Arithmetic Operators Notes

Arithmetic Operators Notes

Operator Example	Description
M + N	Addition of M and N
M – N	Subtraction of N from M
M * N	Multiplication of M and N
M / N	Division of M by N (The result will be a real number.)
M // N	Integer division of M by N (The result will be an integer.)
M % N	Modulo: find the remainder of M divided by N
M ** N	Exponentiation: M to the power of N (e.g., 2 ** 4 results in 16. 2*2*2*2=16

Note: Python also has the math module that contains common math functions (such as sin, cos, etc.)

Shortcut Operators

Operator Example	Description
M += N	M = M + N
M -= N	M = M – N
M *= N	M = M * N
M /= N	M = M / N
M //= N	M = M // N
M %= N	M = M % N

Boolean (or Logical) Operators

Operator Example	Description	Effect
A and B	AND	‘True’ if ‘A’, ‘B’ are both ‘True’; ‘False’ otherwise.
A or B	OR	‘True’ if either or both of A, ‘B’ are ‘True’. False if both A and B are false.
A == B	Equality	True if ‘A’ is equal to ‘B’.
A != B	Inequality	True if A is NOT equal to B.
NOT B	Negation	True if B is NOT True.
