make sure the code follows template code # Topics: Handling exceptions, list## List manipulation with exception handling!In this assignment, you are given one list to perform different types of operations in each function. All the functions are provided, and you need to find out the kind of exceptions that can happen while performing different operations on the elements, and your task is to fill out the code with Python exception handling mechanisms wherever appropriate.## Lab Scenario:1. In this lab, a list is provided that you need to obtain from an input file. The elements of the list are separated with a comma. The code is provided to get the list from the file. The format of the file is as follows: `1,2,3,"NA",0,10`2. The following functions are provided. You need to fill out the exception handling blocks in the appropriate places.| Function name | Parameter: data type | Return: data type | Description ||-----------------------|----------------------|--------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------|| summation(sequence) | sequence: python list| Total summation of numeric elements: float | takes a list ‘sequence’ and returns the summation of the sequence. || reciprocal(n) | n: any python data type | Reciprocal of n if n is numeric otherwise returns a string: *"Zero and string not allowed"* | gets the list element n and returns the reciprocal of the number. For example: if n is a number then reciprocal of n is 1/n. || getlist(filename) | filename: string | Returns a list of elements if file can be opened otherwise returns False | stores the content of the file ‘filename’ in a list. raises an IOError if the file cannot be open. | ```plaintextdef summation(sequence): """ Input: sequence: python list Return: summation of the numeric elements: int or float """ total_sum = 0 for s in sequence: total_sum += float(s) return total_sumdef reciprocal(n): """ Input: n: int or float Returns: reciprocal of n if n is int or float otherwise returns error message """ return 1/float(n)def getList(filename): """ Input: filename: string Returns: list: content of the file in list if file can be opened otherwise returns false """ f = open(filename) temp = f.readline() return [t.split('\n')[0] for t in temp.split(',')] # returns the sequence def main(): sequence = getList('LA9.txt') if sequence == False: print ("File I/O error") else: print("The sequence is: ", sequence) print ("**** Calculating Summation *****") print (summation(sequence)) print (" **** Calculating Reciprocal *****") for s in sequence: print ('{} : {}'.format(s , reciprocal(s)))6. For this lab, you are expected to use python exception handling mechanism try-except block. Theabove functions are provided, you need to fill out the functions with try-except statements wherever needed. One sample code can be as follows:W/O exception handling (user might enter W/o try-except block some non-number values)x = input("Enter a number: ")print ("You entered a number") try: x = input("Enter a number: ") print ("You entered a number")except: print ("Not a valid number. ")Sample Output for the given Input file:This is just a sample output, you can choose to print other messages as you like, but the code shouldhave exception handling implemented properly so that it gives you the right output.The sequence is: ['1', '2', '3', '"NA"', '0', '10','100.0', '23'] **** Calculating Summation ****Not a number, continue to next element139.0**** Calculating Reciprocal ****1 : 1.02 : 0.53 : 0.333333333

Here we take all three function and discuss which handling is required and why:…

In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia, all ships of top speed and, after the Great Eastern, the biggest ever…

Build Brothers company in C A civil engineering company called Build Brothers has approached you to write a program to help some of their employees with getting their job quicker specially when it comes to calculating different equations in their construction projects. Currently, they use the following PDF to perform all their calculations: http://www.madison-lake.k12.oh.us/userfiles/680/Classes/16192/IED-Review%20Engineering%20Formula%20Sheet.pdf They are willing to develop a small software to calculate all the functions and calculations in the above cheat sheet. They have made this decision to reduce inherent human errors during calculation and improve efficiency. They think that these can be achieved by an “advanced calculator” that allows a user to choose an equation, provide the inputs, and calculate the outputs. Before the company invests on the final product, the have agreed on developing a proof-of-concept first. The idea is that your solution will ‘prove’ that a better…

Which of the following statements is NOT correct? Group of answer choices C++ language provides a set of C++ class templates to implement common data structures, which is known as Standard Template Library (STL); In STL, a map is used to store a collection of entries that consists of keys and their values. Keys must be unique, and values need not be unique; In STL, a set is used to store a collection of elements and it does not allow duplicates; Both set and map class templates in STL are implemented with arrays.
