防止pandas.read_csv推断dtypes

Question

How to prevent pandas.read_csv() from inferring the data types. For example, its converting strings true and false to Bool: True and False . The columns are many for many files, therefore not feasible to do:

df['field_name'] = df['field_name'].astype(np.float64) for each of the columns in each file. I prefer pandas to just read file as it is, no type inferring.

Answer 1

对于Pandas，请使用参数dtype=object在加载时保持数据。
