Python中的join()函数用于将字符串列表连接成一个字符串。它接受一个可迭代对象作为参数,并返回一个由可迭代对象中的字符串元素连接而成的字符串。 在使用join()函数时,我们可以使用if-else语句创建一个条件表达式的oneliner,以根据特定条件选择要连接的字符串列表。这种写法可以简化代码并提高可读性。
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: ")...

(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 (1)遍历循环结构:for n in x (2)无无限循环:while(条件) 4、break和cont...
