enumerate(sequence, start=0)
Return an enumerate object. sequence must be a sequence, an iterator, or some other object which supports
iteration. The next() method of the iterator returned by enumerate() returns a tuple containing a
count (from start which defaults to 0) and the values obtained from iterating over sequence:
>> >>> seasons = ['Spring', 'Summer', 'Fall', 'Winter'] >>> list(enumerate(seasons)) [(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')] >>> list(enumerate(seasons, start=1)) [(1, 'Spring'), (2, 'Summer'), (3, 'Fall'), (4, 'Winter')]
Equivalent to:
def enumerate(sequence, start=0): n = start for elem in sequence: yield n, elem n += 1
New in version 2.3.
Changed in version 2.6: The start parameter was added.
