enumerate(sequence, start=0)

Generates counter-element pairs for elements in sequence. You can set the initial counter value with start. Use this function when you need a counter for elements in a sequence. It removes the need to manually initialize and update a separate counter variable.

Parameters¶

The enumerate() function accepts two parameters:

• iterable — a sequence, iterator, or object that supports iteration.
• start (optional) — counting starts from this number. If omitted, counting begins from 0.

Return Value¶

• enumerate() adds a counter to an iterable and returns an enumerated object.
• Convert enumerated objects to a list or tuple using list() or tuple().

Examples¶

sequence = [1, 2, 7, 19]

# Using a manual counter
idx = 0
for item in sequence:
    print(idx)
    idx += 1

# Using enumerate
for idx, item in enumerate(sequence):
    print(idx)
