Python enumerate traverses array applications

Python code for traversing arrays

In other languages, such as C#, the way we usually traverse arrays is:

for (int i = 0; i < list.Length; i++)
##{
 // todo with list[i]
}

In Python, we are used to this Traversal:

for item in sequence:
process(item)

This way If the item serial number i cannot be obtained during traversal, the following traversal method is available:

for index in range(len(sequence)):
process(sequence[index])

In fact, if you know the built-in enumerate function, you can also write like this:

for index, item in enumerate(sequence):
    process(index, item)
