Is there a way to get one value from a tuple in python using expressions?
def Tup(): return (3,"hello") i = 5 + Tup(); ## I want to add just the three
I know I can do this:
(j,_) = Tup() i = 5 + j
But that would add a few dozen lines to my function, doubling its length.
You can write
i = 5 + Tup()
Tuples can be indexed just like lists.
The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.
For anyone in the future looking for an answer, I would like to give a much clearer answer to the question.
# for making a tuple MyTuple = (89,32) MyTupleWithMoreValues = (1,2,3,4,5,6) # to concatinate tuples AnotherTuple = MyTuple + MyTupleWithMoreValues print AnotherTuple # it should print 89,32,1,2,3,4,5,6 # getting a value from a tuple is similar to a list firstVal = MyTuple secondVal = MyTuple # if you have a function called MyTupleFun that returns a tuple, # you might want to do this MyTupleFun() MyTupleFun() # or this v1,v2 = MyTupleFun()
Hope this clears things up further for somebody.
