python MCQ 46-60

Question 46. create a script that generates 26 txt files.

Question 47. Write a script that extracts letters from the 26 text file and put the letters in a list.

Question 48. Create a script that iterates through text files and checks if strings p, y, t, h, o, or n are found in the content of the text file. If any of those strings is found, append that string to a list.

Question 48.1. The script is supposed to print out letter "e" if the letter is in string "Hello", but it doesn't. Please try to fix the script.

Question 49. The code is supposed to get some input from the user, but instead it produces an error. Please try to understand the error and then fix it.

Question 50. The code produces an error. Please understand the error and try to fix it

Answer 1:

age = int(input("What's your age? "))
                            age_last_year = age - 1
                            print("Last year you were %s." % age_last_year)
                            Explanation 1:
                            
                            As you can see we applied an int  function to the input  function. That converts user input to an integer right away.
                            
                            Answer 2: 
                            
                            age = input("What's your age? ")
                            age_last_year = int(age) - 1
                            print("Last year you were %s." % age_last_year)
                            Explanation 2:
                            
                            In this alternative solution we applied the int  function in the line where the math operation is taking place. This could be useful 
                            if you're intending to use the user input value as a string in other parts of your script, 
                            so you don't want to convert it to an integer directly.

Question 51. The code produces an error. Please understand the error and try to fix it

Question 52. The code is supposed to ask the user to enter their name and surname and then it prints out those user submitted values. Instead, the code throws a TypeError. Please fix it so that the expected output is printed out.

Question 53. Print out the last name of the second employee.

Question 54. Please update the dictionary by changing the last name of the second employee from Smith to Smooth or to whatever takes your fancy.

Question 55. Please add a new employee to the dictionary.

Expected output: 
            
                                          {'employees': [{'firstName': 'John', 'lastName': 'Doe'},
                                                        {'firstName': 'Anna', 'lastName': 'Smith'},
                                                        {'firstName': 'Peter', 'lastName': 'Jones'},
                                                        {'firstName': 'Albert', 'lastName': 'Bert'}],
                                          'owners': [{'firstName': 'Jack', 'lastName': 'Petter'},
                                                      {'firstName': 'Jessy', 'lastName': 'Petter'}]}

Question 56. Store the dictionary in a json file.

import json

d = {"employees":[{"firstName": "John", "lastName": "Doe"},
                                              {"firstName": "Anna", "lastName": "Smith"},
                                              {"firstName": "Peter", "lastName": "Jones"}],
                              "owners":[{"firstName": "Jack", "lastName": "Petter"},
                                        {"firstName": "Jessy", "lastName": "Petter"}]}
                              
                              with open("company1.json", "w") as file:
                                  json.dump(d, file, indent=4, sort_keys=True)
                              Explanation:
                              
                              As you can see we created the json file using the standard file handling method, but then we used json.
                              dump  which makes it easy to write the dictionary content to the file. 
                              
                              indent=4  will create 4 white spaces to indent the different levels of the dictionary items and sort_keys=True  
                              tells Python to preserve the order of the dictionary thrown in the file.

Question 57. Please download the file in the attachment and use Python to print out its content.

Question 58. Please download the json file in the attachment and use Python to add a new employee to the content of the file so that the file looks like in the expected output below.

Expected output:

Question 59. Please complete the code so that it prints out the expected output.

Question 60. Create a program that prints Hello repeatedly.
