Mastering Python: Annotations, Errors and Environment
Raising
Let's learn how to raise an error.
Errors can be raised using the raise keyword:
raise TypeError
The TypeError in the example above was raised without a message.
To output an error message, you can pass a string inside the parentheses () after the error object:
raise ValueError("Wrong value!")

You have implemented the perimeter() function that returns the triangle perimeter. This function receives the sides of a triangle (a, b, and c). You need to add error raising to this function.
-
All received sides should be
intorfloatdata type. In another case, the function should raise theTypeErrorwith the message"All sides should be int or float type". -
In a triangle, all sides should have a length greater than 0. In other cases, the function should raise the
ValueErrorwith the message"All sides should be greater than 0". -
In a triangle, the sum of two sides must always be greater than the third side (otherwise, the two sides would not reach each other through the third side). Therefore, if one of the received sides is greater than the sum of the other two, the program must raise the
ValueErrorwith the message"It's not a triangle".
