This article mainly introduces "what Python operators are there". In daily operation, I believe many people have doubts about what Python operators are there. Xiaobian consulted all kinds of information and sorted out simple and easy operation methods. I hope to help you answer the doubts about "what Python operators are there"! Next, please follow the small series to learn together!

basic assignment operator

= is Python's most common and basic assignment operator, used to assign the value of an expression to another variable.

An assignment expression in Python also has a value, and its value is the value assigned to it, or the value of the variable on the left; if the value of the assignment expression is assigned to another variable, this constitutes a continuous assignment.

Note:

= and == are two different operators,= is used to assign values, and == is used to determine whether the values on both sides are equal. Don't confuse them.

= can also be combined with other operators (including arithmetic, bitwise, and logical operators) to expand into more powerful assignment operators, as shown in the following table:

The operator illustrates the usage example equivalent form = the most basic assignment operation x = yx = y+= add assignment x += yx = x + y-= subtract assignment x -= yx = x - y*= multiply assignment x *= yx = x * y/= divide assignment x /= yx = x / y%= take remainder assignment x %= yx = x % y**= power assignment x **= yx = x ** y//= take integer assignment x //= yx = x //y&= bitwise and assigned x &= yx = x & y| = bitwise or assigned x| = yx = x |y^= bitwise exclusive OR assignment x ^= yx = x ^ y> y, where y refers to the right-shifted bitwise digit operator

Python bitwise operators can only be used to manipulate integer types, and they evaluate integers in binary form in memory. Python supports the following bitwise operators:

bitwise operator description use form example & bitwise with a & b 4 & 5| bitwise a| b4 |5^bitwise exclusive OR a ^ b4 ^ 5~ bitwise negation ~a~4 b4 >> 2, representing integer 4 bitwise right shift 2 bits & bitwise AND operator

The bitwise AND operator & operates according to the rule that the result is 1 only if both bits involved in the & operation are 1, otherwise it is 0. For example, 1&1 is 1, 0&0 is 0, and 1&0 is also 0, which is very similar to the logical operator &&.

First Bit Second Bit Result 000010100111| bitwise OR operator

bitwise OR operator| The rule of operation is: when one of the two binary bits is 1, the result is 1, and when both bits are 0, the result is 0. e.g., 1| 1 for 1, 0| 0 is 0, 1| 0 is 1, which is the same as in logical operations.|| Very similar.

First Bit Second Bit Result 00011101111 ^Bitwise XOR operator

The bitwise exclusive-OR operation ^follows the rule that if the two binary bits involved in the operation are different, the result is 1, and if they are the same, the result is 0. For example, 0^1 is 1, 0^0 is 0, and 1^1 is 0.

First Bit Second Bit Result 00011101110 ~ Bitwise Negation Operator

The bitwise negation operator ~ is a monocular operator (with only one operand), right associative, which negates the binary bits involved in the operation. For example,~1 is 0,~0 is 1, which is the same as the logical operation! Very similar.

Used to shift all binary bits of the operand to the right by a number of bits, discarding the low bits and filling the high bits with 0 or 1. If the most significant bit of the data is 0, then 0 is added; if the most significant bit is 1, then 1 is added.

comparison operators

Python supports comparison operators as shown in the following table:

Comparison operator Description> Greater than, returns True if the value preceding> is greater than the value following, otherwise returns False.= Returns True if the preceding value is greater than or equal to the following value; otherwise returns False.
