Summary

  • Integers are whole numbers that include negative whole numbers, zero, and positive whole numbers.
  • Computers use binary numbers to represent integers.
  • Python uses a variable number of bits to represent integers. Therefore, the largest integer number that Python can represent depends on the available memory of the computer.
  • In Python, all integers are instances of the class int.
  • Use the getsizeof() function of the sys module to get the number of bytes of an integer.
  • Python integers support all standard operations including addition, subtraction, multiplication, division, and exponent.
