Python Data Types – Numbers
Number data types store numeric values. They are immutable data types, which means that changing the value of a number data type results in a newly allocated object.
There are three numeric types in Python:
1. int
2. float
3. complex
Variables of numeric types are created when you assign a value to them.
Example:
a = 123 # int
b = 12.3 # float
c = 123j # complex
We use type() function to verify the type of any object in Python.
Example:
print(type(a))
print(type(b))
print(type(c))
1. int
int, or integer, is a whole number, positive or negative, without decimals, of unlimited length (In Python, there is no limit to how long an integer value can be).
Example 1:
a = 1
b = 9871234561
c = -7687543
print(type(x))
print(type(y))
print(type(z))
Example 2: Performing arithmetic Operations on int type
a = 10
b = 5
# Addition
c = a + b
print(“Addition:”, c)
d = 20
e = 10
# Subtraction
f = d – e
print(“Subtraction:”,f)
g = 12
h = 3
# Division
i = g // h
print(“Division:”,i)
j = 3
k = 5
# Multiplication
l = j * k
print(“Multiplication:”,l)
m = 25
n = 5
# Modulus
o = m % n
print(“Modulus:”,o)
p = 6
q = 2
# Exponent
r = p ** q
print(“Exponent:”,r)
Output:
Addition: 15
Subtraction: 10
Division: 4
Multiplication: 15
Modulus: 0
Exponent: 36
2. float
float, or “floating-point number” is a number, positive or negative, containing one or more decimals.
Example:
a = 1.14
b = 12.1
c = -35.59
print(type(a))
print(type(b))
print(type(c))
float can also be scientific numbers with an “e” to indicate the power of 10.
Example:
x = 35e3
y = 12E4
z = -87.7e100
print(type(x))
print(type(y))
print(type(z))
Example : Performing arithmetic Operations on float type
a = 5.5
b = 3.2
# Addition
c = a + b
print(“Addition:”, c)
# Subtraction
c = a-b
print(“Subtraction:”, c)
# Division
c = a/b
print(“Division:”, c)
# Multiplication
c = a*b
print(“Multiplication:”, c)
Output:
Addition: 8.7
Subtraction: 2.3
Division: 1.71875
Multiplication: 17.6
3. complex
complex numbers are written with a “j” as the imaginary part.
Example:
a = 3+5j
b = 5j
c = -5j
print(type(a))
print(type(b))
print(type(c))
