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.

Split a String:

>>> sentence = 'this is, a python, tutorial, about, idioms.'
>>> sentence.split(', ')
['this is', 'a python', 'tutorial', 'about', 'idioms.']
>>> sentence.split(', ', 2)
['this is', 'a python', 'tutorial, about, idioms.']
>>> sentence.rsplit(', ')
['this is', 'a python', 'tutorial', 'about', 'idioms.']
>>> sentence.rsplit(', ', 2)
['this is, a python, tutorial', 'about', 'idioms.']
