随机赋值

Question

我正在开发一个程序，该程序应该将女性舞伴分配给男性舞伴。用户选择一个男舞者，程序应该随机分配一个女舞者，然后从原始列表中删除两个选择的舞者。在我的编码课上，我从来没有被教过如何像这样随机分配。这是我到目前为止的代码：

import random


maledancers = {"Maciek", "Marek", "Marcel", "Carson", "Brett", "Connor"}
femaledancers = {"Renata", "Karolina", "Maja", "Natalia", "Olivia", "Meghan"}



print("You will be pairing the male dancers with the female dancers.")
print("You will select one of the male dancers and it will get paired with a female dancer randomly")

dancer = input("Out of the male dancers, please select one to be paired: ")

if dancer not in maledancers:
    print("Your choice is not in the list of dancers, please re-enter a dancer from the list")
if dancer in maledancers:
    print("Great we will now randomly give " + dancer + " a partner to dance with")
if dancer.isdigit():
    print("The dancer can't have any numbers in their name. Try again please!")

如果有人对我可以在这里做什么有任何意见，我非常感谢任何帮助。如果您回答此问题，请显示代码更改。提前致谢！

Answer 1

应该这样做：

import random


maledancers = {"Maciek", "Marek", "Marcel", "Carson", "Brett", "Connor"}
femaledancers = {"Renata", "Karolina", "Maja", "Natalia", "Olivia", "Meghan"}


print("You will be pairing the male dancers with the female dancers.")
print(
    "You will select one of the male dancers and it will get paired with a female dancer randomly"
)

for i in range(len(maledancers)):

    dancer = input("Out of the male dancers, please select one to be paired: ")

    if dancer not in maledancers:
        print(
            "Your choice is not in the list of dancers, please re-enter a dancer from the list"
        )

    if dancer in maledancers:
        print("Great we will now randomly give " + dancer + " a partner to dance with")

        # get a random female
        random_female = random.choice(list(femaledancers))
        # remove that female and male
        femaledancers.remove(random_female)
        maledancers.remove(dancer)

        # do wtevr u want with this female now

我建议使用列表而不是集合，以避免在选择随机女性时频繁转换为列表。

也不知道为什么你有最后一个 if 语句，关于 isdigit。
