Python中的三目运算其实就是if...else...的语法糖 # 三目运算符:用于简化 if...else...的语法结构 # -- 1) 只能解决if...else...结构,其他if分支结构都不管 # -- 2)一个分支提供一个结果: 如果一个分支提供了多个结果, 将多个结果通过元组返回 a = int(input('a:'))b= int(input('b:'))...
max_value = x if x > y else (y if y > z else z) print(max_value) ``` 在这个例子中,我们定义了三个变量x、y和z,并使用Ternary参数来比较它们的大小。如果x大于y,则返回x的值。否则,我们使用另一个Ternary参数来比较y和z的大小。如果y大于z,则返回y的值,否则返回z的值。在这个例子中,z的值...
a:b| a if a>b else b JAVA: importstaticjava.lang.System.out;publicclassTernary {publicstaticvoidmain(String[] args) {inta = 4, b = 5; out.println(++a == b-- ? a : b);//5} } Python: a = 4b= 5print(aifa > belseb)...
Thus, using this conditional operator, users can simplytest a condition in a single line that replaces the multiline if-else, which increases the code readability. In other terms, the ternary operator defines using the conditional operator on three operands or variables. Syntax: [val_true]if[c...
Python程序由语句组成,大多数语句的大部分内容都是表达式。表达式仅包含其他表达式。 y += 1是一个语句,在期望表达式的地方不允许使用。整个三元条件表达式是一个表达式,它的每个部分都是表达式。没有理由允许(x += 1) if random.choice([0, 1]) else (y += 1),就像没有理由允许以下任何一个怪物一样: ...
Python’s ternary operator allows you to execute a statement based on whether a condition is true or false. This operator is essentially the same as anif-else statement, but can be kept to a single line and be more readable. A ternary operator or conditional expression will work best when...
int source = 1; int target = source ==1 ? 1 : 2; 在python中,也有类似的实现,主要有以下几种形式: 从2.4开始,Ternary操作通常是作为条件表达式出现的。 is_nice=Truestate="nice"ifis_niceelse"not nice" 还有一种更加晦涩因此并不常用的方法,该方法涉及tuples: ...
The ternary operator in C# is a shorthand notation for an if-else statement that takes three operands, hence its name "ternary". It is commonly used to evaluate a condition and assign a value based on whether the condition is true or false. The syntax of the ternary operator is as ...
The ifelse() function: a <- c(10,20,30) x <- ifelse(a== 10, 10,20 ) x [1] 10 20 20 x <- ifelse(a==20, 10, 20) x [1] 20 10 20 Defining operators: You can also define c style ?: ternary operator as follows: `?` <- function(x, y) eval( sapply( strsplit( ...
I was trying to use a ternary to print out a string if something was true and something else if it wasn't (simple enough, right?). It gives no errors and doesn't seem like it would cause any trouble. However, when running... print('[',dr+1,']\t',d[dr] if fullpath else '...
