IndentationError when adding new line inside code [duplicate] - 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.

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.

I had a similar error while using Atom,I fixed it using below steps.
Install notepad++
Open the file which has issue(one you have mentioned in question) in notepad++.
Go to View > Show Symbol > Show All Characters,this will show up where the tabs and where spaces are available.
Go to Edit->Blank Operations->TAB to Space to replace all tabs with spaces.
Go to View > Show Symbol > Show All Characters,confirm all tabs are replaced with spaces.
Save file and reload page,this will fix this issue.

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.

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.

Pycharm sometimes does not indent the proper amount

I have tabs and indents|indent set to 2:
However the actual indentation is coming up as 3 - specifically inside the groupby function - which I have unindented and re-indented several times to be sure the behavior were consistent[-ly incorrect]:
Note that I have also tried the Auto-indent (Option-Command-I) - it also indents stuff to 3 spaces instead of 2. Bit strange..
Any thoughts?
The first thing you might want to check is to make sure you don't have Detect and use existing file indents for editing enabled in Settings/Preferences | Editor | Code Style. If you do, when you auto-indent, it might apply the wrong settings.
You can try to fix incorrectly formatted code by using Option+Command+L (Mac) / Control+Alt+L (PC), which is the Reformat Code option. That should fix the code and then auto-indent should work correctly.
This is most annoying problem in pycharm. Here is simple answer to this :
Just follow the path :
GO to Edit->Convert Indents->To Spaces
This will actually insert space instead of tabular character in empty space when you default enter for next line.

Pygame Error: TabError [duplicate]

I'm getting an IndentationError. How do I fix it?

Closed last month.
The following python code throws this error message, and I can't tell why, my tabs seem to be in line:
File "test.py", line 12
pass
^
TabError: inconsistent use of tabs and spaces in indentation
class eightPuzzle(StateSpace):
StateSpace.n = 0

StateSpace.__init__(self, action, gval, parent)
self.state = state
def successors(self) :
pass
You cannot mix tabs and spaces, according the PEP8 styleguide:
Spaces are the preferred indentation method.
Tabs should be used solely to remain consistent with code that is already indented with tabs.
Python 3 disallows mixing the use of tabs and spaces for indentation.
Python 2 code indented with a mixture of tabs and spaces should be converted to using spaces exclusively.
When invoking the Python 2 command line interpreter with the -t option, it issues warnings about code that illegally mixes tabs and spaces. When using -tt these warnings become errors. These options are highly recommended!
Using Visual Studio 2019
I was using tabs but the editor was inserting spaces and it would result in errors.
To avoid getting the spaces and tabs mixed up , set your preferences
Go to Edit->Advanced->Set Leading Whitespace->Tabs (or Whitespaces)
After I set it to Tabs, my tabs stop being represented as spaces and it worked fine thereafter
For linux nano users:
if your code includes 4 spaces instead of a tab, you should keep using 4 spaces or change all of them to a tab. If you use mixed it gives an error.
open your code in a text editor, highlight all of it (ctr+a) and go to format and select either "Tabify region" or "Untabify region". It'll just make all the indents have the same format.
not using the backspace also is important (especially in the Leafpad editor). If you want to decrease indent, use only Alt_key + TAB.
This should be done when you delete a line in a Python code.

Indentation problems in Python when using other people's files

I downloaded the source code for the famed book "Python Tkinter" by Grayson from the suggested source and loaded the first file in my Python 3.3 editor. Every line gave an indentation error. I thought it maybe a tab/indent conflict so backspaced every line then pressed enter to convert the tab to an indent – line by line and it cured the problem!
Question: Is there a way to remove tabs and convert them to indents without having to backspace then enter every line?
If you are using IDLE, do these:
do a Ctrl+H to invoke Replace.
Check the Regular expression
In the Find text field, type \t
In the Replace with text field, type four spaces
Click replace all
You can do it with sublime very easily. Look at the lower right corner. There are two buttons, the one on the left is the one you need. Click on it. It will bring up a menu. Click "Convert Indentation to spaces" from the menu. Done!

