int: whole numbers of unlimited size, e.g. 42, -7.float: decimals, e.g. 3.14, 2.5e3.complex: e.g. 3 + 5j.Convert between them with int(), float() and complex(). The random module creates random numbers.
Mastering Python Numbers helps you write clean and reliable Python code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.
import random
big = 2 ** 100
print("Big int:", big)
print("Float:", 7 / 2, "Integer division:", 7 // 2)
print(int(9.99), float(5), round(3.14159, 2))
print("Random 1-6:", random.randint(1, 6))Check what you learned in “Python Numbers”.
