Depending on the content's name, converting a text file into a list of dictionaries or a list
Question:
I have a question, I’m not sure where to begin. I have a text file with all the contents of recipes and other things. I wonder if there’s a straightforward way to replace the text file and make it into the example of the function that I’ve pasted at the bottom. If not, does that imply that in order to turn some texts into lists and dictionaries by iterating through each line and splitting at certain places?

To make a list of dictionaries from the text you can do (text variable contains string from your question):
out, current = [], None
for line in text.splitlines():
if line.startswith("name:"):
if current:
out.append(current)
current = {"name": line.split(":", maxsplit=1)[1]}
elif ":" in line:
k, v = line.split(":", maxsplit=1)
if k == "categories":
v = v.split(";")
current.setdefault(k, []).extend(v)
else:
current.setdefault(k, []).append(v)
if current:
out.append(current)
print(out)
