How did Python Numbers work?

Python In Numbers:

There are three numeric types in python which handle different mathematical calculations through the data.

  • Int [Integer]
  • float [Float]
  • complex

Then variables are numeric types created when assign on data on it. Like,

x = 16    # int
y = 2.48  # float
z = 10j   # complex

So to verify the type of each variable we use type() function,

x = 1
y = 2.8
z = 1j

print(type(x));
print(type(y));
print(type(z));
#Output
<class 'int'>
<class 'float'>
<class 'complex'>

Int:

The int, or integer, is a whole number or natural numbers, positive or negative, without decimals, and unlimited length.

x = 1
y = 356567775548877
z = -3377722

print(type(x))
print(type(y))
print(type(z))

The output of above code,

#Output
<class 'int'>
<class 'int'>
<class 'int'>

Float:

The float or floating-point is a number, is a positive or negative number, without decimals, of unlimited length.

x = 1.10
y = 1.0
z = -35.59

print(type(x))
print(type(y))
print(type(z))

The output of above code,

<class 'float'>
<class 'float'>
<class 'float'>

The float has scientific numbers ‘e’ to indicate the power of 10.

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

print(type(x))
print(type(y))
print(type(z))

The output of above code,

#Output
<class 'float'>
<class 'float'>
<class 'float'>

Complex:

The Complex numbers are written with a alphabet “j” as called as imaginary part:

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

print(type(x))
print(type(y))
print(type(z))

The output of above code,

#Output
<class 'complex'>
<class 'complex'>
<class 'complex'>

Type Conversion:

In type conversion to convert from one type to another we use int()float(), and complex() methods:

#Convert from one type to another:
x = float(10)

#convert from float to int:
y = int(2.80)

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

print(x)
print(y)
print(z)

print(type(x))
print(type(y))
print(type(z))

The output of above code,

#Output:
1.0
2
(1+0j)
<class 'float'>
<class 'int'>
<class 'complex'>

You can’t convert complex number to any other number type.

Random Number:

Python doesn’t have a random() function to make a random number, but python has built-in module called random that can be used to make random numbers.

#Import inbuilt random to display random numbers Form 1 to 9
import random

print(random.randrange(1, 10))

The output of above code,

#Output:
9
