Hello!
I need to store more data, and in order to do so, I would need multi-dimensional version of a dictionary... For example, let m be an object such that if you give the name and the age, such as m [Cathy, 19], then it returns the phone number. (In a dictionary you have one variable, and now I must call the data by more variables...) Do you know such a command?
If I correctly understand your question, dictionaries can do this. You just need to use tuples as keys. Example:
sage: m = {} # an empty dictionary
sage: m[('Cathy', 19)] = '555-1212'
sage: m[('Cathy', 19)]
'555-1212'
You're welcome! In fact, lists won't work as keys. Look up 'mutable' vs. 'immutable' in connection with Python to understand why.
You can also construct the tuples "implicitly" by doing m['Cathy', 19] = '555-1212' .
