Python operators

Python has the some numeric operators that you would expect; note that the truncating division, (//, also known as floor division) truncates the result to an integer and a floating point and return the integer value. The integer value is returned. The modulo (%) operator returns the remainder value in the division:

    >>> 1 + 2    3    >>> 2 - 1    1    >>> 1 * 5    5    >>> 5 / 1    5.0    >>> 5 // 2    2    >>> 5 % 2    1

There are also comparison operators:

    >>> a = 1    >>> b = 2    >>> a == b    False    >>> a > b    False    >>> a < b    True    >>> a <= b    True 

We will also see two of the common membership operators to see whether an object is in a sequence type:

    >>> a = 'hello world'    >>> 'h' in a    True    >>> 'z' in a    False    >>> 'h' not in a    False    >>> 'z' not in a    True
