Why Isn\'t My Python `main()` Function Running?

main() Function Not Running?

When attempting to execute a Python script containing a defined main() function, users may encounter an issue where the function does not execute. This may leave the user confused as there are no apparent errors or output.

To resolve this issue, it's crucial to understand that simply defining a function does not invoke its code. To execute the function and perform its intended actions, you must explicitly call it.

For instance, consider the following code:

<code class="python">def main():
    print("boo")</code>

When executed, this code will not print "boo" because the main() function is only defined but not called. To execute the function and print "boo," you must add the following line to the code:

<code class="python">main()</code>

This ensures that the main() function is called and its code is executed, resulting in the desired output. Remember, call the function after defining it to run its code.
