try-except in Python

#python

Hello! Today we will learn how to use the try-except statements. Here is a scheme of how try-except works:

try:
    # This code tries to execute, but if there's an error, stop execution
except <err_name>:
    # This code will get executed if the try block fails to execute
else:   # Optional
    # This code executes after the try block, only if try block doesn't return an error
finally:   # Optional
    # This code will always get executed

Also, you will need to replace with the error you want to catch. Ok, so let's see an example:

i = input()

try:
    i = int(i)
    print(f"Your number: {i}.")
except TypeError:
    print("Your input isn't a number!")
finally:
    print("Goodbye!")
