Packing a tuple: fruits = ("apple","banana","cherry") Try it Yourself » But, in Python, we are also allowed to extract the values back into variables. This is called "unpacking": Example Unpacking a tuple: fruits = ("apple","banana","cherry") ...
Unpacking a tuple in Python is the process by which you can extract the contents of a tuple into separate variables. There are two ways to unpack a tuple: 1. Using the assignment operator. 2. Using the destructuring (*) operator.
# You can do most of the list operations on tuples too len(tup) # => 3 tup + (4, 5, 6) # => (1, 2, 3, 4, 5, 6) tup[:2] # => (1, 2) 2 in tup # => True 我们可以用多个变量来解压一个tuple: # You can unpack tuples (or lists) into variables a, b, c = (...
We already know that we can unpack each of the things in each of these key-value tuples into two variables (say thing and count):>>> for item in things.items(): ... thing, count = item ... print(thing, count) ... ducks 2 lamps 3 chairs 0 ...
, we have a tuplemy_tuplewith five elements, but we’re trying to unpack three values intofirst,secondandthird. This will result in the “too many values to unpack” error because there is a mismatch between the number of elements in the tuple and the number of variables to unpack....
