Pandas adding extra zeros to decimal value

Question

I'm importing a file into pandas dataframe but the dataframe is not retaining original values as is, instead its adding extra zero to some float columns.

example original value in the file is 23.84 but when i import it into the dataframe it has a value of 23.8400

How to fix this? or is there a way to import original values to the dataframe as is in the text file.

For anyone who encounters the same problem, I'm adding the solution I found to this problem. Pandas read_csv has an attribute as dtype where we can tell pandas to read all columns as a string so this will read the data as is and not interpret based on its own logic.

df1 = pd.read_csv('file_location', sep = ',', dtype = {'col1': 'str', 'col2': 'str'}

I had too many columns so I first created a dictionary with all the columns as keys and 'str' as their values and passed this dictionary to the dtype argument.
