my_dict = {k:v for k, v in sorted_freq} # sorted_freq is a list containing key:value.
{'like': 4870,
'taste': 4508,
'good': 3569,
'flavor': 3449,
'one': 3217,
'product': 3197,
'use': 3165,
'love': 3141,
'great': 3056,
'eat': 1614...}
对于字典中的所有键,如何用从1开始的自然数替换此字典中的键?
[('like', 4870),
('tast', 4508),
('good', 3569),
('flavor', 3449),
('one', 3217),
('product', 3197),
('use', 3165),
('love', 3141),
('great', 3056),
'get', 2400)...]
答案 0 :(得分:2)
如果从字典开始:
您可以尝试在字典理解中使用enumerate
,但要注意,字典不适合depending on the version of python进行排序:
{i:v for i,(k,v) in enumerate(my_dict.items(), 1)}
{1: 4870, 2: 4508, 3: 3569, 4: 3449, 5: 3217, 6: 3197, 7: 3165, 8: 3141, 9: 3056, 10: 1614}
如果从元组列表开始(如您刚在编辑中发布的那样):
sorted_freq = [('like', 4870),
('tast', 4508),
('good', 3569),
('flavor', 3449),
('one', 3217),
('product', 3197),
('use', 3165),
('love', 3141),
('great', 3056),
('get', 2400)]
{i:v for i,(k,v) in enumerate(sorted_freq, 1)}