Indentation errors in python [duplicate]

This question already has answers here:
IndentationError: unindent does not match any outer indentation level
(32 answers)
Closed 4 years ago.
I am doing python programming in notepad++ ,
so as suggested in many posts I have downloaded a tool called "python indent" and set it as enable.
Even after this , when I type in the print statement still I get the indentation errors such as "IndentationError: unindent does not match any outer indentation level" , any other tool is available for this purpose?
Because in javascript ,when I select the entire file and go to jshint tool and select indentation, I just get the properly indented file .
I am searching for a tool in python , but not able to get it. Anybody has any suggestions please?
edit:
try:
print "hi"
keys = mgt.get_keys(name)
I am getting the error after inserting print statement
Sounds like you have mixed tabs and spaces in your block. Use one or the other, but not both.
There is no way to auto-indent python without understanding the code (as #alKid and #Daniel say in the comments):
For example:
if(x < y):
# Since there are no ending brackets
# how will the program
# know when you want
# to exit the indentation block?
This is likely Notepad++ inserting tabs/spaces inconsistent with your existing code. I first suggest making the spaces/tabs visible; Menu item View / Show Symbol, then select "Show White Space and Tab". I suggest using this setting for any whitespace-significant language.
I find the default settings in Notepad++ (I'm using v.6.6.7) often mess up my Python indentation. To correct this: Settings / Preferences / Tab Settings / python; uncheck "use default value" and instead specify "Replace by space."
In Sublime Text 2 there is the option to auto indent using white spaces under View > Indentation > Indent Using Whitespaces. There is also the option to convert indentation to whitespaces or convert indentation to tabs under View > Indentation > Convert Indentation to Tabs.
I know this does not address notepad++ but it is possible notepad++ has something similar available and if not this may be helpful to Sublime Text 2 users.

Python indentation borked

I saw that there are similar titles to this. But my case seems a little weirder. I somehow used a mixture of PyCharm and Vim (and within Vim I have tabstop=4 and shiftwidth=2), and my Python code seems un-fixabl-y borked, indentation-wise. I first saw that in Vim everything was mis-aligned, so I re-aligned everything; but then when I run it I get an error that there's an unexpected indentation, even though in Vim everything seems perfectly aligned. Here's an example (this is how it looks like in Vim):
for f in files:
for line in f:
items = line.strip().split()
items = items[2:]
items = ' '.join(items).split(', ')
When I run it, I get:
File "getEsSynonymLSAVectors.py", line 136
items = items[2:]
^
IndentationError: unexpected indent
I used PythonTidy, I used reindent, I tried :retab, I tried manual re-aligning - nothing seems to fix this. Any experiences/ advice will be appreciated.
Python treated a tab as 8 spaces by default, if you get indentation borked, you'll generally want to switch the tabs to spaces (or vice versa, but I generally find that spaces are easier to deal with). So make sure to set vim to show tab as 8 spaces wide (:set ts=8), to see what python sees.
To fix tab errors in vim, I usually do the following, first I need to be able to see the tabs, so I enabled highlight search (:set hlsearch) and search for tabs (/\t). Then I eyeball the areas that needs to be retabbed. Next, I try to find the right vim tab width setting for the file (:set ts=n and vary n until everything looks good), enable expand tab (:set et), then run the automatic tab fixing (:retab). When all else fail, retab manually.
If you're using version control, make sure to diff with the files before the changes and manually check that you didn't introduce a bug because of unintentional changes in the indentation level. If you don't use version control, keep a backup and run diff on the files.
Try something like this.
First set appropriate settings.
Always use 4 spaces. So change it to tabs = 4 spaces.
First convert all spaces to tabs.
And then convert all tabs to spaces.
(I use Geany)
It has worked for me before many times.
