Working with lists

Iterating through a list

magicians = ['alice', 'david', 'Carolina']
for magician in magicians:
    print(magician)

Numerical Lists

for value in range(1, 5):
    # inclusive will not include the last value in a range
    print(value)

Even Lists

#Starts at 2 and increments by 2 until it reaches or passes the final numbers that being 11
for value in range(2, 11, 2):
    print(value)

Square Lists

squares = []
for value in range(1, 11):
    square = value**2
    squares.append(square)

print(squares)

Statistics Lists

digits = [1,2,3,4,5,6,7,8,9,10]
print(min(digits))
print(max(digits))
print(sum(digits))

List Comprehension

List comprehension combines the for loop and the creation of new elements into one line, and automatically appends each new element.

Squares comprehension

squares = [value**2 for value in range(1, 12)]
print(squares)

Slicing A list

# [0:3] would return the elements from the indices 0 to 2
# [:3] Can also be omitted
# [0:] Given start value to end
players = ['adam', 'atom', 'atem', 'ahtam']
print(players[0:3])

Slicing and Looping

players = ['adam', 'atom', 'atem', 'ahtam']
for player in players[:-1]:
    print(player)
print("")

for player in players[:3]:
    print(player)
print("")

for player in players[::-1]:
    print(player)

Copying a list

my_foods = ['Pizza', 'falafel', 'carrot cake']
friends_food = my_foods[:] 
print(my_foods)
print(friends_food)
