1. Integer Data Type: In this type, we take up the whole number, and it can be of any length
Input
#Integer values always take whole values
value_1 = int(input('Enter first whole number:'))
value_2 = int(input('Enter second whole number:'))
add = value_1 + value_2
# print() gives permanent output
print('Addition of 2 integer value {} and {} is {}'.format(value_1,value_2,add))
# type() tells in which class a variable belongs to
print(add,'is type of', type(add))
Output
Enter first whole number:8500
Enter second whole number:1200
The addition of 2 integer value 8500 and 1200 is 9700
9700 is type of <class 'int'>
2. Float data type - In this type, we take up decimal values and give accurate values up to 15 decimal places.
Input
a = 12.1564897123654789
print(a,'is a decimal value upto place 15')
print(a,'is a type of',type(a))
# isinstance() tells particular value belongs to that class or not
print(a,'is float number? ',isinstance(a,float))
Output
12.15648971236548 is a decimal value up to place 15
12.15648971236548 is a type of <class 'float'>
12.15648971236548 is the float number? True
we can see in our float number as 9 is truncated
3. Complex Data type: Complex numbers make with the real and the imaginary parts i.e a+bj. For the imaginary part, we use 'j' in python.
Input
num = 12 + 4j
print(num,'is belong to',type(num))
print(num,'is a complex number?', isinstance(num,complex))
Output
(12+4j) is belong to <class 'complex'>
(12+4j) is a complex number? True
4. Boolean Data Type: It always takes up True(1) or False(0) values and gives output either 1 or 0. Let's see by the example
Input
a = True
b = False
print(a,b,'belong to',type(a),type(b))
print('sum and multiplication of boolean values {},{} are : '.format(a,b),a+b,'and',a*b)
print('Type of sum and multiplication is',type(a+b),type(a*b))
Output
True False belong to <class 'bool'> <class 'bool'>
sum and multiplication of boolean values True,False are : 1 and 0
Type of sum and multiplication is <class 'int'> <class 'int'>
here we can see class of sum and multiplication is integer.
5. String Data Type: String literals can be defined with any of single quotes ('), double quotes (") or triple quotes (''' or """). All give the same result with two important differences.
If you quote with single quotes, you do not have to escape double quotes and vice-versa. If you quote with triple quotes, your string can span multiple lines
Input
string = 'Hello Python'
print(string,'belongs to',type(string))
# Parsing the string by using index number
print('First letter of word =',string[0])
#start(0) :end(5-1) : step size(2) always exclude upper bound means gives output till index no:UB-1
print('Desired result with step size 2 =',string[0:5:2])
# Reverse the string
print('Reverse the given string = ', string[::-1])
# multiple lines
"""print("fsdfsdfs)
(FsdfsfsFSDFSAFASFASDDF)
(sdfsfsdf")"""
Output
Hello Python belongs to <class 'str'>
The first letter of word = H
The desired result with step size 2 = Hlo
Reverse the given string = nohtyP olleH
'print("fsdfsdfs)\n(FsdfsfsFSDFSAFASFASDDF)\n(sdfsfsdf")'
