将“记录”参数传递给Pandas to_dict方法 [英] Passing 'records' parameter to Pandas to_dict method
本文介绍了将“记录”参数传递给Pandas to_dict方法的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
import numpy as np
import pandas as pd
data = np.random。 randn(5,5)
df = pd.DataFrame(data)
dict1 = df.to_dict(outtype ='records')
这是我得到的错误:
值错误:outtype记录不明白
但是,当我查看文档对于该方法,记录被列为有效参数。此外,我可以将我的数据框转换为docs(list,series和dict)中提到的所有其他字典格式。我不知道会发生什么问题。
解决方案
尝试这样:
dict1 = df.to_dict('records')
I have a dataframe that I'd like to convert to a dictionary. I want each column in the dataframe to be mapped to the values in it.
import numpy as np
import pandas as pd
data = np.random.randn(5,5)
df = pd.DataFrame(data)
dict1 = df.to_dict(outtype = 'records')
Here is the error I get:
Value Error: outtype records not understood
However, when I check the docs for this method, records is listed as a valid parameter. Moreover, I am able to convert my dataframe to all the other dictionary formats mentioned in docs (list, series, and dict). I'm not sure what could be going wrong.
解决方案
Try this:
dict1 = df.to_dict('records')
