Step by step
Solved in 3 steps
- Why is it useful to store information with different data types? When do you choose to use a list over a dictionary? Other than lists, how are the other built-in data types in Python usefulplease solution Python language using list 1. Create a program that allows you to enter student information (name, gender, and total grade) into a student class. Enter at least 10 students, and then list the students who passed and which students had failed. Also, print a list of female students and print for a male student.Find an example of a Python program on the Web that uses a dictionary in the code and share it. Post the link for the site. What is a Python dictionary? When should you use a dictionary rather than a list in Python?.What is happening in your programming example? Describe it in English as an algorithm.
- How do you measure the memory usage of a dictionary in Python? What factors influence the memory footprint of a dictionary?Write a program in python that creates an empty dictionary and fills it with information about a person (for example, name, age, gender, telephone number, email, etc.) that the user is prompted. Every time you add a new data the contents of the dictionary should be printed.python onlystart from here: def ask_for_age(): age = int(input('Enter the age of a family member: ')) return age
- Using the following information, make a Python dictionary called "Contacts" that can print out all the phone numbers with the names of the people who own them: Nana – 0905678999 Mikael - 0922321 Zara – 09994567890 Allan - 09556211 Output should be like: {'Nana': 0905678999, 'Mikael': 0922321, 'Zara': 09994567890, 'Allan': 09556211}Python coding language Create a static dictionary with a number of users and with the following values: First name Last name Email address Password Ask the user for: 5. Email address 6. Password Loop (for()) through the dictionary and if (if()) the user is found print the following: 7. Hello, first name last name you have successfully logged in 8. Notify the user if the password and email address are wrong 9. Additional challenge: if you want the program to keep asking for a username and password when the combination is wrong, you will need a while() loop. 10. Save the file as assignment03yourlastname.pyHow can you Update Python Dictionary?
- Using Python, write a program which opens a text file and loads the data into a dictionary where the key is the line # from the file and the value is the line of text from the file. For instance, if the file looks like: Hello,Welcome to Introduction to Big Data It is good to meet everyone.Hope you enjoy the class. The dictionary should look like: KEY VALUE 1 Hello, 2 Welcome to Introduction to Big Data 3 It is good to meet everyone. 4 Hope you enjoy the class. Then change it to a list and reverse the order of the lines of text and save it back to a new text file.A python dictionary, Bank, is created to keep track of the Current Account and the Savings Account for each client in a bank. While the first item in the list is for the current account, the second item is for the savings account. The client’s name acts as the key for this dictionary.Bank = {"Apple":[100.0, 1500.0],"Bobby":[200.0, 4000.0],"Cathy":[150.0, 3500.0],"David":[300.0, 2500.0]}Write the following functions for the dictionary Bank to maintain the clients’ current and savings accounts.1. Function printBank( ): print out the contents of the dictionary Bank2. Function deposit(Name, account_type, amount): deposit the amount of money to the account specified by the account_type under the client’s name.3. Function withdraw(Name, account_type, amount): withdraw the amount of moneyfrom the account specified by the account_type under the client’s name.4. Function creatAccount(Name): create a new entry in the dictionary and initialize both the current and savings accounts to 0.0 under…A Python dictionary that returns a list of values for each key. The dictionary will contain information about my favorite books, including the title, author, and year of publication. The key will be the title of the book, and the values will be a list containing the author and the year of publication. favorite_books = { "The Great Gatsby": ["F. Scott Fitzgerald", 1925], "To Kill a Mockingbird": ["Harper Lee", 1960], "1984": ["George Orwell", 1949]} NOTE: You can replace the book details as your need in above code. Next, modify the invert_dict function from Section 11.5 of "Think Python" to invert my dictionary. The modified function will need to turn each of the list items into separate keys in the inverted dictionary. def invert_dict(d): inverse = dict() for key in d: vals = d[key] for val in vals: if val not in inverse: inverse[val] = [key] else: inverse[val].append(key) return inverse Here, the…
