In Python, you can stop the execution of a function using various methods. The most common way is by using the return statement.
Using the return Statement
The return statement is used to exit a function and optionally pass back a value to the caller. Once the return statement is executed, the function terminates, and no further code within the function is executed1.
def my_function():print("This will be printed")returnprint("This will not be printed")my_function()Using sys.exit()
The sys.exit() function can be used to exit from Python. It raises a SystemExit exception, which can be caught in outer levels of code to handle the exit gracefully2.
import sysdef my_function():print("This will be printed")sys.exit()print("This will not be printed")try:my_function()except SystemExit:print("Function terminated")Using raise SystemExit
You can directly raise the SystemExit exception to stop the execution of a function2.
