In order to raise an error with a message in Python programming you can make use of the Exception class.
Let's say you want to raise an error when the provided age is less than 18, and the message you want to print is "Error! Age should be greater than 18!"
age = 15
if age < 18:
raise Exception("Error!, age should be greater than 18!")
Output:
Traceback (most recent call last):
File "./example.py", line 4, in <module>
Exception: Error!, age should be greater than 18!
As you can see in the above example: raise is the keyword that you should use to raise an exception.
Let's see another example: If the provided variable type is not str raise an error message.
name = 2k
if not type(name) is str:
raise TypeError("Error! Name should be a String value!")
