Basic Exception Handling

Snippet

Using try and except blocks prevents your program from crashing when an error occurs by allowing you to handle the exception gracefully.

snippet.py
python
try:
    number = int("not_a_number")
except ValueError:
    print("Caught an error: That was not a valid number!")

Breakdown

try:

Begins a block where you expect a potential error might happen.

except ValueError:

Executes this code block only if a ValueError occurs inside the try block.
