How to Iterate Over a List in Python


How to Iterate Over a List in Python ?

Answer

To iterate over a list in Python, you can use a for loop or list comprehension.



✐ Examples

1 Iterate Over List using For Loop

In this example,

  1. We create a list named numbers with integer elements.
  2. We use a for loop to iterate over each element in the list.
  3. Within the loop, we print each element to the console.

Python Program

numbers = [10, 20, 30, 40, 50]
for num in numbers:
    print(num)

Output

10
20
30
40
50

2 Iterate Over List using List Comprehension

In this example,

  1. We create a list named numbers with integer elements.
  2. We use list comprehension to iterate over each element in the list and create a new list with modified elements.
  3. We print the new list to the console.

Python Program

numbers = [10, 20, 30, 40, 50]
doubled_numbers = [num * 2 for num in numbers]
print(doubled_numbers)

Output

[20, 40, 60, 80, 100]

Summary

In this tutorial, we learned How to Iterate Over a List in Python language with well detailed examples.
