How to Fix Input ValueError Crash in Python | Try Except Tutorial
на канале: TutsCode
Hello everyone! In this quick Python explainer, we look at a very common beginner mistake: what happens when your user inputs text instead of a number into an int(input( )) function.
By default, this triggers a ValueError and instantly crashes your application. To fix this, we explore how to use the built-in Python structural keywords: 'try' and 'except' to handle exceptions safely without crashing the program.
*Correction Note: In the flow of recording, I accidentally referred to try and except as "methods"—they are technically structural keywords (like if and else) used for exception handling blocks!
📌 Code used in this video:
try:
age=int(input("What is your age? "))
print(f"You are {age} old")
except ValueError:
print("Please enter a valid number for age.")
