Other posters are probably correct…there might be spaces mixed in with your tabs. Try doing a search & replace to replace all tabs with a few spaces.
Try this:
import sys
def Factorial(n): # return factorial
result = 1
for i in range (1,n):
result = result * i
print "factorial is ",result
return result
print Factorial(10)

IMPORTANT:
Spaces are the preferred method — see PEP 8 Indentation and Tabs or Spaces?. (Thanks to @Siha for this.)
For Sublime Text users:
Set Sublime Text to use tabs for indentation:
View —> Indentation —> Convert Indentation to Tabs
Uncheck the Indent Using Spaces option as well in the same sub-menu above.
This will immediately resolve this issue.

Are you sure you are not mixing tabs and spaces in your indentation white space? (That will cause that error.)
Note, it is recommended that you don’t use tabs in Python code. See the style guide. You should configure Notepad++ to insert spaces for tabs.

If you use Python’s IDLE editor you can do as it suggests in one of similar error messages:
1) select all, e.g. Ctrl + A
2) Go to Format -> Untabify Region
3) Double check your indenting is still correct, save and rerun your program.

Looks to be an indentation problem. You don’t have to match curly brackets in Python but you do have to match indentation levels.
The best way to prevent space/tab problems is to display invisible characters within your text editor. This will give you a quick way to prevent and/or resolve indentation-related errors.
Also, injecting copy-pasted code is a common source for this type of problem.

This is because there is a mix-up of both tabs and spaces.
You can either remove all the spaces and replace them with tabs.
Or,
Try writing this:

at the beginning of the code. This line resolves any differences between tabs and spaces.

Firstly, just to remind you there is a logical error you better keep result=1 or else your output will be result=0 even after the loop runs.
Secondly you can write it like this:
import sys
def Factorial(n): # Return factorial
result = 0
for i in range (1,n):
result = result * i
print "factorial is ",result
return result
Leaving a line will tell the python shell that the FOR statements have ended. If you have experience using the python shell then you can understand why we have to leave a line.

For example:
1. def convert_distance(miles):

In this code same situation occurred for me. Just delete the previous indent spaces of
line 2 and 3, and then either use tab or space. Never use both. Give proper indentation while writing code in python.

I got this error even though I didn’t have any tabs in my code, and the reason was there was a superfluous closing parenthesis somewhere in my code. I should have figured this out earlier because it was messing up spaces before and after some equal signs… If you find anything off even after running Reformat code in your IDE (or manually running autopep8), make sure all your parentheses match, starting backwards from the weird spaces before/after the first equals sign.

I actually get this in pylint from a bracket in the wrong place.
I’m adding this answer because I sent a lot of time looking for tabs.
In this case, it has nothing to do with tabs or spaces.
def some_instance_function(self):
json_response = self.some_other_function()
def compare_result(json_str, variable):
"""
Sub function for comparison
"""
json_value = self.json_response.get(json_str, f"{json_str} not found")
if str(json_value) != str(variable):
logging.error("Error message: %s, %s",
json_value,
variable) # <-- Putting the bracket here causes the error below
#) <-- Moving the bracket here fixes the issue
return False
return True
logging.debug("Response: %s", self.json_response)
# ^----The pylint error reports here
