我有一个问题,如何计算相同键的总字数?我有一个字典:
{'learning': {'DOC1': 0.14054651081081646,
'DOC2': 0,
'DOC3': 0.4684883693693881},
'life': {'DOC1': 0.14054651081081646,
'DOC2': 0.20078072972973776,
'DOC3': 0}
}
我希望结果为:
{'learning life': {
'DOC1': DOC1 in learning + DOC1 in life,
'DOC2': DOC2 in learning + DOC2 in life,
'DOC3': DOC3 in learning + DOC3 in life,}}
非常感谢

非常简单:
for k in d['learning']:
print(d['learning'][k] + d['life'][k])
... d
是您的dict
并且没有任何错误检查(密钥是否存在,是否真的是数字等)。
d = {'learning': {'DOC1': 0.14054651081081646,
'DOC2': 0,
'DOC3': 0.4684883693693881},
'life': {'DOC1': 0.14054651081081646,
'DOC2': 0.20078072972973776,
'DOC3': 0}
}
d['sum'] = [d['learning'][k] + d['life'][k]
for k in d['learning']]
print(d)

您可以使用字典理解来添加嵌套在字典d
中的所有数字,如下所示:
totals = {k: sum(v.get(k, 0) for v in d.values()) for k in d.values()[0]} # dict of totals
