Let’s start with LoanDurationDays. Since we are filling missing values with the number of days between LoanStartDate and LoanEndDate, it’s important that we first ensure that the dates are in correct format.
This code snippet cleans and standardizes date data in a DataFrame, specifically in the 'LoanStartDate' column. It defines a function, parse_dates, to convert dates into a consistent format, handling two common formats and marking unparseable dates as missing (pd.NaT). This function is applied to the 'LoanStartDate' column of loan_data_cleaned.
