将'records'参数传递给Pandas to_dict方法

Question

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.

Answer 1

尝试这个：

dict1 = df.to_dict('records')
