Answer:
Logical Operators in Python are used to perform logical operations on the values of variables.
Arithmetic Operators
Arithmetic Operators perform various arithmetic calculations like addition, subtraction, multiplication, division, %modulus, exponent, etc. There are various methods for arithmetic calculation in Python like you can use the eval function, declare variable & calculate, or call functions.
Example: For arithmetic operators we will take simple example of addition where we will add two-digit 4+5=9
x= 4
y= 5
print(x + y)
Similarly, you can use other arithmetic operators like for multiplication(*), division (/), substraction (-), etc.
Comparison Operators
Comparison Operators in Python compares the values on either side of the operand and determines the relation between them. It is also referred to as relational operators. Various comparison operators in python are ( ==, != , <>, >,<=, etc)
Example: For comparison operators we will compare the value of x to the value of y and print the result in true or false. Here in example, our value of x = 4 which is smaller than y = 5, so when we print the value as x>y, it actually compares the value of x to y and since it is not correct, it returns false.
x = 4
y = 5
print(('x > y is',x>y))
Likewise, you can try other comparison operators (x < y, x==y, x!=y, etc.)
Python Assignment Operators
ASSIGNMENT OPERATORS in PYTHON are used for assigning the value of the right operand to the left operand. Various assignment operators used in Python are (+=, - = , *=, /= , etc.).
Example: Python assignment operators is simply to assign the value, for example
num1 = 4
num2 = 5
print(("Line 1 - Value of num1 : ", num1))
print(("Line 2 - Value of num2 : ", num2))
Example of compound assignment operator
We can also use a compound assignment operator, where you can add, subtract, multiply right operand to left and assign addition (or any other arithmetic function) to the left operand.
Step 1: Assign value to num1 and num2
Step 2: Add value of num1 and num2 (4+5=9)
Step 3: To this result add num1 to the output of Step 2 ( 9+4)
Step 4: It will print the final result as 13
num1 = 4
num2 = 5
res = num1 + num2
res += num1
print(("Line 1 - Result of + is ", res))
Logical Operators
Logical operators in Python are used for conditional statements are true or false. Logical operators in Python are AND, OR and NOT. For logical operators following condition are applied.
For AND operator – It returns TRUE if both the operands (right side and left side) are true
For OR operator- It returns TRUE if either of the operand (right side or left side) is true
For NOT operator- returns TRUE if operand is false
Example: Here in example we get true or false based on the value of a and b
a = True
b = False
print(('a and b is',a and b))
print(('a or b is',a or b))
print(('not a is',not a))
Membership Operators
These operators test for membership in a sequence such as lists, strings or tuples. There are two membership operators that are used in Python. (in, not in). It gives the result based on the variable present in specified sequence or string
Example: For example here we check whether the value of x=4 and value of y=8 is available in list or not, by using in and not in operators.
x = 4
y = 8
list = [1, 2, 3, 4, 5 ];
if ( x in list ):
print("Line 1 - x is available in the given list")
else:
print("Line 1 - x is not available in the given list")
if ( y not in list ):
print("Line 2 - y is not available in the given list")
else:
print("Line 2 - y is available in the given list")
Declare the value for x and y
Declare the value of list
Use the "in" operator in code with if statement to check the value of x existing in the list and print the result accordingly
Use the "not in" operator in code with if statement to check the value of y exist in the list and print the result accordingly
Run the code- When the code run it gives the desired output
