Here is how to accesses the index in for loops in Python.

colors = ['red', 'green', 'blue']

# Loop over the elements in the list and print their index and value
for i, color in enumerate(colors):
    print(f'{i}: {color}') 

Copy & Run

To access the index of an element in a list or other iterable object in a for loop in Python, you can use the enumerate() function. This function takes an iterable object as an argument and returns an iterator that yields pairs of values, consisting of the index and the element at that index.

In the example above, the enumerate() function is used to loop over the elements in the colors list. For each element, the enumerate() function returns a pair of values consisting of the element's index (i) and the element itself (color). These values are then printed to the screen.

The enumerate() function is a convenient and efficient way to access the index of an element in a for loop. It is especially useful when you need to loop over a list and use the index of each element to access other data or perform other operations.
