In Python, Tuple unpacking is a feature that allows us to assign values to multiple variables in a single statement. It works by unpacking a sequence (e.g., atuple,list, orstring) into individual variables. Unpacking is not limited to lists, you can also use it tounpack tuples, strings...
Note: The number of variables must match the number of values in the tuple, if not, you must use an asterisk to collect the remaining values as a list.Using Asterisk*If the number of variables is less than the number of values, you can add an * to the variable name and the values ...
If the number of variables is more or less than the length of tuple, Python raises a ValueError.ExampleOpen Compiler tup1 = (10,20,30) x, y = tup1 x, y, p, q = tup1 It will produce the following output −x, y = tup1 ^^^ ValueError: too many values to unpack (expected ...

tuples = ('Spark', 'Python', 'pandas', 'Java') # convert tuple into list list1 = [*tuples,] print(list1) # Output # ['Spark', 'Python', 'pandas', 'Java'] 3. Unpacking Tuple as Arguments You can unpack tuple and pass the elements of a tuple as arguments to a function in...

It is an ordered collection of objects. The order in which you specify the elements when you define a list is an innate characteristic of that list and is maintained for that list’s lifetime. (You will see a Python data type that is not ordered in the next tutorial on dictionaries.)...
When you’re unpacking a tuple, the number of variables on the left must match the number of values in the tuple. Otherwise, you get a ValueError exception: Python >>> s1, s2, s3 = t Traceback (most recent call last): ... ValueError: too many values to unpack (expected 3) >>...
