python 唯一元素

Here, we are implementing a python program to check whether all elements of a list are unique or not?

在這里，我們正在實現一個python程序來檢查列表的所有元素是否唯一？

It's very simple to check, by following two steps

按照以下兩個步驟進行檢查非常簡單

Convert the list in a set (as you should know that set contains the unique elements) – it will remove the duplicate elements if any.

轉換列表中的列表(您應該知道該集合包含唯一元素)–它將刪除重復的元素(如果有)。

Then, compare the length of the list and set – if both are the same then all elements are unique.

然后，比較列表和集合的長度–如果兩者相同，則所有元素都是唯一的。

Program:

程序：

# function to check unique def check_unique(x):return len(x) == len(set(x))# lists x = [10, 20, 30, 40,50] y = [10, 20, 20, 20, 20] z = [10, 10, 10, 10, 10]print("x: ", x) print("len(x): ", len(x)) print("set(x): ", set(x)) print("len(set(x)): ", len(set(x))) print("check_unique(x): ", check_unique(x)) print()print("y: ", y) print("len(y): ", len(y)) print("set(y): ", set(y)) print("len(set(y)): ", len(set(y))) print("check_unique(y): ", check_unique(y)) print()print("z: ", z) print("len(z): ", len(z)) print("set(z): ", set(z)) print("len(set(z)): ", len(set(z))) print("check_unique(z): ", check_unique(z)) print()

Output
