Creating Simple Lists

Now that you know the syntax of list comprehensions, let’s dive into some simple examples to see how they can be used to create new lists quickly and efficiently.

Create a list of cube numbers:

cubes = [x**3 for x in range(1, 6)]
print(cubes)
# Output: [1, 8, 27, 64, 125]

Create a list of strings from characters:

chars = [char for char in "hello"]
print(chars)
# Output: ['h', 'e', 'l', 'l', 'o']

Generate a list of even numbers:

evens = [x for x in range(2, 11, 2)]
print(evens)
# Output: [2, 4, 6, 8, 10]

Convert all items in a list to uppercase:

words = ["apple", "banana", "cherry"]
uppercase = [word.upper() for word in words]
print(uppercase)
# Output: ['APPLE', 'BANANA', 'CHERRY']

List comprehensions make it easy to work with sequences, apply transformations, and even include conditions—all in one line!
