Python 3 - String

Updated: 2020-12-31

String Interning

Strings will be interned, saved as one object, so is is returning True

>>> S1 = 'spam'
>>> S2 = 'spam'
>>> S1 == S2, S1 is S2
(True, True)

Another example

>>> S1 = 'alonglongstring'
>>> S2 = 'alonglongstring'
>>> S1 == S2, S1 is S2
(True, True)

String with empty space, is is returning False

>>> S1 = 'a longer string'
>>> S2 = 'a longer string'
>>> S1 == S2, S1 is S2
(True, False)

str.maketrans()
bytes.maketrans()
bytearray.maketrans(from, to)

>>> "hello {}".format("world")
'hello world'
>>> "{} {}".format("hello", "world")
'hello world'
