Python Program to Access Index of a List Using for Loop

Table of Contents

1. Example 1: Using enumerate
2. Example 2: Start the indexing with non zero value
3. Example 3: Without using enumerate()

In this example, you will learn to access the index of a list using a for loop.

To understand this example, you should have the knowledge of the following Python programming topics:

Python for Loop
Python List
Python enumerate()

1. Example 1: Using enumerate

my_list = [21, 44, 35, 11]

for index, val in enumerate(my_list):
    print(index, val)

Output

Using enumerate(), we can print both the index and the values.

Pass two loop variables index and val in the for loop. You can give any name to these variables.
Print the required variables inside the for loop block.

The function of enumerate() is to add a counter (i.e. index) to the iterate and return it. If you want to learn more about enumerate(), please visit Python enumerate().

2. Example 2: Start the indexing with non zero value

my_list = [21, 44, 35, 11]

for index, val in enumerate(my_list, start=1):
    print(index, val)

Output

The value of the parameter start provides the starting index.

3. Example 3: Without using enumerate()

my_list = [21, 44, 35, 11]

for index in range(len(my_list)):
    value = my_list[index]
    print(index, value)

Output

You can access the index even without using enumerate().

Using a for loop, iterate through the length of my_list. Loop variable index starts from 0 in this case.
In each iteration, get the value of the list at the current index using the statement value = my_list[index].
Print the value and index.
