type conversion in python from float to int

Question

I am trying to change data_df which is type float64 to int.

data_df['grade'] = data_df['grade'].astype(int)

I get the following error.

invalid literal for int() with base 10: '17.44'

Answer 1

From:

data_df['grade'] = data_df['grade'].astype(int)

Need to change int into 'int'

data_df['grade'] = data_df['grade'].astype('int')
