Common Python Operator Mistakes and How to Use Them Correctly

Many beginners assume that the symbols ^, & and | in Python behave like exponentiation, logical AND, and logical OR respectively, which leads to incorrect results.

In Python these three symbols belong to the same class: bitwise operators . They first convert integers to binary and then perform logical operations on each bit.

Bitwise AND ( & ) returns 1 for a bit position only when both operands have 1 in that position. Example:

a = 3    # 0011
b = 5    # 0101
c = a & b    # 0001
print(c)   # 1

Bitwise OR ( | ) returns 1 when at least one operand has 1 in the bit position. Example:

a = 3    # 0011
b = 5    # 0101
c = a | b    # 0111
print(c)   # 7

Bitwise XOR ( ^ ) returns 1 when the bits differ. Example:

a = 3    # 0011
b = 5    # 0101
c = a ^ b    # 0110
print(c)   # 6

Python does not have a dedicated “power” symbol; exponentiation is performed with **. For instance, the area of a circle should be calculated as s = 3.14 * (r ** 2), not with r ^ 2.

Logical conjunction and disjunction are expressed with the keywords and and or, not with & or |.

In everyday Python development bitwise operators appear rarely, but understanding their correct meaning helps avoid subtle bugs when they are needed.
