Joining Strings in Python

Today we’ll be talking about joining strings. We can join strings using the method join.

The method join(seq) takes the string elements from a sequence and concatenates them using the string as the separator. Here’s how we can use it with a string:

>>> separator = " <*> "
>>> sequence = "star"    # with a string
>>> separator.join(sequence)
's <*> t <*> a <*> r'
