I want to use lstlisting for some Python code, and I have a code segment that looks like this:

documentclass[11pt]article

usepackagecolor
usepackagelistings
lstloadlanguagesPython
lstset
 language=Python,
 basicstyle=scriptsizesffamily,
 numberstyle=colorgray,
 stringstyle=color[HTML]933797
 commentstyle=color[HTML]228B22sfffamily,
 emph=[2]from,import,pass,return, emphstyle=[2]color[HTML]DD52F0,
 emph=[3]range, emphstyle=[3]color[HTML]D17032,
 emph=[4]for,in,def, emphstyle=[4]colorblue,
 showstringspaces=false,
 breaklines=true,
 prebreak=mboxcolorgraytiny$searrow$,
 numbers=left,
 xleftmargin=15pt


begindocument
beginlstlisting[language=Python]
# Function definitions

# Test cases
for _ in range(100):
 # Test comment
endlstlisting

enddocument

But the comments that start with # are not highlight with my specified color, they are just black. Any ideas?

There are three issues here: (1) gray is not defined by default in color, generally use xcolor instead. (2) there is a comma missing after stringstyle=color[HTML]933797. (3) one too many f's in sfffamily

Then the example works for me

Updated MWE:

documentclass[11pt]article

usepackagexcolor
usepackagelistings

 basicstyle=scriptsizesffamily,
 numberstyle=colorgray,
