How can I reduce nested if statements in the python code

Question

if flask.request.form['token'] == stored_token:
 if size_of_file > 10000:
 logging.info('data ' + filename + ' is compressed and sent')
 return gzip_compress(resp(200, data))
 else:
 logging.info(filename + ' data copy')
 return resp(200, data)
else:
 logging.info(' data ' + filename + ' is not compressed, but copied and sent')
 return resp(401, {})

I do not like how this code looks to help fix it. Or tell me that this is a good code.

• Onyambu: you think does not mean it is bad. This is just a nested if statement. who said it is bad??
• TomBombadil: If you have questions about the quality of code, consider posting your question the code review forum.
• TomBombadil: Anyway I do not see any problem with this code...

Here you go:

if flask.request.form['token'] != stored_token:
 logging.info(' data ' + filename + ' is not compressed, but copied and sent')
 return resp(401, {})
if size_of_file <= 10000:
 logging.info(filename + ' data copy')
 return resp(200, data)
logging.info('data ' + filename + ' is compressed and sent')
return gzip_compress(resp(200, data))

In google testing blog there is an article describing why nested if statements are considered bad and how can you reduce your code complexity.
