- 1. Random numbers File: random_numbers.py (Quick note: NEVER name your files the same as a Python module. If you call this file random.py it won't let you import the real random.) (Another quick note: Don't let yourself get stuck on something for too long. If one part of one question starts taking you too long, just leave it, move on and come back to it later.) Write a complete Python program that ask the user for quantity of random numbers and a maximum, then generates and store that many numbers between 0 and the maximum. When you've got this part working, add the following interesting additions: minimum maximum random choice from existing list (Hint: if there are 7 numbers it will be a number at a random index 0-6) the list reversed* the list sorted* Note*: Python's .reverse() and .sort() list methods do NOT return the reversed or sorted list... they modify the list in place.So, if you write something like: print(numbers.sort()) You will not get what you expect. You'll sort the…##Please help with this practice programming problem..... ##if you can't answer the whole problem, please at least try helping with the file handling part thank youPLEASE ASK THE USER IF THEY WOULD LIKE TO WRITE INTO THE FILE IF THEY CHOOSE NOT TO DELETE THE FILE, AND WRITE IT INTO THE FILE Write a complete java program that: asks the user for a filename tests whether the file exists and tells the user if it does exist ask the user whether it should be deleted.

Due to the pandemic During the virus outbreak, Jojo received many requests to analyze whether there was any viral DNA in the patient. This number of requests made Jojo's job even more difficult. Therefore, Jojo ask Lili who is a programmer for help to make a program that can read the file containing the patient's DNA data and viral DNA and then match them. If on the patient's DNA found the exact same string pattern, then write to the index screen the found DNA. Data contained in the file testdata.in Input Format The first line of input is the number of test cases TThe second row and so on as many as T rows are the S1 string of patient DNA and the S2 string of viral DNA separated by spaces Output Format The array index found the same string pattern.

When regular customers call Perfect Pizza on the phone, they are asked their phone number. When the number is typed into a computer, the name, address, and last order date is automatically brought up on the screen. Once the order is taken, the total, including tax and delivery, is calculated. Then the order is given to the cook. A receipt is printed. Occasionally, special offers (coupons) are printed so the customer can get a discount. Drivers who make deliveries give customers a copy of the receipt and a coupon (if any). Weekly totals are kept for comparison with last year’s performance. ⦁ Write a summary of business activities for taking an order at Perfect Pizza.⦁ Draw a context-level data flow diagram for Perfect Pizza⦁ Explode the context-level diagram in b showing all the major processes.

Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, you should come up with a simple one of your own. For example, you could read the first file one character at a time, and add 10 to the character code of each character before it is written to the second file. - Challenge 8 Write a program that decrypts the file produced by the program in Programming Challenge 7. The decryption program should read the contents of the coded file, restore the data to its original state, and write it to another file
