A string in Python2 is a sequence of ASCII-encoded bytes. You can concatenate two strings using the ‘+’ operator. The following example prints a string and then concatenates two single-letter strings:

>>> 'abc'
'abc'
>>> 'a' + 'b'
'ab'

You can use '+' or '*' to concatenate identical strings, as shown here:

>>> 'a' + 'a' + 'a'
'aaa'
>>> 'a' * 3
'aaa'

You can assign strings to variables and print them using the print() statement:

>>> print('abc')
abc
>>> x = 'abc'
>>> print(x)
abc
>>> y = 'def'
>>> print(x + y)
abcdef

You can “unpack” the letters of a string and assign them to variables, as shown here:

>>> str = "World"
>>> x1,x2,x3,x4,x5 = str
>>> x1
