A dictionary maps a key to exactly one value. If you want multiples,
you do pretty much what you've done here...

... but instead of using parentheses and creating a Tuple, use square
brackets and create a List:

mydict = {'Name':['Name1','Name2','Name3'],'Tel':['023333','037777','049999']}

Then you can append to it, and it will work just fine!
