Python IndentationError: unexpected indent
Question:
Here is my code … I am getting indentation error but i don’t know why it occurs.
->
# loop
while d <= end_date:
# print d.strftime("%Y%m%d")
fecha = d.strftime("%Y%m%d")
# set url
url = 'http://www.wpemergencia.omie.es//datosPub/marginalpdbc/marginalpdbc_' + fecha + '.1'
# Descargamos fichero
response = urllib2.urlopen(url)
# Abrimos fichero
output = open(fname,'wb')
# Escribimos fichero
output.write(response.read())
# Cerramos y guardamos fichero
output.close()
# fecha++
d += delta
Answers:
Check if you mixed tabs and spaces, that is a frequent source of indentation errors.
Run your program with
python -t script.py
This will warn you if you have mixed tabs and spaces.
On *nix systems, you can see where the tabs are by running
cat -A script.py
and you can automatically convert tabs to 4 spaces with the command
expand -t 4 script.py > fixed_script.py
PS. Be sure to use a programming editor (e.g. emacs, vim), not a word processor, when programming. You won’t get this problem with a programming editor.
PPS. For emacs users, M-x whitespace-mode will show the same info as cat -A from within an emacs buffer!
You can’t mix tab and spaces for identation. Best practice is to convert all tabs to spaces.
How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don’t mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.
Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn’t match the following identations!
find all tabs and replaced by 4 spaces in notepad ++ .It worked.
Simply copy your script and put under “”” your entire code “”” …
specify this line in a variable.. like,
a = """ your entire code """
print a.replace(' ',' ') # first 4 spaces tab second four space from space bar
print a.replace('here please press tab button it will insert some space"," here simply press space bar four times")
# here we replacing tab space by four char space as per pep 8 style guide..
now execute this code, in sublime using ctrl+b, now it will print indented code in console. that’s it
