How to Access Index using for Loop – Python

In Python, you can access the index of elements in a list or other iterable using a for loop in combination with the enumerate() function. enumerate() returns both the index and the value of each element, which allows you to access both within the loop.

Here’s an example:

my_list = ['a', 'b', 'c', 'd']

for index, value in enumerate(my_list):
    print(f"Index: {index}, Value: {value}")

Output:

Index: 0, Value: a
Index: 1, Value: b
Index: 2, Value: c
Index: 3, Value: d

In this example:

• enumerate(my_list) gives a sequence of tuples (index, value).
• index is the current index, and value is the corresponding value at that index.
