Python如何从具有多个值的字典键中删除特定值？

问题描述

我有一个字典，每个键有多个值，每个值都有两个元素（可能更多）。我想遍历每个键的每个值对，并删除那些符合某些条件的值对。例如，在这里我想删除键A的第二个值对。即：（'Ok！'，'0'）：

I have a dictionary with multiple values per key and each value has two elements (possibly more). I would like to iterate over each value-pair for each key and delete those values-pairs that meet some criteria. Here for instance I would like to delete the second value pair for the key A; that is: ('Ok!', '0'):

myDict = {'A': [('Yes!', '8'), ('Ok!', '0')], 'B': [('No!', '2')]}

至：

myDict = {'A': [('Yes!', '8')], 'B': [('No!', '2')]}

我可以通过键或值来遍历字典，但无法弄清楚如何删除特定值。

I can iterate over the dictionary by key or value, but can't figure out how I delete a specific value.

推荐答案

像这样的代码：

myDict = {'A': [('Yes!', '8'), ('Ok!', '0')], 'B': [('No!', '2')]}
for v in myDict.values():
    if ('Ok!', '0') in v:
        v.remove(('Ok!', '0'))
print(myDict)
