Python is a great object-oriented, interpreted, and interactive
programming language. It is often compared (favorably of course :-) )
to Lisp, Tcl, Perl, Ruby, C#, Visual Basic, Visual Fox Pro, Scheme or Java...
and it's much more fun.

Sample Solution:

Python Code:

import glob
char_list = []
files_list = glob.glob("*.txt")
for file_elem in files_list:
   with open(file_elem, "r") as f:
       char_list.append(f.read())
print(char_list)

Sample Output:

["Python is a great object-oriented, interpreted, and interactive\nprogramming language. It is often compared (favorably of course :-) )\nto Lisp, Tcl, Perl, Ruby, C#, Visual Basic, Visual Fox Pro, Scheme or Java...\nand it's much more fun.", 'Welcome to the Python Wiki, a user-editable compendium of knowledge\nbased around the Python programming language.
