When programming in Python, sometimes our program gets stuck in an infinite loop. In this case, we need to terminate the program manually.

This article will discuss different ways to kill a Python process.

Killing a Python process using a keyboard shortcut

The easiest way to kill a Python process is to use the keyboard shortcut CTRL+ C.

Whenever a Python program runs into an infinite loop, you can press CTRL+ in your IDE or in the terminal where the program is running C. After pressing the key, the Python process will terminate immediately.

Sometimes, if the Python program is busy executing a system call, you cannot terminate it normally. In this case, we have to terminate the Python process manually from the command line.

Using command line statements, we need to send a SIGTERMsignal to the program to terminate. Let us discuss the different ways to terminate a Python process using the command line.

killKill the Python process using the process name and command

killWe will follow these steps to kill Python process using command in Linux . First, we will list all the running Python processes using pscommand and kill as shown below.grep

Here, psthe command first lists all the running processes. grepThe command filters all the processes that contain Python in their name and then displays the output to the user.

You can see that the second item in the output is a number. This number is the process ID of the Python program.

Using the following syntax, we can kill the Python process using the process_idand commands.kill

kill process_id

Here, process_idis the process ID of the program we want to terminate. You can killterminate all Python processes using the statement and the process ID of the program.

For example, we can kill the third Python process in the figure above using the following command:

kill 9146

killallKill the Python process using the process name and command

killallInstead of manually terminating the Python processes using the statement, we can use the command to kill all Python processes at once kill.

killallThe command takes the name of a process as input. When executed, it kills all processes with the given name.

You can killallkill all Python processes using the command as shown below.

killall python

pkillKill the Python process using the process name and command

In addition to killallthe kill command, we can pkillkill the Python process using the kill command. pkillThe kill command takes the name of the process as an input parameter.

When executed, it SIGTERMsends the signal to all processes with the given name in the input. As a result, all processes with the given name will be terminated.

Using the following statement, you can pythonpass the name to pkillthe command to kill the Python process.

pkill python

in conclusion

In this article, we discussed different ways to kill a Python process. To kill a specific Python program, you can use the kill psand grepkill commands along with killthe kill command.

To kill all Python processes at once, you can use killallthe command or pkillthe command.
