Write text_files(folder) returning a sorted list of the file names (not full paths) in folder that end with .txt, case-insensitively (.TXT matches too). Use os.listdir.

Examples

Example 1
Input
text_files('docs')  # folder holds a.txt, b.PDF, c.TXT
Output
['a.txt', 'c.TXT']

Both .txt variants match; the PDF does not.

  • Sorted output.
