Create a file called contacts.py, implement a program that prompts the user to select a choice between these 5 options. Add contact (1), Delete Contact (2) Save Contact(3), show all contact (4), exit program (5). Contact info should be saved in a separate read/write file. If user inputs number (1) on the keyboard, then prompt them to input the name and number of the contact. If user selects (2), delete all contacts or show an error if there are no contacts saved to file. If user inputs (3) save the contact and loop the choice of the 5 options until user inputs (5) to exit. If user inputs (4) print out the saved contacts to the screen neatly, Name, Number(newline). if user inputs 5 then exit the program. If the user inputs a number not shown then give an error message and ask them to input a valid number.  Please code in python, preferably using case statements to complete

Lab Tasks – complete these Use the information provided here, in the slideshow and in chapter 12 of our text to do the following exercise.   Step 1: On the desktop or wherever you will be saving your java program, use notepador other basic text editor (NOT WORD) to create a .txt file.  In this file, type out a list of 10 integers (one on each line or with a space between each). Save. Do this manually.  Not with Java.   Step 2. Now write a program with the following: 1) In the program creating a File object that connects to the .txt file that you just created. 2) Add code that will check if the file exists and if it doesn’t, it will create it.  (Yes, we know it definitely exists but do this part anyway.) 3) Set up a Scanner so that you can read the values from the file and print them to the screen using a loop.  You will probably need to use the .hasNext() method. Also, you may want to set up a counter to keep track of how many values there are for future use. (Note that the .length()…

step 1: Write a python program that will ask the user for their grocery list, one item at a time, and will write it to a file called groceries.txt.  The program should create a new file called groceries.txt that will contain all of the user’s groceries when opened. Step 2: Modify the python program that creates a groceries.txt file so that if the user’s favourite fruit is not on the list, the program will append it to the end of groceries.txt file.

Create a main( ) java file to perform the required tasks. Validate a user’s input (a menu option) to ensure its validity. Test and document your program to make sure that all of the required tasks are met. The main( ) creates a menu for a bank manager and a bank customer. For a bank manager, he/she can add information of bank customers and display all customer records. For a bank customer, he/she can make a deposit to a bank account and withdraw money from the account. Hint: The main ( ) could have a static method that allows a bank manager to add customers’ information to a text file. The information consists of Customer ID, Name (full name), and Email Address. Note that a loop should be used to perform the manager's task. As a result from the process, a text file "BankCustInfo.txt" is created. Also, the main( ) could have another static method that allows the bank manager to display all customer records to the screen. Create a class, BankCustomer, that contains attributes such as…
