-a #Negation¶
a + b #Addition¶
a - b #Subtraction¶
a * b #Multiplication¶
a / b #Division. In Python 2.x, when both arguments are integers, the result is always an integer,¶
# rounding down (toward negative infinity, not 0) when the numbers do not divide evenly.¶
# In Python 3.x, when integers do not evenly divide, the result is a float¶
a // b #Truncating Division. Always rounds down to the nearest integer, regardless of argument types¶
a % b #Modulus. Python's modulus takes the sign of "b", unlike PHP's, which takes the sign of "a"¶
