You probably have a mixture of spaces and tabs in your original source file. Replace all the tabs with four spaces (or vice versa) and you should see the problem straight away.

Your code as pasted into your question doesn't have this problem, but I guess your editor (or your web browser, or Stack Overflow itself...) could have done the tabs-to-spaces conversion without your knowledge.

It s possible that you have mixed tabs and spaces in your file  You can have python help check for such errors with  python -m tabnanny  lt name of python file gt

I had this problem with PyCharm as well  I went up to the code menu and selected reformat code  Problem went away

Geany has an option in its menus that says  Apply Default Intendation  which replaces tabs by the number of spaces if specified in Geany s settings

I had this same problem and it had nothing to do with tabs  This was my problem code   def genericFunction variable        for line in variable          line   variable      if variable    None        return variable   Note the above for is indented with more spaces than the line that starts with if  This is bad  All your indents must be consistent  So I guess you could say I had a stray space and not a stray tab

I have this issue  This is because wrong space in my code  probably the next line delete all space and tabs and use space

User · Answer

If you re VSCode user  then you probably have Insert Spaces option checked  This will replace every tab you press by spaces which leads to this issue  Uncheck it and you re good to go

Sorry I can t add comments as my reputation is not high enough  -   so this will have to be an answer   As several have commented  the code you have posted contains several  5  syntax errors  twice   instead of    and three     missing    Once the syntax errors corrected I do not have any issue  be it indentation or else  of course it s impossible to see if you have mixed tabs and spaces as somebody else has suggested  which is likely your problem    But the real point I wanted to underline is that  tabnanny IS NOT REALIABLE  you might be getting an  indentation  error when it s actually just a syntax error   Eg  I got it when I had added one closed parenthesis more than necessary  -   i     func a  b   c  if True else None      would provoke a warning from tabnanny for the next line   Hope this helps

I had this issue with code that I copied from a blog  I got rid of the issue on PyCharm by Shift Tab ing unindenting  the last error-throwing code-block all the way to the left  and then Tab ing it back to where it was  I suppose is somehow indirectly working the same as the  reformat code  comment above

Maybe it s this part   if speed       gt  self buginfo  maxspeed    self buginfo  maxspeed     speed if generation  gt  self buginfo  maxgen      self buginfo  maxgen       generation   Try to remove the extra space to make it look aligned   Edit  from pep8     Yes         x   1       y   2       long variable   3    No         x               1       y               2       long variable   3    Try to follow that coding style

I had a similar problem with IndentationError in PyCharm   I could not find any tabs in my code  but once I deleted code AFTER the line with the IndentationError  all was well   I suspect that you had a tab in the following line           sex     sex   if not sex      2 else random randint 0 1

IDLE TO VISUAL STUDIO USERS  I ran into this problem as well when moving code directly from IDLE to Visual Studio  When you press tab IDLE adds 4 spaces instead of a tab  In IDLE  hit Ctl A to select all of the code and go to Format Tabify Region  Now move the code to visual studio and most errors should be fixed  Every so often there will be code that is off-tab  just fix it manually

I am using gedit basic version that comes with Ubuntu 11 10  I had the same error  This is mainly caused when you mix spaces with tabs   A good way to differentiate as to which lines have problem would be to go to  1  edit 2  preferences 3  editor 4  check  automatic indentation  5  increase the indentation to 12 or some big number  after doing the fifth step you will be able to see the lines of your code that are relly causing problem  these are the lines that have a mix of space and tab   Make the entire code convention as just TAB or just SPACE  this has to be done manually line by line   Hope this helps

Don t forget the use of     comments  These need precise indentation too  a 1 2 hr job for me resolving this damn error too

User · Answer

I would recommend checking your indentation levels all the way through   Make sure that you are using either tabs all the way or spaces all the way  with no mixture   I have had odd indentation problems in the past which have been caused by a mixture
