How to wait for user input in Python
This tutorial shows you how to wait for a keypress before doing something else in Python.
input()Waiting for input
in Python
input()Is a Python function that allows you to process user input in your code. It temporarily stops all processes in your code, thus acting as a stop operation.
In our case, we can use input()as a key listener to stop the process until the user presses a key. In input()the case of , the user needs to press the Enter or Return key.
Below is the sample code.
def operation1(param):
# insert code here
pass
def operation2(param):
# insert code here
pass
def operation3(param):
# insert code here
pass
input("Press enter to start operations...")
ret = operation1("Sample Param")
print("\nOperation 1 has been executed successfully.")
input("\n Press enter to start operation 2...")
ret = operation2(ret)
print("Operation 2 has been executed successfully.")
input("\n Press enter to start final operation")
ret = operation3(ret)
print("All operations executed successfully. Returned a value of ", ret)
In this way, the user needs to press the Enter key before the operation begins. At the same time, each subsequent operation also requires the user to press the Enter key, basically adding a breathing time between the three operations.
