Data types in python

In this article, we will discuss about data types in python

What are data types?

Data is classified into different categories like integer, decimal, string etc. Each category is a data type.

Different types of data

   1. Integer – Any value that is

      a. A number

      b. Positive or negative

      c. Does not contain decimal.

PositiveValue = 25
NegativeValue = -12

   2. Float – Any value that is

      a. A number

      b. Positive or negative

      c. Contains decimal

PositiveValue  = 40000.35
NegativeValue  = -40000.35

3. String – It is the sequence of characters.

message = "Hello world"

A string can start with single and double quotes

string_with_single_quotes = 'value 1'
string_with_double_quotes = "value 2"

4. Boolean – This data type has 2 permissible values i.e. true or false

isFlag = True

How to access string variables?

Consider the following example

message = "Hello"
print(message[0])
print(message[1])
print(message[2])
print(message[3])
print(message[4])

Here string is accessible using index. Here is the output of the above program

Escape characters in string

Python supports multiple escape characters but we will discuss about only 2.

1. \n – Insert new line between the string.

2. \t – Insert tab space between the string.

Let us demonstrate it with an example.

message1 = "Hello \n world"
message2 = "Hello \t world"

print ("message1 is :", message1)
print ("message2 is :", message2)

Here is the output
