Python3 excellent parsing operator and python3 excellent Operator

Arithmetic Operators
+: Add two objects.
-: Get a negative number or, or a number minus another number.
*: Multiply two numbers or return a string that has been repeated for several times.
/: 5/2 equals 2.1 5 // 2 = 2 (/has the remainder, // get the integer)
%: Modulo (5% 2 = 1)
**: The power of 10 (10 ** 21) to the power of 21
Comparison (relational) Operator
=: (1 = 2) compare whether the object is equal. True is returned correctly. false is returned if an error occurs.
! = :( 1! = 2) compare whether two values are not equal
>:( 1> 2) returns false.
<: (1 <2) returns True.
>=: (1> = 2) false
<=: (1 <= 2) returns True.
Value assignment operator
=: A simple value assignment (a = B) assigns the value of B to
+ =: The addition and assignment operator c ++ = a is equivalent to c = c +.
-=: The subtraction and assignment operator c-= a is equivalent to c = c-.
* =: The multiplication and assignment operator c * = a is equivalent to c = c *.
/=: Division assignment operator c/= a is equivalent to c = c/
% =: Modulo value assignment operator c % = a is equivalent to c = c %
** =: The power assignment operator c ** = a is equivalent to c = c **
// =: The Division operator c // = a is equivalent to c = c //.
Logical operators
And: Multiple judgments can be spliced at the end. None of the errors will work (a and B)
Or: You can concatenate multiple judgments. If there is a pair, it is equal to (a or B)
Not: if it is correct, false is returned. True not (a and B) is returned if an error occurs)
Bitwise operators
&: Bitwise AND operator: the two values involved in the operation. If both corresponding bits are 1, the result of this bits is 1. Otherwise, it is 0.
(A & B) output result 12, binary explanation: 0000 1100
\: Bitwise OPERATOR: when only one of the two binary numbers is required to be 1, the result is 1.
(A \ B) output result 61, binary explanation: 0011 1101
^: Bitwise OR operator: When the binary phase of the two pairs is different, the result is 1.
(A ^ B) the output result is 49. Binary explanation: 0011 0001
~ : Bitwise anti-OPERATOR: returns the inverse of each binary bit of the data. That is, 1 is changed to 0, and 0 is changed to 1.
(~ A) the output result is-61. Binary interpretation: 1100 0011 is in the complement form of a signed binary number.
<: Left Shift Operator: each binary of an operation number shifts several places left by <the number on the right specifies the number of digits to move,
High Discard, status completion (a <2) output result is 240, binary explanation: 1111 0000
>>: Right moving OPERATOR: Move all the binary numbers on the left to several places on the Right> number on the right to the specified number of digits on the right
(A> 2) output result 15, binary explanation: 0000 1111
Member Operators
In: returns True if the value is found in the specified sequence. Otherwise, false is returned.
Not in: If no value is found in the specified sequence, True is returned; otherwise, false is returned.
Identity Operators
Is: determines whether two identifiers reference an object x is y similar to id (x) = id (y)
Is not determines whether two identifiers reference different objects. x is not y is similar to id (x )! = Id (y)
Operator priority
All operators with the highest to lowest priority are listed below
1: ** index (highest priority)
2 :~ +-Bitwise inversion, one-dollar plus sign and minus sign (the last two methods are named + @ and -@)
3: */% // multiplication, division, modulo and Division
4: +-addition and subtraction
5: >>< <shift right to the left Operator
6: & bit and
7: ^ \ bit operator
8: <=<>= comparison operator
9: <>=! = Equals Operator
10: = % = // =-= + = * = ** = value assignment operator
11: is not identity Operator
12: in not in member Operator
13: not or and logical operators
