list_name.index(item) It will print the index value of an item from the list_name.Example 1:# list list = ["Gwalior", "Bhopal", "Indore", "Noida", "Delhi", "Ajmer"] # Now, using the index() to get the index # of "Inodre" Index_Value = list.index("Indore") # Printing...
print(nested_dict['user2']['age']) # 输出: 4.52.2.2get()方法安全访问 当不确定某个键是否存在时,使用get()方法代替直接索引可避免引发KeyError异常。get()方法接受两个参数:要查找的键和一个可选的默认值,若键不存在则返回默认值。 print(nested_dict.get('user3', {}).get('name', 'Unknown'))...
其基本结构如下：new_list = [expression for item in iterable if condition]这里，expression 是对item进行操作或变换的表达式，iterable 是你要遍历的可迭代对象（如列表、字符串、range等），if condition 是可选的筛选条件。列表推导式就像一台高效的“数据加工厂” ，它从原料（iterable）中提取原料粒子（item）...
