Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...

List(列表) Tuple(元组) Set(集合) Dictionary(字典) 变量赋值 Python 并不需要声明变量的类型,所说的"类型"是变量所指的内存中对象的类型。但每个变量使用前都必须赋值,然后才会创建变量。给变量赋值的方法是采用等号(=),等号左边是变量名,右边是存储在变量中的值。
Here, the list is sorted based on theage(i.e., second element) of each tuple. Sort Example With Both Parameters We can use bothkeyandreverseparameters for sorting the list. For example, words = ['python','is','awesome','and','fun'] ...
