Question
Use Python for this question:
Implement a function findMixedCase
- that accepts a single argument, a list of words, and
- returns the index of the first mixed case word in the list, if one exists, (a word is mixed case if it contains both upper and lower case letters), and
- returns -1 if the all words are either upper or lower case
Output for this question is in the attached image:
![>>> findmixedCase( ['Hello','how','are','you'] ) # 'Hello' is mixed case
>>> findmixedcase( ['DUCK', 'duck', 'Goose', 'duck', 'duck', 'DUCK', 'DUCK',
'DUCK', 'duck', 'duck', 'DUCK', 'DUCK']) # 'Goose'
2
>>> findmixedcase( ['DUCK', 'duck', 'goose', 'duck', 'duck', 'DUCK', 'DUCK',
'DUCK', 'duck', 'duck', 'DUCK', 'DUCK']) # 'goose'
2
>>> findmixedcase( ['DUCK', 'duck', 'duck', 'duck', 'DUCK', 'DUCK', 'DUCK',
'duck', 'duck', 'DUCK', 'DUCK']) # no mixed case, all upper or lower

- The function interleave_lists in python takes two parameters, L1 and L2, both lists. Notice that the lists may have different lengths. The function accumulates a new list by appending alternating items from L1 and L2 until one list has been exhausted. The remaining items from the other list are then appended to the end of the new list, and the new list is returned. For example, if L1 = ["hop", "skip", "jump", "rest"] and L2 = ["up", "down"], then the function would return the list: ["hop", "up", "skip", "down", "jump", "rest"]. HINT: Python has a built-in function min() which is helpful here. Initialize accumulator variable newlist to be an empty list Set min_length = min(len(L1), len(L2)), the smaller of the two list lengths Use a for loop to iterate k over range(min_length) to do the first part of this function's work. On each iteration, append to newlist the item from index k in L1, and then append the item from index k in L2 (two appends on each iteration). AFTER the loop…arrow_forwardWrite a function that will accept a list of integers and return the sum of the contents of the list(……if the list contains 1,2,3 it will return 6…..)arrow_forwardprogram- python Write a function called “missing”. Ask the user for a series of integers from 1 to N. Send that list to missing and have it return the list of what numbers are missing. For example, if they enter 1 3 7 10, then you would call missing on that list which returns the list of missing numbers and then you can let them know by printing out the list that they are missing 2 4 5 6 8 9. Test it out on this and show it works. PLEASE USE SET SUBTRACTIONarrow_forward
- Written in python with docstrings if applicable. Thanksarrow_forwardPlease answer quickly In pythonarrow_forwardIn python We have a list (named data) of numbers sorted in ascending order, for example: data = [2, 4, 5, 9, 10, 12, 13, 17, 18, 20] Write a function (named DataVar(data)), which take a list (data) as input parameter and performs the following steps on the list: 1) it finds the mean m of the data (for the given example, it is m = (2 + 4 + 5 + 9 + 10 + 12 + 13 + 17 + 18 + 20)/10 =110/10 = 11). 2) then, it finds the difference of data and m. Essentially, it finds for all data: Diff = data-m For the given example, Diff = [-9, -7, -6, -2, -1, 1, 2, 6, 7, 9]. 3) then, it finds the sum of Diff and 7. Essentially, it finds for all data: Sums = Diff+7 For the given example, Sums = [-2, 0, 1, 5, 6, 8, 9, 13, 14, 16]. 4) then, it finds the square of all the elements of Sums, such that Squares = square of the elements of Sums. For the given example, Squares = [4, 0, 1, 25, 36, 64, 81, 169, 196, 256]. 5) it finds the average of Squares and stores it in result, and returns it. For the given…arrow_forward
- Allow student to insert one arbitrary string. Save the letters of the string into a list. Design and perform the following tasks and display your results: • Summarizing letters in a string. Write a function that receives a string and returns a list of tuples containing the unique letters and their frequencies in the string. Test your function and display each letter with its frequency. Your function should ignore case sensitivity (that is, 'a' and 'A' are the same) and ignore spaces and punctuation. When done, write a statement that says whether the string has all the letters of the alphabet. • Present descriptive statistics and graphs about the string data. • Sorting letters in different order and removing duplicates • Write a code that produces anagrams of a given string. An anagram of a string is another string formed by rearranging the letters in the first. program must accept inputs from a user, performs an operation using a userdefined function which will accept parameters and…arrow_forwardIn this problem, you have available to you a working version of the function round_up described in part (a). It is located in a module named foo. Using the given round_up function, write a function round_up_all that takes a list of integers and MODIFIES the list so that each number is replaced by the result of calling round_up_ on that number. For example, if you run the code, 1st = [43, 137, 99, 501, 300, 275] round_up_all(1st) print(1st) the list would contain the values [100, 200, 100, 600, 300, 300] Do not re-implement the round_up function, just import the food module and use it. Here is the code for the round_up function that can be imported using foo: def round_up(num): if num % 100 == 0 : #if number is complete divisible return num #return orginal num else: return num + (100-(num % 100)) #else add 100-remainder to num, if __name__ == '__main__': print(round_up(234)) print(round_up(465)) print(round_up(400)) print(round_up(89))arrow_forwardI am very confused on how to answer this and any thing will help. Create a function that accepts a single list. Inside the function, have nested for loops (a for loop inside a for loop). The outer for loop iterates through every item in the list. The inner loop iterates through every subitem in item, and prints it. Test the function by passing it the list [ [0, 1, 2], [3, 4, 5], [6, 7, 8] ].arrow_forward
