I'm doing a Recipe program project for GCSE Computing. It stores recipes in .txt documents and then when requested it will open and present the information for those to read. At this moment in time, it stores the recipe at the top of the .txt file and the ingredients at the bottom. It runs thorugh heading1 for the recipe and splits it up for presenting. Then it should go through heading2 and look through each column, ingredients, weight and measurement. Then using a for loop, will go through the lists and present the ingredients together with their respective weight and measurement. Code is as below:
