Prevent pandas.read_csv from inferring dtypes
Use the parameter dtype=object for Pandas to keep the data as such at load time.
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.
