This tutorial shows you how to wait for key press in Python before proceeding with other operations.

Use input() to Wait for Input in Python

input() is a Python function that allows user input to be processed within the code. It temporarily halts all processes within the code therefore acts as a stopper to operations that are done.

In our case, we can use input() as a key-listener to stop processes until the user presses a certain key. In the case of using input(), user needs to press enter or return key.

Below is the example code.

def operation1(param):
    # insert code here

def operation2(param):
    # insert code here

def operation3(param):
    # insert code here

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)

This way, before operations start, user needs to press Enter. Also, each subsequent operation needs user to press Enter as well, essentially adding a breather between the 3 operations.
