Day 7: Looping through Lists

Task

Practice using loops to iterate over items in a list.

Description

Loops are useful for working with lists in Python, as they allow you to perform actions on each item in the list automatically. The for loop is commonly used to iterate over lists, making it easy to access each element in sequence.

Key Concepts

  • For Loops: Use for loops to go through each item in a list.
  • Range: Use range() with loops to control the number of iterations.
  • Enumerate: Use enumerate() to get both the index and the value of each item in the list.

Example

# Define a list of colors
colors = ["red", "blue", "green", "yellow"]

# Loop through each color and print it
for color in colors:
    print("Color:", color)

Output:

1
2
3
4

Color: red
Color: blue
Color: green
Color: yellow

Using enumerate:

1

# Loop with index using enumerate
for index, color in enumerate(colors):
    print(f"Color at index {index} is {color}")

Output:

1
2
3
4

Color at index 0 is red
Color at index 1 is blue
Color at index 2 is green
Color at index 3 is yellow
