Numbers and Boolean in Python

 

Numbers play an important role in our daily life either it’s about telling our age or dealing with payments. Same goes for our programs!

In programming, we have to deal with numbers either they are gaming scores or storing numerical information. Python has provided us with several ways to represent numeric data depending upon the nature of data. In the last article we have discussed string data type and the method of string You can check the article: https://www.codiuxtech.com/2020/12/primitive-data-types-in-python.html

 Now, Let’s explore the other data types one by one. First, we will look at how Python manages integers.

Integer:

Integers are both negative and positive whole numbers. We can add, subtract, multiply and divide the integers.

>>> print (3 + 4) >>> print (4 – 3) >>> print (3 * 4) >>> print (4 / 3)   Output: 7 1 12 1.33

 

In python, we need to use double multiplication signs for the exponent. Let’s take the example below to understand it.

>>> print (2**3) # 2x2x2 >>> print (3**2) # 3x3   Output: 8 9

Float:

Any number with the decimal point is called float number in python programming. Every mathematical operation that we can perform on integer can be executed on the float as well. The float can also represent the scientific number with an “e” to express the power of 10.

>>> print (3.5 + 4) >>> print (4.5 – 3.5) >>> print (22e3) >>> print (-23.45e100)   Output: 7.5 1.0 22000.0 -2.345e+101

 

These two are the primitive data types of number in python. Now let’s move to the next data type.

Boolean:

Boolean represents either of two values: True or False.

In programming, Booleans are used in the evaluation of an expression, comparison of two values and return type of a function. Let’s consider the following example to understand it:

>>> print (9 > 8) >>> print (3 == 2)   Output: True False

 

Take another example:

>>> def booleanFunction() : >>>     return True   >>> if booleanFunction(): >>>     print("YES!") >>> else: >>>      print("NO!")   Output: YES!

 

Any string, number, list, tuple, set and the dictionary is True except empty string, 0 and empty list, tuple, set and dictionary.
