在一個列表中添加復數，在另一個列表中添加單個

Question

我正在制作一份包含復數和單數的列表。 我想創建兩個單獨的列表：一個列表用於復數，一個列表用於單個列表。

my_list = ['Accounts', 'Account', 'Accredited Investor', 'Accredited Investors', 'Issuer']
plurals = []
singulars = []
for a, b in itertools.combinations(my_list, 2):
    dist = levenshtein_distance(a, b)
    if dist == 1:
        if a[-1:] == 's':
            letter_with_s = a
            plurals.append(a)
        if b[-1:] == 's':
            letter_with_s = b
            plurals.append(a)
        else:
            pass
    else:
        print('False')

我想要的是： plurals = ['Accounts', 'Accredited Investors']

我得到的是： plurals = ['Accredited Investor', 'Accredited Investor']

Answer 1

這僅適用於's'案例：

my_list = ['Accounts', 'Account', 'Accredited Investor', 'Accredited Investors', 'Issuer']
words = set(my_list)
plurals = [i for i in my_list if i[:-1] in words]
singulars = [i for i in my_list if i+'s' in words]
