"Inconsistent use of tabs and spaces indentation"

Question

I'm trying to create an application in Python 3.2, and I always use tabs for indentation, but even the editor changes some of them to spaces, and then prints "inconsistent use of tabs and spaces in the indentation" when I try to run the program.

How to change spaces to tabs? It drives me crazy. (I am new to programming). I would be glad if I could get some general advice on my code, if I made many mistakes, I would be happy to hear.

import random attraktioner = ["frittfall","bergodalbana","spökhuset"] class Nojesfalt: def __init__(self, attraktion): self.val = attraktion self.langd = 0 self.alder = 0 #längdgräns för fritt fall def langdgrans(self): print("") self.langd = int(input("Hur lång är du i cm? ")) if self.langd < 140: print("tyvärr, du är för kort, prova något annat") return 0 elif self.langd >= 140: print("håll dig hatten, nu åker vi!") print(" ") return 1 #åldersgräns för spökhuset def aldersgrans(self): print("") self.alder = int(input("Hur gammal är du? ")) if self.alder < 10: print("tyvärr, du är för ung, prova något annat") return 0 elif self.alder >= 10: print("Gå in om du törs!") print(" ") return 1 #åker attraktion frittfall lr bergodalbana def aka(self): print("") print(self.val) tal = random.randint(0,100) if tal < 20: print("åkturen gick åt skogen, bättre lycka nästa gång") elif tal >= 20: print("jabbadabbbadoooooooo") return 1 #går i spökhuset def aka1(self): print("") print(self.val) tal = random.randint(0,100) if tal < 20: print("du är omringad av spöken och kan inte fortsätta") return 0 elif tal >= 20: print("Buhuuuuuu, buuuhuuuu") return 1 #programkod print("Välkommen till nöjesfältet, vad vill du göra?") print(" ") while 1: vald_attr = input("Vad vill du göra?\n1. frittfall\n2. bergodalbana\n3. spökhuset\n4. Avsluta\n") if vald_attr == "1": val = Nojesfalt(attraktioner[0]) if val.langdgrans() == 1: val.aka() elif vald_attr == "2": val = Nojesfalt(attraktioner[1]) val.aka() elif vald_attr == "3": val = Nojesfalt(attraktioner[2]) if val.aldersgrans() == 1: val.aka1() elif vald_attr == "4": break 

Answer 1

Do not use tabs.

• Set 4 spaces for indentation in the editor.
• Do a search and replace to replace all tabs with 4 spaces.
• Make sure your editor is set to display tabs as 8 spaces.

Note. The reason for the 8 spaces for tabs is that you will immediately notice when the tabs were pasted unintentionally - for example, when copying and pasting code from an example that uses tabs instead of spaces.

Answer 2

With the IDLE editor you can use this:

• Edit Menu → Select All
• Menu Format → Untabify Region
• Assuming your editor has replaced 8 spaces in a tab, enter 8 in the input field.
• Press select and it will fix the whole document.

Answer 3

Using the autopep8 below fixed this for me:

  autopep8 -i my_file.py 

The documentation for autopep8 here.

Answer 4

As a rule, people prefer padding with space. This is more consistent between editors, resulting in fewer inconsistencies of this kind. However, you are allowed to backtrack with the tab. This is your choice; however, you should be aware that the standard of 8 spaces per tab is a little wide.

As for your problem, most likely your editor is messed up. Converting a tab to space actually depends on the editor.

For example, in Emacs, you can call the "untabify" method.

On the command line, you can use the sed line (adapt the number of spaces to whatever pleases you):

  sed -e 's;\t; ;' < yourFile.py > yourNedFile.py 

Answer 5

If you use Sublime Text to develop Python, you can avoid the error by using the Anaconda package. After installing Anaconda, open the file in Sublime Text, right-click on open spaces -> select Anaconda -> click on autoformat. Done. Or press Ctrl + Alt + R.

Answer 6

I recently had the same problem and it turned out that I just needed to convert the encoding of the .py file to UTF-8, as this uses the Python 3 suite.

By the way, I used 4-space tabs all the time, so the problem was not caused by them.

Answer 7

What I did when the same error appeared: select all ( Str + A ) and press Shift + Tab . So there was nothing else. Now go back to the lines you want to indent and return them as you want.

It worked for me ...

Answer 8

Amazing text 3

In Sublime Text, when editing a Python file :

Sublime Text Menu > Settings > Settings - Syntax :

Python.sublime setup

 { "tab_size": 4, "translate_tabs_to_spaces": true } 

Answer 9

This problem can be solved with notepad++ by replacing Tab with 4 Space :

1. Choose Search → Find ... or press Ctrl + F
2. Select the Replace tab
3. In the "Search Mode" field, select "Advanced" (\ n, \ r, \ t, \ 0, \ x ...)
4. .In the Find what field: write \ t
5. In the Replace with: field, click Space 4 times. Make sure there is nothing else in this field.
6. Click on the Replace All button.

