Numbers Copy
The values stored by Number data types are Numeric values. Number objects are only valid when they are assigned values. For example:
var1=10
var2=50
In Python, there are four types of numerical types, i.e. int (signed integers), float (floating point real values) and complex (complex numbers).
Int
Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.
Example:
x = 1
y = 35656222554887711
z = -3255522
print(type(x))
print(type(y))
print(type(z))
Output:
<class ‘int’>
<class ‘int’>
<class ‘int’>
Float
Float, or “floating point number” is a number, positive or negative, containing one or more decimals. Float can also be scientific numbers with an “e” to indicate the power of 10.
Example:
x = 1.10
y = 1.0
z = -35.59
print(type(x))
print(type(y))
print(type(z))
Output:
<class ‘float’>
<class ‘float’>
<class ‘float’>
Complex
Complex numbers are written with a “j” as the imaginary part.
Example:
x = 3+5j
y = 5j
z = -5j
print(type(x))
print(type(y))
print(type(z))
Output:
<class ‘complex’>
<class ‘complex’>
<class ‘complex’>
