for num in data:# Use the ternary operator to determine if the number is even or odd result = 'even' if num % 2 == 0 else 'odd'# Optionally, print the result of the ternary operator for each element print(f'The number {num} is {result}.')输出 The number 3 is odd.The number...

In the case of Loops, it was used for iteration, whereas in this case it’s a conditional that can be eithertrueorfalse.It’ll be true if the substring is part of the string, and false if it’s not. 3. Transforming Strings There are a bunch of fun methods for transforming our stri...
布尔表达式(boolean expression)是指一个表达式真或假(true or false)。下列例子用运算符==比较两个运算对象并得出True或False:True和False是特殊值,属于bool类型,而非字符串:==是关系运算符(relationaloperators)之一,其他如:注意:=是赋值运算符,而==是关系运算符(等于);无=<或=>。4.3 逻辑运算...
以我现在的视角分析,其实就是开发者们不满足于“if-else”的现状,但是当时流行的“and-or”写法并不够好,因此,大家期望 Python 设计出新的规范性语法,来解决这个痛点。 与众不同的条件表达式 在经过 10 天的邮件讨论后,Guido van Rossum 最终决定添加一个条件表达式,语法形式为X if C else Y。因此,PEP-308...
('More') Python 同样支持 ternary conditional operator: a if condition else b 也可以使用 Tuple 来实现类似的效果:test 需要返回 True 或者 False (falseValue, trueValue)[test] 更安全的做法是进行强制判断 (falseValue, trueValue)[test == True] 或者使用 bool 类型转换函数 (falseValue, trueValue)[...
