如何从字典中删除重复值? [英] How to remove duplicate values from dict?

问题描述

我正在尝试删除字典中的重复值，但是它不起作用:

I'm trying to remove duplicate values in my dict but its not working:

samples_antibiotics_with_duplicates = {'S00541-09': ['Streptomycin', 'Sulfamethoxazole', 'Trimethoprim', 'Spectinomycin', 'Streptomycin', 'Streptomycin', 'Trimethoprim']}
samples_antibiotics = {}
    for key,value in samples_antibiotics_with_duplicates.iteritems():
      if value not in samples_antibiotics.values():
        samples_antibiotics[key] = value
print samples_antibiotics

此打印:

{'S00541-09': ['Streptomycin', 'Sulfamethoxazole', 'Trimethoprim', 'Spectinomycin', 'Streptomycin', 'Streptomycin', 'Trimethoprim']}

推荐答案

您可以尝试以下操作:

samples_antibiotics_with_duplicates = {'S00541-09': ['Streptomycin', 'Sulfamethoxazole', 'Trimethoprim', 'Spectinomycin', 'Streptomycin', 'Streptomycin', 'Trimethoprim']}

new_dict = {a:list(set(b)) for a, b in samples_antibiotics_with_duplicatates.items()}
