插入元素: 插入元素: 在列表指定位置idx添加元素aList.insert(idx, a)(原先idx位置的元素及其后面的元素会自动后移) ; 删除元素: 删除元素: 删除LIst中的某一项,函数List.remove(), 括号中填写要删除的内容 List各元素中插入元素: List各元素中插入元素:“string”.join(List) example: 查索引(.index .index...
List=['1','2','3'] print(List) for x in List: print(x) 1. 2. 3. 4. 输出结果: 1 2 3 1.深入研究循环 循环是一种重要的概念,它是计算机自动完成重复工作的常见方式。如前面的例子,Python首先读取到 for x in List: 1. 对于循环中的每个元素,都会执行for循环中的语句。另外,在编写for循环...

list1=['a','b','c']for i,item in enumerate(list1): print(f"{i}:{item}")输出：:a1:b2:c 输出两个 Python 列表 若要将两个列表一起输出，可以使用for循环和zip()函数。zip()函数返回一个迭代器，该迭代器是一个元组，循环遍历并输出列表元素。list1=['a','b','c']list2=['a2','...

一般的，简单的for循环可以打印出list的内容：l=[1,2,3,4]for i in l:print(i)若想得到以空格或逗号为分隔符的输出结果，代码可改为：l=[1,2,3,4]for i in l:print(i,end=' ')#以空格为分隔符 输出结果为：1 2 3 4 （注意，此时4后面还有一个空格）。l=[1,2,3,4]for i ...
