Set an Input Time Limit using the signal module
Signal: This module receives information from the operating system and passes it to the program in the form of signals. The signal module can be installed by running the following command in Python.
pip install signal
Example:
First of all, import the required library. Now, define custom handlers to be executed on receiving the signal using the signal() function. Also, define an alarm clock for the delivery of signals using SIGALRM. Then, create a function to take the input from the user. In the function, run the try-except statement to take input and handle the errors if any. In the try block, print any line of your choice or the question to be answered and return the taken input from the user.
Moreover, create an alarm using the alarm() function with the time specified in seconds. Next, run the function time_input() to capture the input of the user. Later on, disable the alarm after success. Finally, print the result, i.e., the value inputted by the user.
Python3
# Import the library signal import signal # Define an alarm clock for delivery of signal signal.signal(signal.SIGALRM, lambda signum, frame: print('\nYour time got over')) # Create a function to input def raw_input(): # Create a try block to take the input try: # Print the question or line of choice print("Who is your best friend?") print("You have ten seconds to answer!") # Take input from user foo = input("Enter your name!!") # Return the input to print result return foo # Define except block to catch timeout exception except Exception: return # Create an alarm using alarm function # with timer signal.alarm(10) # Run the function to # capture the input of user user_input = raw_input() # Disable the alarm after success signal.alarm(0) # Print the result input by user print('You stated your best friend name as: ', user_input) |

How to set an input time limit in Python?
In this article, we will explain how to set an input time limit in Python. It is one of the easiest programming languages which is not only dynamically typed but also garbage collected. Here we will look at different methods to set an input time limit. Below are the methods we will use in this article.
