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
    result = False
return result

Here is the error:

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

What's wrong with my code?

Accepted Answer

You've mixed tabs and spaces. This can lead to some confusing errors.

I'd suggest using only tabs or only spaces for indentation.

Using only spaces is generally the easier choice. Most editors have an option for automatically converting tabs to spaces. If your editor has this option, turn it on.

As an aside, your code is more verbose than it needs to be. Instead of this:

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

Just do this:

return str_p == str_q

You also appear to have a bug on this line:

str_q = p[b+1:]

I'll leave you to figure out what the error is.

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.
