在这个判断重复值的情况下,设计一个简单的类来封装逻辑也是一个好主意。 ListChecker+list my_list+set unique_values+check_duplicates() : void+add_value(value) : void 这个类ListChecker负责检查一个列表中的重复值,实现一个check_duplicates方法来执行这一检查,并定义一个add_value方法用于添加值到集合中。
Check if an element exists in a list in Python by leveraging various efficient methods, each suited to different scenarios and requirements.

In this code block, we first define a listmy_listcontaining three strings: “apple”, “banana”, and “cherry”. Then, we use theinoperator to check if “banana” is present inmy_list. If it is, the code inside theifstatement is executed, printing “Found!” to the console. 2. U...
