Numbers
Python has three main numeric types: int, float, and complex.
Example
a = 10 # int
b = 3.5 # float
c = 2 + 3j # complex
print(a + b)
print(c.real, c.imag)
Arithmetic
Example
x = 17
y = 5
print(x + y) # 22
print(x - y) # 12
print(x * y) # 85
print(x / y) # 3.4 (true division)
print(x // y) # 3 (floor division)
print(x % y) # 2 (remainder)
print(x ** y) # 1419857 (power)
