Question

When I compile the Python code below, I get

IndentationError: unindent does not match any outer indentation level

---

import sys  def Factorial(n): # Return factorial     result = 1     for i in range (1,n):         result = result * i     print "factorial is ",result     return result 

Why?

Answer 1

One possible cause for this error is that there might be spaces mixed with tabs for indentation. Try doing a search & replace to replace all tabs with a few spaces.

Try this:

import sys  def Factorial(n): # return factorial     result = 1     for i in range (1,n):         result = result * i     print "factorial is ",result     return result  print Factorial(10)
