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
