Reviewing some useful string operations

In Python, the text is represented by strings, objects of the str class. Strings are immutable sequences of characters. Creating a string object is easy—we enclose the text in quotation marks:

Python 3.5
word = 'Hello World'

Python 3.5
word = 'Hello World'
print(word[0])

Always remember to use parentheses with print, since we are coding in Python 3.x. We can similarly access other indices, as long ...
