Python formatting error [duplicate]

What is the issue? I tried looking for tabs, but I see none.

File "/home/pi/jasper/client/modules/Wikipedia.py", line 24
  mic.say("Okay, what would you like me to look up?")
                                                    ^

    mic.say("Okay, what would you like me to look up?")

    def sayDefinition(text):

    sayDefinition(mic.activeListen())
