Other posters are probably correct...there might be spaces mixed in with your tabs. Try doing a search &amp; replace to replace all tabs with a few spaces.
Try this:
<pre><code>import sys

def Factorial(n): # return factorial
 result = 1
 for i in range (1,n):
 result = result * i
 print &quot;factorial is &quot;,result
 return result

print Factorial(10)

The line: <code>result = result * i</code> should be indented (it is the body of the for-loop).

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 <a href="http://www.python.org/dev/peps/pep-0008/" rel="noreferrer">style guide</a>. You should configure Notepad++ to insert spaces for tabs.

blocks|key|2017471|text|每当我遇到这个错误时，都是因为我在编辑器中混淆了制表符和空格。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2017472|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Whenever I've encountered this error, it's because I've somehow mixed up tabs and spaces in my editor.

blocks|key|484544|text|要方便地检查制表符/空格的问题，实际上可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484545|python+-m+tabnanny+yourfile.py|code-block|syntax|javascript|484546|当然，您也可以正确设置编辑器:-)|484547|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

or you can just set up your editor correctly of course :-)

blocks|key|484563|text|看上去是个压痕问题。您不必在Python中匹配花括号，但是您必须匹配缩进级别。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484564|防止空格/制表符问题的最佳方法是在文本编辑器中显示不可见字符。这将为您提供防止和/或解决与缩进相关的错误的快速方法。|484565|此外，注入复制粘贴代码是这类问题的常见来源.|484566|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

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.

blocks|key|484585|text|这可能是因为上面的函数没有以相同的方式缩进。即|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484586|class+a:
++++def+blah:

It could be because the function above it is not indented the same way.
i.e.

<pre><code>class a:
 def blah:
 print("Hello world")
 def blah1:
 print("Hello world")
</code></pre>

blocks|key|484603|text|这是因为制表符和空格都混在一起了。您可以删除所有空格并用制表符替换它们。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|484604|或者，试着写这个：|484605|#!/usr/bin/python+-tt|code-block|syntax|javascript|484606|在代码的开头。这一行解决了制表符和空格之间的任何差异。|484607|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

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:

<pre><code>#!/usr/bin/python -tt
</code></pre>

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:

<pre><code>import sys

def Factorial(n): # Return factorial
 result = 0
 for i in range (1,n):
 result = result * i

 print "factorial is ",result
 return result
</code></pre>

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.

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.
For Spyder goto Source > Fix Indentation. Same goes to VC Code and sublime text or any other editor. Fix the indentation.

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 <code>Reformat code</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 had the same error because of another thing, it was not about tabs vs. spaces. I had the first <code>if</code> slightly more indented than an <code>else:</code> much further down. If it is just about a space or two, you might oversee it after a long code block. Same thing with docstrings:
<pre><code>&quot;&quot;&quot;comment comment 
comment
&quot;&quot;&quot;
</code></pre>
They also need to be aligned, see the <a href="https://stackoverflow.com/a/55012979/11154841">other answer</a> on the same page here.
Reproducible with a few lines:
<pre><code>if a==1:
 print('test')
 else:
 print('test2')
</code></pre>
Throws:
<pre><code> File &quot;&lt;ipython-input-127-52bbac35ad7d&gt;&quot;, line 3
 else:

It's all [tab] indentation convert to [space] indentation. Then OK.

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.
<pre class="lang-py prettyprint-override"><code> def some_instance_function(self):

 json_response = self.some_other_function()

 def compare_result(json_str, variable):
 &quot;&quot;&quot;

 &quot;&quot;&quot;
 json_value = self.json_response.get(json_str, f&quot;{json_str} not found&quot;)

 if str(json_value) != str(variable):
 logging.error(&quot;Error message: %s, %s&quot;, 
 json_value,
 variable) # &lt;-- Putting the bracket here causes the error below

 return True
