🐍 Python Basics 6/6: Tricks and Bonuses

0) Swapping Variables Values

a = 3
b = 4
a, b = b, a

print(f"a: {a}")
print(f"b: {b}")

1) Declaring Variables with Same Values

a = b = c = 5
print(f"a: {a}\tb: {b}\tc: {c}")

a = 2
print(f"a: {a}\tb: {b}\tc: {c}")

2) Null Value

a = None
print(a)

3) Deleting Variables from Memory

a = 5
print(f"a: {a}")

del a
print(f"a: {a}")

4) Reversing a String

my_string = "What's shaking, guys?"
my_reversed_string = my_string[::-1]

print(f"String: {my_string}")
print(f"Reversed String: {my_reversed_string}")

5) Ordering Lists

my_list = [5, 83, 8, 1, 3, 90, 28, 75, 6]
print(f"List: {my_list}")

my_list.sort()
print(f"Sorted List: {my_list}")
