4 Ways to Iterate Arrays in Python

In Python, there are various methods to iterate through an array, such as:

1. “Using a for loop:”

arr = [1, 2, 3, 4, 5]
for element in arr:
    print(element)

1. Utilizing a while loop and an index:

arr = [1, 2, 3, 4, 5]
index = 0
while index < len(arr):
    print(arr[index])
    index += 1

1. Utilize the enumerate() function:

arr = [1, 2, 3, 4, 5]
for index, element in enumerate(arr):
    print(f"Index {index}: {element}")

1. Utilize the zip() function (used for iterating over multiple arrays simultaneously):

arr1 = [1, 2, 3]
arr2 = ['a', 'b', 'c']
for element1, element2 in zip(arr1, arr2):
    print(f"{element1} - {element2}")

1. Utilizing list comprehension:

arr = [1, 2, 3, 4, 5]
[print(element) for element in arr]

These methods allow for choosing the appropriate way to traverse an array based on specific needs.
