OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.

os.abort() method in Python is used to generate a SIGABRT signal to the current process. On Unix, this method produces a core dump while on Windows, the process immediately returns an exit code of 3.
This method does not call the Python signal handler registered for SIGABRT signal with signal.signal().

Syntax: os.abort()

Parameter: No parameter is required.

Return type: This method does not return any value in the calling process.

Code #1: Use of os.abort() method

# Python program to explain os.abort() method 
# importing os module  
import os
print("Hello ! Geeks")
# os.abort() method
# will generate 'SIGABRT'
# signal to the current process
# On Unix, a core dump
# will be produced
# On windows, process
# will exit with exit code 3
# As process is aborted
# the line after os.abort() statement
# will not be executed.
print("This will not be printed")


Hello! Geeks
Aborted (core dumped)

Code #2: Use of os.abort() method

# Python program to explain os.abort() method 
# importing os module  
import os, signal
# Create a child process
# using os.fork() method 
pid = os.fork()
# pid greater than 0
# indicates the parent process 
if pid > 0:
    # Parent process    
    print("\nIn Parent process")
    # Wait for the completion 
    # of child process and get 
    # its pid and exit status indication
    # using os.wait() method 
    info = os.wait()
    sig = os.WTERMSIG(info[1]) 
    print("Child exited due to signal no:", sig)
    print("Signal name:", signal.Signals(sig).name)
else :
    # child process
    print("In child process")
    print("Process ID:", os.getpid())
    print("Hello ! Geeks")
    # Abort the child process
    # by generating SIGABRT signal
    # using os.abort() method


In child process
Process ID: 13914
Hello! Geeks

In Parent process
Child stopped due to signal no: 6
Signal name: SIGABRT
