Data types in Python

Welcome Friends,

Before we begin our programming, let's get used to with the various basic data types. 

1.    Integer (int): It takes the whole number including negative values for example 0, 1, 2, 3 etc as well as a negative number like -1, -2, -3, ...

If you notice, when we added these two number, it simply concatenated the numbers. We first need to convert these numbers into strings and then add it.

2.    Float (float): It can take decimal values, for example, 3.14, 7.99, 15.23 etc.

3.    String (str): It is a sequence of characters, for example, "Hello", "Welcome to Python world"

Note: you can assign a string variable in either single quotes (like ‘Hello’) or double quotes (like “Hello”)

4.    Boolean: It takes only two values, i.e. True or False

5.    List: It is a collection of objects or values. It is denoted by []

To add, use the command, append

To remove an element from the list using the keyword remove

6.    Tuple: It is similar to list but once it is created it cannot be changed and it is denoted in the () bracket.

7.    Dictionary (dict): It is used to store data in key-value pair and it is stored in {}

Hope, now we can get some basics with the data types and in our next blog, we will write some simple programs. Stay tuned.
