This is just an indentation problem since Python is very strict when it comes to it.

If you are using Sublime, you can select all, click on the lower right beside 'Python' and make sure you check 'Indent using spaces' and choose your Tab Width to be consistent, then Convert Indentation to Spaces to convert all tabs to spaces.

You might want to check you spaces and tabs  A tab is a default of 4 spaces  However  your  if  and  elif  match  so I am not quite sure why  Go into Options in the top bar  and click  Configure IDLE   Check the Indentation Width on the right in Fonts Tabs  and make sure your indents have that many spaces

in python intended block mean there is every thing must be written in manner in my case I written it this way   def btnClick numbers    global operator  operator   operator   str numbers   text input set operator    Note its give me error until I written it in this way such that  giving spaces   then its giving me a block as I am trying to show you in function below code  def btnClick numbers                                global operator  operator   operator   str numbers   text input set operator

As the error message indicates  you have an indentation error  It is probably caused by a mix of tabs and spaces

There are in fact multiples things you need to know about indentation in Python   Python really cares about indention   In a lot of other languages the indention is not necessary but improves readability  In Python indentation replaces the keyword begin   end or     and is therefore necessary   This is verified before the execution of the code  therefore even if the code with the indentation error is never reached  it won t work   There are different indention errors and you reading them helps a lot   1   IndentationError  expected an indented block   They are two main reasons why you could have such an error   - You have a     without an indented block behind   Here are two examples   Example 1  no indented block   Input   if 3    4      print  usual   else    Output     File   lt stdin gt    line 4        IndentationError  expected an indented block   The output states that you need to have an indented block on line 4  after the else  statement  Example 2  unindented block   Input   if 3    4  print  usual     Output    File   lt stdin gt    line 2     print  usual             IndentationError  expected an indented block   The output states that you need to have an indented block line 2  after the if 3    4  statement  - You are using Python2 x and have a mix of tabs and spaces   Input  def foo        if 1          print 1   Please note that before if  there is a tab  and before print there is 8 spaces   Output     File   lt stdin gt    line 3     print 1         IndentationError  expected an indented block   It s quite hard to understand what is happening here  it seems that there is an indent block    But as I said  I ve used tabs and spaces  and you should never do that    You can get some info here   Remove all tabs and replaces them by four spaces  And configure your editor to do that automatically    2   IndentationError  unexpected indent   It is important to indent blocks  but only blocks that should be indent  So basically this error says   - You have an indented block without a     before it   Example   Input   a   3   a    3   Output     File   lt stdin gt    line 2     a    3       IndentationError  unexpected indent   The output states that he wasn t expecting an indent block line 2  then you should remove it   3   TabError  inconsistent use of tabs and spaces in indentation   python3 x only    You can get some info here  But basically it s  you are using tabs and spaces in your code  You don t want that   Remove all tabs and replaces them by four spaces  And configure your editor to do that automatically     Eventually  to come back on your problem   Just look at the line number of the error  and fix it using the previous information

I had this same problem and discovered  via this answer to a similar question  that the problem was that I didn t properly indent the docstring properly  Unfortunately IDLE doesn t give useful feedback here  but once I fixed the docstring indentation  the problem went away   Specifically --- bad code that generates indentation errors   def my function args    Here is my docstring             Good code that avoids indentation errors   def my function args        Here is my docstring             Note  I m not saying this is the problem  but that it might be  because in my case  it was
