Question

我想我遇到了一个初学者的问题： ->我想遍历一个数组，然后将值插入执行的代码行中。对于下面的尝试，我得到“ SyntaxError：无法分配给运算符”

#Country-subsets (all countries in dataframe)
for s in country_filter:  
  s.lower() + '_immu_edu' = immu_edu.loc[immu_edu['CountryName'] == s]

感谢您的帮助！

我的预期输出是：

guinea_immu_edu = immu_edu.loc[immu_edu['CountryName'] == "Guinea"]
lao_immu_edu = immu_edu.loc[immu_edu['CountryName'] == "Lao PDR"]
bf_immu_edu = immu_edu.loc[immu_edu['CountryName'] == "Burkina Faso"]
us_immu_edu = immu_edu.loc[immu_edu['CountryName'] == "United States"]
ge_immu_edu = immu_edu.loc[immu_edu['CountryName'] == "Germany"]

Answer 1

将值存储在字典中，并使用以下键进行访问：

my_dict = dict()
for s in country_filter:  
  my_dict[s.lower() + '_immu_edu'] = immu_edu.loc[immu_edu['CountryName'] == s]

Python-For循环-运行输出的每一行
