Although PyCharm usually runs the main function as the entry point of the program, it also allows other functions to be called explicitly by calling them at the beginning of the module.
Why PyCharm can only run main
PyCharm does not only run the main function. It can also run other functions, as long as they are called explicitly at the beginning of the module.
main function
The main function is the entry point of a Python program. When you run a script or project, the Python interpreter automatically finds and runs the main function. If the main function is not provided, the interpreter will not execute any code.
Explicitly calling other functions
If you want PyCharm to run other functions instead of the main function, you can do so by explicitly calling the function at the beginning of the module. For example:
<code class="python">def my_function(): # 您的代码 # 在模块开头调用 my_function my_function()</code>
When you run this script, PyCharm will run the my_function function instead of the main function.
Why
PyCharm treats the main function as the entry point of the program because it is the most common convention. However, it does not require you to use the main function, nor does it limit you to running the main function.
