Python "expected an indented block"

Question

Let me start off by saying that I am COMPLETELY new to programming. I have just recently picked up Python and it has consistently kicked me in the head with one recurring error -- "expected an indented block" Now, I know there are several other threads addressing this problem and I have looked over a good number of them, however, even checking my indentation has not given me better results. I have replaced all of my indents with 4 spaces and even rewritten the code several times. I'll post this counter assignment I got as an example.

option == 1 while option != 0:     print "MENU"     option = input()     print "please make a selection"     print "1. count"     print "0. quit"     if option == 1:         while option != 0:             print "1. count up"             print "2. count down"             print "0. go back"             if option == 1:                 print "please enter a number"                 for x in range(1, x, 1):                     print x                 elif option == 2:                     print "please enter a number"                     for x in range(x, 1, 1):                 elif option == 0:                     break                 else:                     print "invalid command"     elif option == 0:         break 

Answer 1

Starting with elif option == 2:, you indented one time too many. In a decent text editor, you should be able to highlight these lines and press Shift+Tab to fix the issue.

Additionally, there is no statement after for x in range(x, 1, 1):. Insert an indented pass to do nothing in the for loop.

Also, in the first line, you wrote option == 1. == tests for equality, but you meant = ( a single equals sign), which assigns the right value to the left name, i.e.

option = 1
