While working with complex problems in Python, we need to create new collections that are a combination of elements of the given collection and have different properties that perform different functions as per the programmer's requirement. Here, we will be creating a tuple from string and list i...
指定位置插入 infos_list.insert(0,"Python") 插入列表 infos_list.insert(0,temp_list) Python在指定位置插入列表是真的插入一个列表进去,C#是把里面的元素挨个插入进去 看后面的列表嵌套,是通过下标方式获取,eg: infos_list[0][1]In [5]: # 添加～指定位置插入 infos_list.insert(0,"Python") print(...
列表(list):有序、可变,用[]表示,支持增删改查 元组(tuple):有序、不可变,用()表示 集合(set):无序、唯一,用{}表示,支持交集、并集等操作 字典(dict):键值对结构,用{key: value}表示,键必须唯一且不可变 2. 运算符与表达式 算术运算符:+、-、*、/、//(整除)、%(取余)、**(幂运算) ...

x = a[1:4] print(x) print(type(x)) 1. 2. 3. 4. 5. 6. 执行和输出: 3. 列表长度 其实本文第 1. 节中已经用到了,将列表作为参数调用 Python 的全局函数就可以得到列表长度。 查找列表长度的 len() 函数语法如下: len(listname)
