How to Specify TypeError Output in Python?

Estimated read time 1 min read

When you encounter a TypeError in Python, it means that you are trying to perform an operation on a variable of the wrong type. You can specify a custom error message to be displayed when a TypeError is raised using the raise statement.

Here’s an example of how you can specify a custom TypeError message:

x = "hello"

if not isinstance(x, int):
    raise TypeError("Expected an integer value for x, but received a {}.".format(type(x).__name__))

In this example, we are checking if the variable x is an integer using the isinstance() function. If x is not an integer, we raise a TypeError with a custom message that tells the user what type of value was expected and what type of value was received.

You can replace the message in the raise statement with any custom message that you want. Just be sure to include the relevant information about the expected and received types to make it clear to the user what went wrong.
