Python的操作顺序与正常的数学相同:先括号,然后为指数,然后是乘法/除法,然后是加法/减法。 The following table lists all of Python's operators, from highest precedence to lowest. 下表列出了所有Python的操作符,从最高优先到最低。 Operators in the same box have the same precedence. 同一框中的操作符具有相同的优先级。
1 Lambda #运算优先级最低 2 逻辑运算符: or 3 逻辑运算符: and 4 逻辑运算符:not 5 成员测试: in, not in 6 同一性测试: is, is not 7 比较: <,<=,>,>=,!=,== 8 按位或: | 9 按位异或: ^ 10 按位与: & 11 移位: << ,>> 12 加法与减法: + ,- 13 乘法、除法与取余: *...
If an expression has two operators with similar precedence, the expression is evaluated according to its associativity (either left to right, or right to left). For example, print(6 * 4 / 3) // 8 Here, operators * and / have the same precedence. And, their associativity is from left...
With some tweaks, we can use the+operator to work with user-defined objects as well. This feature in Python, which allows the same operator to have different meanings depending on the context is calledoperator overloading. Python Special Functions In Python, methods that have two underscores,_...

答案是否定的。 您可以使用+运算符添加一个类的两个对象吗?+运算符可以添加两个整数值,两个浮点值或仅可用于连接两个字符串,因为这些行为已在python中定义。 So if you want to use the same operator to add two objects of some user defined class then you will have to defined that behaviour yourself...
Take a quick interactive quiz on the concepts in Python: Operator of Precedence or print the worksheet to practice offline. These practice questions will help you master the material and retain the information.
4. How do parentheses affect operator precedence in Python? A. They have no effect B. They override default precedence C. They reduce runtime D. They only affect logical operators Show Answer 5. Which of the following operators has the same precedence as comparison operators? A. Logic...
As in traditional mathematics, multiplication is done first: letx =100+50*3; Try it Yourself » When using parentheses, operations inside the parentheses are computed first: letx = (100+50) *3; Try it Yourself » Operations with the same precedence (like * and /) are computed from ...
Let's understand the operator precedence via simple examples.ExampleIn the example below, the first expression contains the division, modulo, and multiplication operators with the same precedence. So, the compiler will use the associativity rule, which is left to right for multiplication, division, ...
