Question

Create a program (or set of programs) which accomplish the following for each complex data type (list,tuple,set,frozenset, dictionary):

• create the item with at least 4 elements
• Append an element
• Remove an element
• Insert an element in the middle somewhere
• Append another array of the same data type
• Append another array of a different data type (for example, if you have a dictionary, append a set or tuples

And do the following:

• Output the results after each step.
• Report and explain any errors (if a line of code generates an error, comment it out along with a comment on what the error was and your reasons for that error)
• Create a range of negative numbers
• Create a range of positive even numbers
• Insert a range into each data type that would allow it

Turn in:

• All source code
• Execution of your program(s)
• Explanation of each error you ran into

Answer 1

1. Using List

• Insert 4 elements in the list

• Appending a new element

• Insert an element in the middle

• Appending another array of the same datatype

• Appending another array of different datatype

• remove an element from a list

2. Using tuple

• Insert 4 elements in the tuple

• Insert another element in the tuple

You can't insert a new element in an existing tuple because it's tuple property that it's unchangeable. And if you want to add a new element then, we can create a new tuple and rename it as the previous tuple.

• Insert an element at the given index

As we know tuple is unchangeable so, we can't enter a new element in the tuple but, if we really want to do so then we can create a new tuple through slicing and add a new element at a given index and rename it as the previous tuple.

• Insert another element of the same datatype

As I said above tuples are unchangeable so we can't modify the existing tuple. But if we really want to add a tuple in a tuple then we can create a new tuple and rename it.

• Insert another element of different datatype

As in previous cases, we can't modify the existing tuple but, we can create a new one and rename it

3. Using Set

• Insert four elements in a set

• Insert another element in a set

• Insert an element at the given index

We can't add an element in the middle of the set. As there is no predefined function and we can't use slicing in the set.

• Insert a set into a set

Since set elements must be hashable, and lists are considered mutable, you cannot add a list to a set. You also cannot add other sets to a set. You can, however, add the elements from lists and sets as demonstrated with the update method.

• Insert a tuple into a set

• Remove given element

4. Using frozenset

As its name suggests, we can't modify it once it's declared. but there are some basic set operations like union, intersection, disjoint, etc.. So it's not possible to modify it.

• Insert four elements into frozenset

It's NOT POSSIBLE to insert, remove, and modify it. So other cases are irrelevant.

5. Using Dictionary

• Insert four elements

• insert new element

• insert at given index

We can't add a new key in between of existing dictionary but, we can create a new dictionary and perform changes in that dictionary

• insert a dictionary into the dictionary

• insert an element of another datatype

• remove an element in the dictionary
