can you please let me know what the error here?

the error is:

File "AreaCalculator.py", line 12                                          
    print "Area %f" % area                                                   
    ^                                                                        
IndentationError: unexpected indent

looking at line 11 and 12:

  area = 3.14 * radius**2
  	print "Area %f" % area

we can indeed see the indent doesn’t match.

Hi, @web2730660785,

See the discussion, For code indentation, is a single tab equivalent to 2 spaces or 4 spaces?, then check all of your indentation. Note that the Codecademy Python content currently (July 21, 2019) uses two spaces for each level of indentation, and does not use tabs.

same issue, i recommend reformating your code outside codecademy IDE

What about resetting your tabs to 2 spaces per Tab? I have done this but is it best practices?

#7

There are soft tabs (where pressing the tab key will insert spaces) and hard tabs (special tab character). I find soft tabs to more consistent. From what I know, the majority of developers seem to prefer soft tabs, but its a never ending discussion.

also, the python style guide (link) seems to recommend 4 spaces indention. This is language specific.
