Python operator Four

This is the content of the December plan, beginning in January 2018 ~

If there is any mistake, please ask for it ~

This thing is actually very similar, choose a few special. Also, Python has no ++,--.

Just two, take a look.

**	Power-Returns the Y power of X	A**b is 10 of the 21-time Square
//	Divide-Returns the integer part of the quotient	9//2 output result 4, 9.0//2.0 output 4.0

1 Print (A) 2 Print (1.0/2) 3 Print (5//2) 4 Print (2**3)

python logical operators

and	X and Y	Boolean "and"-if x is False,x and y returns FALSE, otherwise it returns the computed value of Y.	(A and B) returns 20.
Or	X or Y	Boolean "or"-if x is True, it returns the value of x, otherwise it returns the computed value of Y.	(A or B) returns 10.
Not	Not X	Boolean "Non"-returns False if X is True. If X is False, it returns TRUE.	Not (A and B) returns False

python identity operator

operator	Description	Example
Is	is to determine whether two identifiers are referenced from an object	x is y, similar to ID (x) = = ID (y) , returns True if the same object is referenced, otherwise False
is not	Is does not determine whether two identifiers are referenced from different objects	x is not y, similar to ID (a)! = ID (b). Returns True if the reference is not the same object, otherwise False is returned.

The return value of the ID method is the memory address of the object.
