Operators

Arithmetic, comparison, logical, and assignment operators in Python.

Arithmetic Operators

+ (addition), - (subtraction), * (multiplication)
/ (division), // (floor division), % (modulus)
** (exponentiation)

x = 10
y = 3

print(x + y)   # 13
print(x - y)   # 7
print(x * y)   # 30
print(x / y)   # 3.333...
print(x // y)  # 3 (floor division)
print(x % y)   # 1 (remainder)
print(x ** y)  # 1000 (10^3)

Comparison Operators

== (equal), != (not equal)
> (greater), < (less)
>= (greater or equal), <= (less or equal)
Return True or False

a = 5
b = 10

print(a == b)  # False
print(a != b)  # True
print(a < b)   # True
print(a > b)   # False
print(a <= 5)  # True
print(b >= 10) # True

Logical Operators

and: Both conditions must be True
or: At least one condition must be True
not: Reverses the boolean value

x = 5
y = 10

print(x > 0 and y > 0)   # True
print(x > 10 or y > 5)   # True
print(not(x > 10))       # True

# Combining conditions
age = 20
if age >= 18 and age < 65:
    print("Working age")

Assignment Operators

= (assign), += (add and assign), -= (subtract and assign)
*= (multiply and assign), /= (divide and assign)
Shorthand for common operations

x = 10

x += 5   # Same as: x = x + 5
print(x) # 15

x -= 3   # Same as: x = x - 3
print(x) # 12

x *= 2   # Same as: x = x * 2
print(x) # 24

x /= 4   # Same as: x = x / 4
print(x) # 6.0
