interpreter. You can then run the code by typing:

<code>>>> exec(open("hello.py").read())</code>

• As a script: This method is for those who want to run Python without entering an interactive interpreter code situation. In a command prompt or terminal, enter the following command:

<code>python hello.py</code>

This will run the hello.py file directly using the Python interpreter.

Note:

• Make sure you have added Python to your system path so you can run Python scripts in any directory.
• If your code contains relative paths, such as import my_module, make sure the my_module.py file is in the same directory as your main script.
• If your code requires additional libraries or modules, you need to install them using a package manager such as pip or conda.
