Python Numbers
There are three numeric types in Python:

int
float
complex
Variables of numeric types are created when you assign a value to them:

Example
x = 1 # int
y = 2.8 # float
z = 1j # complex
To verify the type of any object in Python, use the type() function:

Example
print(type(x))
print(type(y))
print(type(z))
Int
Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.

Example
Integers:

x = 1
y = 35656222554887711
z = -3255522

print(type(x))
print(type(y))
print(type(z))
Float
Float, or "floating point number" is a number, positive or negative, containing one or more decimals.

Example
Floats:

x = 1.10
y = 1.0
z = -35.59

print(type(x))
print(type(y))
print(type(z))
Float can also be scientific numbers with an "e" to indicate the power of 10.

Example
Floats:

x = 35e3
y = 12E4
z = -87.7e100

print(type(x))
print(type(y))
print(type(z))
Complex
Complex numbers are written with a "j" as the imaginary part:

Example
Complex:

x = 3+5j
y = 5j
z = -5j

print(type(x))
print(type(y))
print(type(z))
Type Conversion
You can convert from one type to another with the int(), float(), and complex() methods:

Example
Convert from one type to another:

x = 1 # int
y = 2.8 # float
z = 1j # complex

#convert from int to float:
a = float(x)

#convert from float to int:
b = int(y)

#convert from int to complex:
c = complex(x)

print(a)
print(b)
print(c)

print(type(a))
print(type(b))
print(type(c))
Note: You cannot convert complex numbers into another number type.

Random Number
Python does not have a random() function to make a random number, but Python has a built-in module called random that can be used to make random numbers:

Example
Import the random module, and display a random number between 1 and 9:

import random

print(random.randrange(1, 10))
