Download as pptx, pdf0 likes212 views
This document discusses different types of operators in Python including arithmetic, comparison, assignment, logical, membership, and identity operators. It provides examples of using arithmetic operators like addition, subtraction, multiplication, division, floor division, exponentiation, and modulus on variables. It also covers operator precedence and use of operators with strings.
![Arithmetic Operators
Arithmetic operators are used with numeric values to perform common
mathematical operations:
Operator Name Example
+ Addition x + y
- Subtraction x - y
* Multiplication x * y
/ Division x / y
// Floor division[Integer Division] x // y
** Exponentiation x ** y
% Modulus x % y](https://image.slidesharecdn.com/pythonoperator1-200924134057/85/OPERATOR-IN-PYTHON-PART1-3-320.jpg)
![Arithmetic Operators
Example 1:
A=27
B=5
C=A/B
print(“A/B=“,C)
--Output---
A/B=5.4
Example 2:
A=27
B=5
--Output---
A//B=5
/ [Division] x / y // Floor division[Integer Division] x // y
C=A//B
print(“A//B=“,C)](https://image.slidesharecdn.com/pythonoperator1-200924134057/85/OPERATOR-IN-PYTHON-PART1-7-320.jpg)
![Arithmetic Operators
Example 1:
A=27
B=5
C=A%B
print(“A%B=“,C)
--Output---
A%B=2
Example 2:
A=int(input(“Enter the value of A:”))
--Output---
Enter the value of A: 4
Enter the value of B: 2
A%B=0
% [Modulus] x % y : It return remainder value
C=A%B
print(“A%B=“,C)
B=int(input(“Enter the value of B:”))](https://image.slidesharecdn.com/pythonoperator1-200924134057/85/OPERATOR-IN-PYTHON-PART1-8-320.jpg)

- 10. Precedence of Arithmetic Operators Highest Lowest () parentheses ** (Exponentiation) /(division) // (integer division) * ( multiply) % (modulas) + (addition) - ( subtraction)
- 11. Expressions: An expression is a combination of variable and operators. It generates a single value, which by itself is an expression. Example: 5 + 2 * 4 and the result is 13 Q. Convert the Mathematical Expressions to equivalent python expressions Algebraic Expression Python Programming Expression 5A 5 * A 4ab 4 * a * b A2 + B2 A**2 + B **2 a=(x+y)/(x-y)
- 12. 20 + 30 * 40 Evaluate the expressions: 1 2 20 + 120 140 20 - 30 + 40 1 2 -10 + 40 30 The two operators (–) and (+) have equal precedence. Thus, the first operator, i.e., subtraction is applied before the second operator, i.e., addition (left to right).
- 13. Evaluate the expressions: 12 + 3 * 4 – 6/2 1 3 4 12 + 12 – 6/2 12 + 12 – 3.0 2 24– 3.0 21.0 (12 + 3) * 4 – 6//2 1 2 4 3 15 * 4 – 6//2 60 – 6//2 60 – 3 57
- 14. + ( plus) and (*) sign for string + ( plus) : It is use to concatenation of string and in string case + (plus) sign is known as concatenation operator. Example: If there are two variable A=‘WELCOME’ and B=‘PYTHON’ and we want to join these two strings. A=‘WELCOME’ B=‘PYTHON’ print(A+B) ---Output---- WELCOMEPYTHON It display join or concatenation of two string but without any gap
- 15. + ( plus) and (*) sign for string * (multiply) : It is use to repeat the string as many times we need by multiplying the string with number given. Example: If variable A=‘WELCOME’ and we want to display WELCOME 3 times A=‘WELCOME’ print(A*3) ---Output---- WELCOMEWELCOMEWELCOME
