根据元组中的字典值删除元组列表中的元组

Question

我有一长串包含字典的元组。我想删除“权重”值为 1 的元组。List_example = [('WHT', 'WML, {'weight': 48}), ('WHHT','CCH', {'weight': 53}), ('WRT','KUF', {'weight': 1}), ('WHHT','RWH',{'weight': 1}))]期望的输出：List_example = [('WHT', 'WML, {'weight': 48}), ('WHHT','CCH', {'weight': 53}))]

Answer 1

以下

lst = [('WHT', 'WML', {'weight': 48}),

 ('WHHT','CCH', {'weight': 53}),

 ('WRT','KUF', {'weight': 1}),

 ('WHHT','RWH',{'weight': 1})]

 

new_lst = [x for x in lst if x[2]['weight'] != 1]

print(new_lst)

输出

[('WHT', 'WML', {'weight': 48}), ('WHHT', 'CCH', {'weight': 53})]
