x = 3

x += 3 is the same as x = x + 3

x *= 3 is the same as x = x * 3

x /= 3 is the same as x = x / 3 and so on.

These are all assignment operators.

3. Python Logical Operators

Python logical operators can be used within a statement to combine conditional statements. For example:

a > 1 and a < 3 returns True if ‘a’ contains a value that is more than 1 and less than 3.

a < 1 or a > 3 returns True if ‘a’ contains a value that is less than 1 or more than 3.

not(a > 1 and a < 3) returns True if ‘a’ contains a value that is less than 1 or more than 3.

4. Python Comparison Operators

We can use Python comparison operators to compare two values. For example,

a == b compares whether a and b contain the same value

a < b compares whether a is less than b

a > b compares whether a is greater than b

a != b compares whether a contains a value that is different from b

Similarly, a >= b compares whether a is greater than or equal to b and so on.

5. Python Bitwise Operators

Python bitwise operators are used to perform bitwise operations on operands. For example,

a | b performs a bitwise or operation between a and b

a & b performs a bitwise and operation between a and b

~a inverts all bits of a

a ^ b performs a bitwise xor operation between a and b

a << 2 left shifts the value of a by 2 bits and the rightmost 2 bits are filled with zeros

a >> 2 right shifts the value of a by 2 bits and the leftmost 2 bits are filled with zeros
