atom editor indentation error with Python

I am new to atom, so I opened my existing code using atom and modified few lines, then when I tried running the code with python, I get the following error:

IndentationError: unindent does not match any outer indentation level

I realized that Atom editor does indent my code differently to what I had. refer to the attached picture below showing the different indentation styles. line 1300 is the old indentation and 1301 is the one created by Atom

How can I fix this without modifying my 1000+ line code and so that atom uses the same style of indentation.

enter image description here

In the Atom Text Editor's top menu bar :

click the Packages tab

click Whitespace in the dropdown menu

Choose your preferred option (ie: Convert Spaces to Tabs)

And that will fix this pesky problem.

In the newer versions of Atom, just go to settings > Editor; then scroll down to tab length and change it to 4; then change tab type to soft. This will make the tab key insert 4 spaces instead of a tab character moving forward. You still have to update your previous code using one of the above methods.

I had a similar error while using Atom,I fixed it using below steps.

  1. Install notepad++

  2. Open the file which has issue(one you have mentioned in question) in notepad++.

  3. Go to View > Show Symbol > Show All Characters,this will show up where the tabs and where spaces are available.

  4. Go to Edit->Blank Operations->TAB to Space to replace all tabs with spaces.

  5. Go to View > Show Symbol > Show All Characters,confirm all tabs are replaced with spaces.

  6. Save file and reload page,this will fix this issue.

You have mixed tabs and spaces in your code. You should use spaces, always.

You can use this plugin to quickly fix your code, and please, use only spaces and 4 spaces for each level of indentation.
