Python Number

Integers in python programming

Python supports integers. The integers are numbers such as -1, 0, 1, 2, and 3. In python int is the data type of integer number. You can create mathematical operation with integer values. You can use +,-,*,/,exponents(**).

Program

a = 20
b = 10
sum = a + b
sub = a - b
mul = a * b
div = a / b
exp = a ** b
print(sum)
print(sub)
print(mul)
print(div)
print(exp)

Float in python programming

Python supports floats numbers. Any number with a decimal point is a floating-point number. example 5.24, 25.45, 50.89. Data type of floating number is float.

You can create mathematical operation with integer values. You can use +,-,*,/,exponents(**).

Float can also be scientific numbers with an "e" to indicate the power of 10.

Program

a = 1.10
b = 1.0
c = -35.59
d = 35e3
e = 12E4
f = -87.7e100
print(type(a))
print(type(b))
print(type(c))
print(type(d))
print(type(e))
print(type(f))

Underscores in numbers

When a number is large, it’ll become difficult to read. For example: 35656222554887711. You can make the long numbers more readable. You can group digits using underscores like 35_656_222_554_887_711. The underscores also work for both integers and floats.

Program

a = 35_656_222_554_887_711
b = 45.656_333_554_887_222
print(a)
print(b)

Complex in python programming

Complex numbers are written with a "j" as the imaginary part.

Program

a = 3+5j
b = 5j
c = -5j
print(type(a))
print(type(b))
print(type(c))

Random number in python

Program

import random
print(random.randrange(1, 10))