Answer 10

I had this problem. Solution: your tab before the problem is spaces, 4, 6 or 8 spaces. You must delete them and paste the TAB. '\ T'. All this.

Answer 11

I am using Notepad ++ and got this error.

In Notepad ++, you will see that the tab and the four spaces are the same, but when you copy the code in Python IDLE, you will see the difference, and the line with the tab will have more space in front of it than the rest.

To solve the problem, I simply removed the tab before the line and added four spaces.

Answer 12

Your problem is with the limitations / configuration of your editor. Some editors provide you with tools to solve this problem:

1. Convert tabs to spaces

   For example, if you use the Stani Python editor, you can configure it to save.

2. Convert spaces to tabs

If you use ActiveState Komodo, you have a tool to “tabulate” your code. As others have already pointed out, this is not a good idea.

Eclipse Pydev provides the Convert Tabs to Spaces and Convert Spaces To Bookmarks features.

Answer 13

I had the same error. I had to add a few lines of code to an existing * .py file. In Notepad ++, this did not work.

After adding lines of code and saving, I got the same error. When I opened the same file in PyCharm and added the lines, the error disappeared.

Answer 14

I got the same errors but couldn’t understand what I was doing wrong.

So I fixed it by executing the automatic code in my code and letting the machine fix my error.

If someone is wondering how I did it. Simply. Go to vim. Enter G = gg.

This will automatically fix everything. Good luck :)

Answer 15

Sometimes a tab makes a mess during indentation. One way is to explicitly use tab and backspace to properly indent the code.

Another way is to use space 4 times (depending on how much you want to backtrack).

A strange way that worked for me when nothing worked, depending on which line I get the error, I backspaced this line to the previous line, and then hit enter . He automatically stepped back from the line for the correct position, and after that I did not get any errors.

Hope this helps.

Answer 16

I had the same problem and fix it using the following python script. Hope this helps others.

this involves using tabs and spaces for backing code. in this script, I replace each tab with four spaces.

 input_file = "source code path here" # eg source.py output_file = "out put file path here" # eg out.py with open(input_file, 'r') as source: with open(output_file, 'a+') as result: for line in source: line = line.replace('\t', ' ') result.write(line) 

if you use sublime or any other editor that gives you a tool for replacing text, you can replace all tabs with four spaces from the editor.

Answer 17

Another reason I don't like Python ...

If the same problem (although I used tabs sequentially, set my IDE to read 4 spaces as tabs, and in the view all indents with the code are displayed correctly and aligned).

Fortunately, this was only one line that made an error, but as soon as I deleted the tabs and entered an equivalent number of spaces, the problem was fixed.

Answer 18

If your editor does not recognize the tabs when performing searches and replacements (e.g. SciTE), you can paste the code into Word and search using Ctr-H and ^ t, which find tabs that can then be replaced with 4 spaces.

Answer 19

From here there was a duplicate of this question, but I thought that I could offer an idea of ​​modern editors and the huge number of functions that they offer. In Python code, everything that needs to be placed in a .py file must be either entirely using the tab key or spaces. The convention is to use four spaces to indent. Most editors have the ability to visually show in the editor whether the code is indented from spaces or tabs, which helps a lot when debugging. For example, with an atom, going to settings and then the editor, you can see the following two options:

Then, if your code uses spaces, you will see small dots where your code is indented:

And if you indent using tabs, you will see something like this:

Now, if you notice, you can see that when using the tabs on the left there are more errors / warnings, this is due to what pep8 is called, the pep8 documentation , which basically is a single style guide for python, so that’s all developers basically write code the same standard and appearance that helps when trying to understand other people's code, it is in pep8, which prefers to use spaces for indentation rather than tabs. And we see that the editor shows that there is a warning regarding warning code W191 ,

I hope that all of the above will help you understand the nature of the problem you are facing and how to prevent it in the future.

Answer 20

Use Idle for python or Idle3 for python3.

Answer 21

Your code must be consistent. Either use the entire spaces (4 spaces are recommended), or use the entire tabs. This has nothing to do with IDEs or text editors.

Answer 22

Solving this problem using the Vim editor

1. Open terminal ( Ctrl + Alt + T ).
2. Change to the directory where the file is located ( cd <path_to_your_directory> ). Example: cd /home/vineeshvs/work .
3. Open the file in Vim ( vim <file_name> ). Example: vim myfile.txt .
4. [Optional step] Turn on search keyword highlighting in Vim ( ESC :set hlsearch )
5. Go to the line where you have this problem ( ESC :<line_number> ). Example:: :53 in the Vim editor after pressing the ESC button once.
6. Replace the tab using the required number of spaces in Vim ( :.,$s/\t/<give_as_many_spaces_as_you_want_to_replace_tab>/gc ). Example: Tab will be replaced with four spaces with the following command:: :.,$s/\t/ /gc after pressing the ESC button once). This process is interactive. You can give y replace the tab with spaces and n skip the specific replacement. Press ESC when done with the necessary replacements.

Answer 23

Highlight the indented bits and click the tabs. Then they will become consistent :)
