Python’s Enumerate Function
This is Python’s built-in function which is used to count an iterable and return it as an enumerated object.
Syntax:
enumerate(iterable, start=0)
Scope:
To iterate over an iterable data type and return an enumerated object (iterator) that yields tuples of (index, value), whose index starts from 0 by default.
Example:
lang_order = [‘Python’, ‘Java’, ‘C++’, ‘C’, ‘COBOL’]
print(list(enumerate(lang_order)))
Purpose: To simplify counting iterables by eliminating manual counting.
