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
<
You can write
i = 5 + tup()[0]
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
my_tuple = (89, 32)
my_tuple_with_more_values = (1, 2, 3, 4, 5, 6)
# to concatenate tuples
another_tuple = my_tuple + my_tuple_with_more_values
print(another_tuple)
# (89, 32, 1, 2, 3, 4, 5, 6)
# getting a value from a tuple is similar to a list
first_val = my_tuple[0]
second_val = my_tuple[1]
# if you have a function called my_tuple_fun that returns a tuple,
# you might want to do this
my_tuple_fun()[0]
my_tuple_fun()[1]
# or this
v1, v2 = my_tuple_fun()
Hope this clears things up further for those that need it.
