[python] IndentationError expected an indented block

Here is the code:

def myfirst_yoursecond(p,q):

a = p.find(" ")
b = q.find(" ")
str_p = p[0:a]
str_q = p[b+1:]

if str_p == str_q:
    result = True
else:
    result = False
return result

Here is the error:

Traceback (most recent call last):
  File "vm_main.py", line 26, in <module>
    import main
  File "/tmp/vmuser_ssgopfskde/main.py", line 22
    result = False
         ^
IndentationError: expected an indented block

What's wrong with my code?

If you are using a mac and sublime text 3, this is what you do.

Go to your /Packages/User/ and create a file called Python.sublime-settings.

Typically /Packages/User is inside your ~/Library/Application Support/Sublime Text 3/Packages/User/Python.sublime-settings if you are using mac os x.

Then you put this in the Python.sublime-settings.

{
    "tab_size": 4,
    "translate_tabs_to_spaces": false
}

Credit goes to Mark Byer's answer, sublime text 3 docs and python style guide.

This answer is mostly for readers who had the same issue and stumble upon this and are using sublime text 3 on Mac OS X.

I got the same error, This is what i did to solve the issue.

Before Indentation:

Indentation Error: expected an indented block.

After Indentation:

Working fine. After TAB space.

This error also occurs if you have a block with no statements in it

For example:

def my_function():
    for i in range(1,10):


def say_hello():
    return "hello"

Notice that the for block is empty. You can use the pass statement if you want to test the remaining code in the module.

You should install a editor (or IDE) supporting Python syntax. It can highlight source code and make basic format checking. For example: Eric4, Spyder, Ninjia, or Emacs, Vi.
