Equal sign with vertical line. For example, and assuming a platform on which a Python float is an IEEE 754 double-precision number, in order that -1e-100 % 1e100 have the same sign as 1e100, the computed result is -1e-100 + 1e100, which is numerically exactly equal to 1e100. Python supports the usual logical conditions from mathematics: Equals: a == b Not Equals: a != b Less than: a < b Less than or equal to: a <= b Greater than: a > b Greater than or equal to: a >= b These conditions can be used in several ways, most commonly in … In the example below, we use the + operator to add together two values: Example.

This python operators evaluates if x and y are the same value and return the result as a boolean value. When it comes to objects, Python is not very strict about that and internally implements a set of rules to decide if an object is considered true or false: By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object.
