Another built-in method to exit a python script is quit method. They are quit exit sysexit etc which helps the user in terminating the program through the python code.
Quit It works only if the site module is imported so it should not be used in production code. PrintSum of the two numbers. Using the os_exit0 function.
How to end a program in python by using the os_exit function. The os module comes directly under pythons standard utility modules. The os module in Python is capable of providing functions for a fluent interaction with the operating system.
The python sys module can be imported and used. This module gives a convenient and portable method of. The os module comes directly under Pythons standard utility modules.
Firstly we would be using the wmi library for getting the list of the running process and later would use this list to search for our desired process and if found would terminate it. This command allows users on any version of Windows to terminate or kill any task using the process ID of the task. If you need to end a python program from the code use the sysexit function.
PrintExiting the Program exit else. Therefore it is better to use the sysexit function in production code to terminate Python scripts. This will terminate the program forcibly.
So lets understand what functions can be used below in 4 ways. Using the sysexit method. The most accurate way to exit a python program is using sysexit Using this command will exit your python program and will also raise SystemExit exception which means you can handle this exception in try except blocks.
Notice that the loop was supposed to execute 100 times but because of the sysexit method it stopped executing.

To exit the program in python the user can directly make the use of CtrlC control which totally terminates the program. The taskkill command can also be used for similar purposes.
However unlike the sysexit function the os_exit function is normally used in child processes after the osfork system call.

A intinputnEnter a Number. Another way to terminate a Python script is to interrupt it manually using the keyboard. In this article we have seen different ways to terminate a program in python.
To learn more about python programming you can read this article on list comprehension. Moreover the quit and sysexit exit functions raise SystemExit exception to terminate the given program. However if the user wishes to handle it within the code there are certain functions in python for this.
Stop a program in Python by variable status. Locate the pythonexe process that corresponds to your Python script and click the End Process. Using the os_exit 0 function.
