What is Enumerate in Python

The enumerate() function in Python adds a counter to the iterable and returns an enumerate object. While dealing with iterables, there may arise some situations where we need to add a counter as a key to the iterable. In such cases, the enumerate() method comes useful. This enumerate object can then be used directly in for loops or be converted into a list of tuples using list() method

Syntax: enumerate(iterable, start=0)

• Iterable – any object that supports iteration
• Start: the index value from which the counter is to be started, by default it is 0.

Let us see an example and understand this method.

li = ["red", "blue", "green"]
ob1 = enumerate(li)
print(type(ob1))
print(ob1)
print(list(ob1))

print()

st = "Python"
ob2 = enumerate(st)
print(type(ob2))
print(ob2)
print(list(ob2))

Output:

<class 'enumerate'>
<enumerate object at 0x0000024A02670440>
[(0, 'red'), (1, 'blue'), (2, 'green')]

<class 'enumerate'>
<enumerate object at 0x0000024A02670500>
[(0, 'P'), (1, 'y'), (2, 't'), (3, 'h'), (4, 'o'), (5, 'n')]
