Python enumerate()

Syntax of enumerate()

The syntax of enumerate() is:

enumerate(iterable, start=0)

enumerate() Arguments

The enumerate() function takes two arguments:

• iterable - a sequence, an iterator, or objects that support iteration
• start (optional) - enumerate() starts counting from this number. If start is omitted, 0 is taken as start.

enumerate() Return Value

The enumerate() function adds counter to an iterable and returns it. The returned object is an enumerate object.

You can convert enumerate objects to list and tuple using list() and tuple() functions respectively.
