Python scripts can be created and edited using many different editors. We can use different IDLEs or the command prompt to run these scripts.
Sometimes a Python program immediately closes when we run it, which can happen for several reasons.
If a Python program closes immediately, we can use the following ways to solve the problem.
input() Function to Stop the Python Program From Closing Immediately
input() function is used to read some input from the user. We can add this prompt to the end of the program to stop it from closing immediately.
This will ensure the prompt to get some user input when the end of the program is reached. We can give any input; it does not matter and press Enter because we won’t process the input anywhere in the code.
In Python 2, we have to use the
raw_input() method to get the user’s input.
-i Flag to Stop the Python Program From Closing Immediately
-i flag is used to set the inspect flag to
True when used in the command prompt. This prevents the program from exiting on
SystemExit, so it can solve a Python program from closing immediately.
When the program is finished, this option says to switch to interactive mode.
python Command to Stop the Python Program From Closing Immediately
We can run Python scripts from the command prompt. The mentioned problem is common when we ask the
cmd to run the script as the
cmd window closes when the program terminates.
If this is indeed the reason for the program closing, we can run the script differently. We can go to the script’s directory and run it using the
cd C:\User\ScriptDir python script_name.py
cd command can navigate to the required directory.
time.delay() Function to Stop the Python Program From Closing Immediately
time module provides different functions to work with time values. We can add a required-second delay using the
If a program is closing immediately, we can add this function at the end to give a little delay to observe the output properly.
import time time.sleep(20)
The above code will add a delay of 20 seconds. Alternatively, we can add empty
for loops that do nothing to create such delays.
