PYTHON ERRORS AND EXCEPTIONS…OOH YEAH.

In Python, errors and exceptions are a normal part of the program development process. These errors and exceptions can occur for a variety of reasons, such as invalid syntax, missing files, or invalid input. In this post, we’ll take a closer look at how to handle errors and exceptions in Python and how it can be applied to the example of buying a car with pink stripes and polkadots.

First, let’s define what errors and exceptions are. In simple terms, errors are problems that occur during the execution of a program, and exceptions are special objects that are raised to indicate that an error has occurred. In Python, you can use the try and except statements to handle errors and exceptions and gracefully recover from them. Here’s an example of handling errors and exceptions in Python:

# Define a function that attempts to buy a car with pink stripes and polkadots
def buy_car():
  # Request the user's name
  name = input("What's your name? ")

  # Request the car's color
  color = input("What color would you like your car to be? ")

  # Check if the car's color is valid
  if color != "pink":
# Raise a ValueError exception if the color is not valid
raise ValueError(f"{name}, we're sorry but we don't have any cars with the color {color}")

#Print a success message if the color is valid
print(f"{name}, your car with pink stripes and polkadots is ready for pickup!")

#Use a try-except block to handle the ValueError exception
try:

#Call the buy_car() function
buy_car()
except ValueError as error:

#Print the error message if the exception is raised
print(error)

#Output:
What's your name? John
What color would you like your car to be? green
John, we're sorry but we don't have any cars with the color green

The `buy_car()` function requests the user’s name and the car’s color, and checks if the color is valid. If the color is not valid, it raises a `ValueError` exception with an error message. Then, the `try-except` block is used to handle the `ValueError` exception and print the error message if it is raised. Now that you know the basics of handling errors and exceptions in Python, GO HAVE SOME FUN WITH THEM.
