How to get the index of the current iterator item in a loop in python?

You can use the built-in enumerate() function in Python to iterate over a sequence (e.g., list, tuple, string) and obtain both the current item and its index. Here's how to use it in a loop:

items = ['apple', 'banana', 'cherry', 'date']

for index, item in enumerate(items):
    print(f"Index: {index}, Item: {item}")

Output:

Index: 0, Item: apple
Index: 1, Item: banana
Index: 2, Item: cherry
Index: 3, Item: date

In this example, the enumerate() function is used to generate pairs of (index, item) for each item in the list. The loop then iterates over these pairs, allowing you to access both the index and the item in each iteration.

Remember that the index starts from 0 by default. If you want the index to start from a different value, you can provide a second argument to the enumerate() function:

items = ['apple', 'banana', 'cherry', 'date']

for index, item in enumerate(items, start=1):
    print(f"Index: {index}, Item: {item}")

Output:

Index: 1, Item: apple
Index: 2, Item: banana
Index: 3, Item: cherry
Index: 4, Item: date

In this example, the start parameter is set to 1, so the index starts from 1 instead of the default 0.
