I am trying to execute the following python code:

def example(p,q):

a = p.find(" ")
b = q.find(" ")
str_p = p[0:a]
str_q = p[b+1:]

if str_p == str_q:
    result = True
else:
    result = False
return result

And I get the folloeing error:

Python requires its code to be indented and spaced properly. Never mix tabs and spaces. If you're using tabs stick to tabs and if you're using space stick to space.

Also in your code, change this part:

if str_p == str_q:
    result = True
else:
    result = False
return result

To

return str_p == str_q

Putting in an 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 amount if spacing in different editors .
