No clue why Tuples in Python are immutable.   It seems to me that this is a flaw in the language.   I’m no expert on underlying programming language architecture.    But it seems to me that if I want a

myTuple = {('NAMED1':variable1,
            'NAMED2':variable2,
            'NAMED3':variable3)}

Where there is some interrelation between variable1, variable2 and variable3. If I subsequently what to set NAMED3 to new variable4. There is no way to do this.

Wouldn’t it be nice if one could do?

  
myTuple['NAMED3'] = variable4 

So now I’d have:

myTuple = {('NAMED1':variable1,
            'NAMED2':variable2,
            'NAMED3':variable4)}

This fails because of Tuples immutability.

One way to overcome this is create a new Tuple and then delete the existing Tuple.    This becomes very interesting when I have  list of Tuples were you make a new tuple add it to the list and delete the existing Tuple.

Seems like a lot of hassle for a language which is suppose to be very programmer friendly.
