I write a thesis and want to have my code/textfile in the appendix. I dont want to copy the code, I only want to write the path of my file into tex.

I already tried \verbatiminput{main.py} and \lstinputlisting[language=Python]{main.py} but I need to have the line numbered.

Needed features

  • numbering lines
  • load from textfile (not copying)

Nice to have features

These features would be nice, but I can manage to work around.

  • use tab as indent
  • break line, if line is to long

Not necessary at all, but very nice to have

Is there a simple way to highlight python syntax?


As MadyYuvi sugest, I tried \lstinputlisting. In one file I got an umalut (ä), so it failed to compile.
! Package inputenc Error: Invalid UTF-8 byte "A4.
In a german forum I found an suggestion to use \usepackage{listingsutf8} but it does not help.


minimal working example (MWE)




#!/usr/bin/env python3
print('I have got umlauts like ä,ö,ü in my code.')
  • try with minted.sty

May be this helps..,






If you have any special characters in programming code, then try with the below MWE:





enter image description here

Compile this file "XeLaTeX", this is because of font issues...

Also, refer this, Ulrike and egreg gave their wonderful suggestion, Characters are not displayed correctly by using FiraMono font (dvips -> ps2pdf)

  • That works for some files without umlauts in it. Do you know how to change it for umlauts?

  • Where does the umlauts come? Inside program code??

  • Can you post a MWE on your code for better understanding ?....

    I edited my question with the MWE based on your answer and a python file. Does this help you to understand my problem?
