Python is an very nice high-level programming language that provides the user with an easy way to write readable and clean code. It is often the case when someone is learning a new tool or language that they are not aware of small features that would greatly improve the readability of their code.
For example, when I was learning Python I learned to iterate over a list the way I keep seeing it when reading code of beginner Pythonists. Here is an example of how you could iterate over the list:
for ix in range(len(a_list)): print(a_list[ix])
However, a better and Pythonic way is to use iterators:
for el in a_list: print(el)
This equally works for dictionaries and strings:
for key in a_dictionary: print(key) for char in a_string: print(char)
