Python Numbers :

Python Numbers :

Number data types store numeric values. They are immutable data types, 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

Example :

  1. x = 1
  2. y = 4.8
  3. z = 1j
  4. print("python number types :\n")
  5. print(type(x))
  6. print(type(y))
  7. print(type(z))
  8. input()

Output :

python number types

Note : To verify the type of any object in Python, use the type() function.


int :

int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.

Example :

  1. x = 1
  2. y = 11796348708246
  3. z = -77885522
  4. print(type(x))
  5. print(type(y))
  6. print(type(z))
  7. input()

Output :

python int numbers

float :

float, or "floating point number" is a number, positive or negative, containing one or more decimals.

Example :

  1. x = 2.0
  2. y = 10.50
  3. z = -50.80
  4. print(type(x))
  5. print(type(y))
  6. print(type(z))
  7. input()

Output :

python float numbers

complex :

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

Example :

  1. x = 4+10j
  2. y = 7j
  3. z = -15j
  4. print(type(x))
  5. print(type(y))
  6. print(type(z))
  7. input()

Output :

python complex numbers
