Dictionaries are mappings from key objects to value objects. 字典由键:值对组成,其中键必须是不可变的,值可以是任何值。 Dictionaries consists of Key:Value pairs, where the keys must be immutable and the values can be anything. 词典本身是可变的,因此这意味着一旦创建词典,就可以动态修改其内容。 Dict...
new_list = [(key,)+tuple(val) for dic in list for key,val in dic.items()] 1. Here we iterate over all dictonaries in list. For every dictionary we iterate over its .items() and extract the key and value and then we construct a tuple for that with (key,)+val. Whether the v...
keyspecifies a function of one argument that is used to extract a comparison key from each list element:key=str.lower. The default value isNone(compare the elements directly). reverseis a boolean value. If set toTrue, then the list elements are sorted as if each comparison were reversed. ...
