不能用replace方法,replace方法只能用在dataframe上 series.replace(to_replace='None', value=np.nan, inplace=True, regex=False) # 下面两种都是对的,要注意不能串 df_X = df_X.replace([np.inf, -np.inf], np.nan).copy() df_X.replace([np.inf, -np.inf], np.nan, inplace=True) ...
Exampleto convert pandas DataFrame to dict In the below example, we read the input from theStudentData.csvfile and create a DataFrame object. It is then converted into the Python dictionary object. Input CSV file contains a simple dataset of student data with two columns, “Name” and “Mark...
In this output, each column name from the DataFrame becomes a key in the JSON file. The values under each key form another dictionary where the keys are the indices from the DataFrame and the values are the corresponding cell values.
