anacondas prompt.cd command to use folder and then python vlookup.py.
but no output.I am new to .py,help me

import pandas as pd

def vlooup(input_file, common_column, lookup_columns):
    # Read input file
    input_df = pd.read_csv(input_file)
    
    # Ask for file paths to lookup
    file_paths = {}
    for column in lookup_columns:
        file_paths[column] = input(f"Enter the file path for column '{column}': ")
    
    # Perform lookup
    result = {}
    for index, row in input_df.iterrows():
        common_value = row[common_column]
        result[common_value] = {}
        for column, file_path in file_paths.items():
            lookup_df = pd.read_csv(file_path)
            if common_value in lookup_df[common_column].values:
                result[common_value][column] = lookup_df.loc[lookup_df[common_column] == common_value]
            else:
                result[common_value][column] = f"No matching value found in {column}"
    
    return result

if __name__ == "__main__":
    input_file = input("Enter the path to the input file: ")
    common_column = input("Enter the name of the common column: ")
    lookup_columns = input("Enter the names of the columns to lookup (separated by comma): ").split(',')
    
    result = lookup_files(input_file, common_column, lookup_columns)
    print(result)

run the python vlooup.py
