Hi there! If you try and pass in a string that can not be converted to a number such as "hello" you will get back a ValueError. This differs slightly from TypeError. For example, the int function can take either a string or a number. But not all strings can be converted to an integer. The string "42" can be converted to an integer, but the string "my dog" can not. This is when we get a ValueError, the type of the data you're sending in (string) is supported, but the value is such that the task still cannot be completed. However, if you were to send in a list, then you would receive a TypeError as it is neither a string, nor a number.

Hope this helps! :sparkles:
