An operator is a special symbol that is used to perform some operations in a Python program. An operator generally requires some variables, known as operands, to operate upon.

Python provides us with the number of operators.

Operators can be unary or ternary. Unary operator requires a single operand to operate upon. Ternary operator requires two or more operators to operate upon. Further moving on, we can classify operators into various parts :

1. Arithmetic Operators
2. Assignment Operators
3. Relational Operators
4. Logical Operators
5. Bitwise Operators
6. Membership Operators
7. Identity Operators

1. Arithmetic Operators

num1 = 20
num2 = 10

# Working with Arithmetic Operators

print("num1 + num2 = ", num1+num2)
print("num1 - num2 = ", num1-num2)
print("num1 * num2 = ", num1*num2)
print("num1 / num2 = ", num1/num2)
print("num1 // num2 = ", num1//num2)
print("num1 % num2 = ", num1%num2)
print("num1 ** num2 = ", num1**num2)

2. Assignment Operators

# Working with Assignment Operators
num = 10
print("num = ", num)
num += 5
print("num += 5 = ", num)
num -= 5
print("num -= 5 = ", num)
num *= 5
print("num *= 5 = ", num)
num /= 5
print("num /= 5 = ", num)
num //= 5
print("num //= 5 = ", num)
num **= 5
print("num **= 5 = ", num)
num = 5
num &= 5
print("num &= 5 = ", num)
num |= 5
print("num |= 5 = ", num)

3. Relational/ Comparison Operator

num1 = 20
num2 = 10

# Working with Relational Operators

print("num1 < num2 = ", num1<num2)
print("num1 > num2 = ", num1>num2)
print("num1 == num2 = ", num1==num2)
print("num1 >= num2 = ", num1>=num2)
print("num1 <= num2 = ", num1<=num2)
print("num1 != num2 = ", num1!=num2)

4. Logical Operator

condition1 = False
condition2 = True

# Working with Logical Operators

print("condition1 and condition2 = ", condition1 and condition2)
print("condition1 or condition1 = ", condition1 or condition2)
print("not condition1 = ", not condition1)

5. Bitwise Operator

num1 = 20
num2 = 10

# Working with Bitwise Operators

print("num1 | num2 = ", num1|num2)
print("num1 ^ num2 = ", num1^num2)
print("num1 & num2 = ", num1&num2)
print("num1 << num2 = ", num1<<num2)
print("num1 >> num2 = ", num1>>num2)
print("~ num2 = ", ~num2)

6. Membership Operators

list1 = [2, 5, 6, 7]
n = 5
if n in list1:
    print("Number present in list")
elif n not in list1:
    print("Number not present in list")

7. Identity Operators

num1 = 10
num2 = 10
num3 = 20
if num1 is num2:
    print("num1 is num2")
if num1 is not num3:
    print("num1 is not num3")

That’s all, see you in the next lecture.
