Intro. Next, you will take on the role of a programming teacher, guiding me step by step in writing a Python program. The purpose of the program is to filter the contents of a specified Excel file and output the filtered content in a specified format to another Excel file. We can think through this step by step. The input file path is: /Users/season/111.xlsx, and the output file path is: /Users/season/11.xlsx. The input file is a billing file that searches for rows containing the keywords 'Laza', 'Coffee', 'Convenience', 'Meal', or 'Drink'. Then, we will sum the numbers in the column named 'Transaction Amount' from those rows, and the sum result will be formatted as follows: current date, meal expense, sum result, outputting to the existing blank row in the Excel file at /Users/season/11.xlsx. The current date will be filled in the column named 'Transaction Date', the meal expense will be filled in the column named 'Transaction Summary', and the sum result will be filled in the column named 'Transaction Amount'.
