# For Python

# 6.17 # In the "Strings: A Deeper Look" chapter's exercises (chapter 8), you'll write a script that enables its users to enter ingredients from a cooking recipe, then recommends healthier replacements. # In preparation for that exercise, create a dictionary that maps ingredients to lists of potential replacements. # Some ingredient replacements are shown below:

# Ingredient: # Substitution: # 1 cup sour cream # 1 cup yogurt # 1 cup milk # 1/2 cup evaporated milk and 1/2 cup water # 1 teaspoon lemon juice # 1/2 teaspoon vinegar # 1 cup sugar # 1/2 cup honey, 1 cup molasses, or 1/4 cup agave nectar # 1 cup butter # 1 cup margarine or yogurt # 1 cup flour # 1 cup rye or rice flour # 1 cup mayonnaise # 1 cup cottage cheese or 1/8 cup mayonnaise and 7/8 cup yogurt # 1 egg # 2 tablespoons cornstarch, arrowroot flour, or potato starch or 2 egg whites or 1/2 of a large banana (mashed) # 1 cup of milk # 1 cup soy milk # 1 cup oil # 1 cup applesauce

# Your dictionary should take into consideration that replacements are not always one-for one. # For Example, if a cake recipe calls for three eggs. it might reasonably use six egg whites instead. # Research conversion data for measurements and ingredient substitutes online. # Your dictionary should map the ingredients to lists of potential substitutes.
