One-Line If/Else Statements (Ternary Operator) In Python, you can use a concise syntax for simpleif/elsestatements. This is known as the Ternary Operator. It’s a one-liner conditional expression that evaluates to a value based on a condition. Example: num=int(input("Enter a number: ")...
In the above case Python evaluates each expression (i.e. the condition) one by one and if a true condition is found the statement(s) block under that expression will be executed. If no true condition is found the statement(s) block under else will be executed. In the following example,...
1 class str(basestring): 2 """ 3 str(object='') -> string 4 5 Return a nice string representation of the object. 6 If the argument is a string, the return value is the same object. 7 """ 8 def capitalize(self): 9 """ 首字母变大写 """ 10 """ 11 S.capitalize() -> str...

In Python, there’s a way to write a “quick” or “short-hand” if else statement, comprising of just one line. Good for readability and conserving number of lines. Known as the “short hand” if else statement. if a > b: print("a greater than b") ...
1、python的分支结构主要包含三大类: (1)单分支结构if语句 (2)二分支结构if-else语句 (3)多分支结构 2、python里面所有非零的数值或者其他非空的是数据类型都等效为True,而只有数值0等效为False,所以在判断语句里面需要注意输出的成立与不成立。 3、python里面的循环语句分为遍历循环和无限循环 ...
python if else单行 a = [1,2,3] b = a if len(a) != 0 else "" b = [1,2,3]#结果 a = [] b = a if len(a) ! 1.3K20 Rust基础语法(条件控制语句if、loop、while、for) Rust 有三种循环:loop、while 和 for。可以使用 break 关键字来告诉程序何时停止循环。...循环中的 continue 关...

可以有零个或多个 elif 部分,以及一个可选的 else 部分。 关键字 ‘elif’ 是‘else if’ 的缩写,适合用于避免过多的缩进。 一个 if … elif … elif … 序列可以看作是其他语言中的 switch 或 case 语句的替代。 4.2. for 语句 Python 中的 for 语句与你在 C 或 Pascal 中所用到的有所不同。
注意: else与while搭配, 这是python的特点, 如果循环从break终止, 跳出循环, 正常结束就执行else, 当你不行继续, 输入no, 也是会有 goodbye! else 也可以与for 搭配, 用法与while一样. 问题: 下面代码输出什么? foriinrange(1, 10, 2):ifi % 5 ==0:print("Bingo!")breakelse:print(i) ...
