当不确定优先级时,可以使用圆括号来明确运算的顺序。 - Python 官方文档提供了一个完整的运算符优先级表Operator precedence,你可以自己查阅,帮助你更好地理解和记忆这些优先级。 下面是一些使用这些运算符的代码示例,以帮助你理解优先级是如何影响代码求值的。 # 优先级示例代码# 括号改变运算顺序result=(2+3)*4p...
Python Operator Precedence - An expression may have multiple operators to be evaluated. The operator precedence defines the order in which operators are evaluated. In other words, the order of operator evaluation is determined by the operator precedence.
Operator Precedence#运算优先级 Operator precedence is a very important concept in programming. It is an extension of the mathematical idea of order of operations (multiplication being performed before addition, etc.) to include other operators, such as those in Boolean logic. The below code shows...
