Handle SystemExit Exception in Python

Below are some of the solution to handle SystemExit Exception in Python:

Solution 1: Catch and Log

This approach catches the SystemExit exception so that you may record the message or take care of any issues before letting the application run again.

Python3

import sys
 
try:
    # Code that may raise SystemExit
    sys.exit("Exiting the program")
except SystemExit as e:
    print(f"Caught SystemExit: {e}")
 
# Continue with the program execution if needed
print("Program continues after handling SystemExit")

Output

Caught SystemExit: Exiting the program
Program continues after handling SystemExit

Solution 2: Wrap with Try-Except

By enclosing the sys.exit() call within a function, you may catch the SystemExit exception and manage it in a more polite manner.

Python3

import sys
 
def exit_safely(message):
    try:
        sys.exit(message)
    except SystemExit as e:
        print(f"Caught SystemExit: {e}")
         
# Call the function instead of sys.exit directly
exit_safely("Exiting the program")
 
# Continue with the program execution if needed
print("Program continues after handling SystemExit")

Output

Caught SystemExit: Exiting the program
Program continues after handling SystemExit
