Hi, @Baker,

Putting in extra space or leaving one out where it is needed will surely generate an error message. Some common causes of this error include:

•     Forgetting to indent the statements within a compound statement
•     Forgetting to indent the statements of a user-defined function.

The error message IndentationError: expected an indented block would seem to indicate that you have an indentation error. It is probably caused by a mix of tabs and spaces. The indentation can be any consistent white space. It is recommended to use 4 spaces for indentation in Python, tabulation or a different number of spaces may work, but it is also known to cause trouble at times. Tabs are a bad idea because they may create different amounts of spacing in different editors.
