Get the frequency of the elements in a list.

Count the number of elements in a list within a specified range.

Check whether a list contains a sub list.

Create a list by concatenating a given list which range goes from 1 to n.
Sample list : ['p', 'q'], n = 5
Sample Output : ['p1', 'q1', 'p2', 'q2', 'p3', 'q3', 'p4', 'q4', 'p5', 'q5']

Find common items from two lists.

Change the position of every n-th value with the (n+1)th in a list.
Sample list: [0, 1, 2, 3, 4, 5]
Expected Output: [1, 0, 3, 2, 5, 4]

Convert a list of multiple integers into a single integer.
Sample list: [11, 33, 50]
Expected Output: 113350

Split a list based on the first character of a word.

Select the odd items of a list.

Insert an element before each element of a list.

Print all elements of a nested lists (each list on a new line) using the print() function.

Split a list every Nth element.
Sample list: ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n']
Expected Output: [['a', 'd', 'g', 'j', 'm'], ['b', 'e', 'h', 'k', 'n'], ['c', 'f', 'i', 'l']]

Create a list with infinite elements.

Concatenate elements of a list.

Convert a string to a list.

Replace the last element in a list with another list.
Sample data : [1, 3, 5, 7, 9, 10], [2, 4, 6, 8]
Expected Output: [1, 3, 5, 7, 9, 2, 4, 6, 8]

Check if the n-th element exists in a given list.

Find a tuple with the smallest second index value from a list of tuples.

Insert a given string at the beginning of all items in a list.
Sample list: [1,2,3,4], string: emp
Expected output: ['emp1', 'emp2', 'emp3', 'emp4']

Find the list in a list of lists whose sum of elements is the highest.
Sample lists: [1,2,3], [4,5,6], [10,11,12], [7,8,9]
Expected Output: [10, 11, 12]

Find all the values in a list are greater than a specified number.

Extend a list without append.
Sample data: [10, 20, 30]
[40, 50, 60]
Expected output: [40, 50, 60, 10, 20, 30]

Remove duplicates from a list of lists.
Sample list : [[10, 20], [40], [30, 56, 25], [10, 20], [33], [40]]
New List : [[10, 20], [30, 56, 25], [33], [40]]

Prepare two files for your post. The first file should be a text file containing your Python solution. The second file should contain your output file(txt file).

Needs to have a separate output file that shows the outputs of the code.

Summary:

Problems based on list :

1) sum - all all elements

2) Multiply - all the element

3) largest - using max() in list

4) Smallest - using min() in list

5) Without duplicates - Convert the list to dictionary as list element key => convert back to list (or else use set())

6)empty - Check list length - if 0 empty else not empty

7)copy list - using = operator

8)check string len - len() if len()>8 display the word

9) common - check if atleast one element in list 2 return True

10) remove index 5,4,0 - using pop(index) {Remove from the larger index - if you remove from smallest the index value will change}

11)After removing even numbers (check for remainder if divided by 2

12) shuffle list - use random.shuffle

13)difference between lists- If a number not common then display

14)list to string => "".join() method ; "" =without space

15)Element at index => index() method

16) Append list1+list2

17) Random number - use random.choice()

18) second smallest - remove first smallest and then find the smallest => second smallest using min()

19) second largest - remove first largest and then find the max()

20) Unique number use set() or from dictionary

21) Frequency of elements - generate dictionary with list values as keys - Iterate and increment the count for each key

22)Number within range - check if num with range and increment count min<number<max

23) check all values of subset in the listset and return True or False

24) add the str and integer by converting the integer

25) common items - And of set of both lists
