How Do You Replace Variables With Their Values?

[Aldwin Pollefeyt]

Wow, I'm so sorry I answered on the question : "How do you replace a
variable with its value". For what i understood with the example values,
CrazyVideoGamez wants 3 variables named like the meal-names in dictionary.
Yes, it's not secure unless you work with your own dataset (just like
sending your own created commands with set=True in subprocess). Yes there
might be better solutions for the real problem. But maybe the user really
has a purpose for it, in a secure environment with own datatset, it's a
valid answer for "How do you replace a variable with its value".
