Listings is a very good LaTeX package if you want to implement python, or any other code into your document. However, when I was installing the package, I constantly got the error that “listings.sty” is missing, despite MiKTeX downloading it for me. The solution to this problem is straightforward:

1. Find “latex.exe” and launch it.
2. Type “$ texhash” (without the “”)
3. Type the file “listings.sty”
4. Done! If you get an error that a you need to specify the log file, just skip it, it will work without it!
