x=10
x+=20
print ("The x + = 20 is =",x)
x-=5
print ("The x -= 5 is = ",x)
x*=5
print ("The x *= 5 is = ",x)

1.
All data values in Python are objects and each object or value has a type. Python has Built-in or fundamental data types such as Number, String, Boolean, tuples, lists, and dictionaries.
1. Number data types
The built-in number objects in Python supports integers, floating-point numbers and complex numbers.
Integer Data can be decimal, octal or hexadecimal. Octal integer use O (both upper and lower case) to denote octal digits and hexadecimal integer use Ox (both upper and lower case) and L (only upper case) to denote long integer.
Example
702,4567,567 #Decimal integers
O102, 0876, O432 #Octal integers
Ox102, Ox876, Ox432 #Hexadecimal integers
34L, 523 L #Longdecimal integer
A floating-point data is represented by a sequence of decimal digits that includes a decimal point. An Exponent data contains a decimal point, exponent part followed by one or more digits.
Example
123.34,456.23,156.223 #Floating point data
12. E04, 21.e04 #Exponent data
A complex number is made up of two floating-point values, one each for the real and imaginary parts.
2. Boolean Data type
A Boolean data can have any of the two values: True or False.
Example
Bool_var 1 = True
Bool_var 2 = False
3. String Data type
String data can be enclosed with a single quote or double quote or triple quote.
Example
char-data = 'A'
srting_data = " Computer Science"
Multi_data = """" String data can be enclosed with a single quote or double quote or triple quote."""
2.
Type a Value for X : 10
The x + = 20 is = 30
The x - = 5 is = 25
The x * = 5 is = 125
The x / = 2 is = 62.5
The x % = 3 is = 2.5
The x ** = 2 is = 6.25
The x// = 3 is = 2.0
