 Improving the Caesar cipher Improving the Caesar Cipher Level of difficulty Hard Pre-requisites Module 1.11.1.1, Module 1.11.1.2 Objectives improving the student's skills in operating with strings; converting characters into ASCII code, and vice versa. Scenario You are already familiar with the Caesar cipher, and this is why we want you to improve the code we showed you recently. The original Caesar cipher shifts each character by one: a becomes b , z becomes a , and so on. Let's make it a bit harder, and allow the shifted value to come from the range 1..25 inclusive . Moreover, let the code preserve the letters' case (lower-case letters will remain lower-case) and all non-alphabetical characters should remain untouched. Your task is to write a program which: asks the user for one line of text to encrypt; asks the user for a shift value (an integer number from the range 1..25 - note: you should force the user to enter a valid shift value (don't give up and don't...

 Solution for the Empty Line empty lines in python If you have reached practice 2.5.1.3 Four simple programs, you will notice a challenge in the bottom of the exercise: The code has one important weakness - it displays a bogus result when the user enters an empty line. Can you fix it? Let's see how to fix it. The problem: User may enter an empty line or just press Enter without any data. Solution: In case user entered an empty line = a loop + else We need to keep prompting user to enter data = input() line = input ( "Enter a line of numbers - separate them with spaces: " ) strings = line . split () total = 0 while strings == []: # If line is empty, string.split() will equal []     line = input ( "No data found \n Enter a line of numbers - separate them with spaces: " )     strings = line . split () else :         try :         for substr in strings :             total += float ( sub...

Python Code to make a Seven Led Display Seven LED Display Exactly, what you see in the picture on top is a sample of a seven led display which uses a decimal number from 0-9 for as many digits as needed. Also, alpha characters (letters and symbols)can be used. Figure.1 Why is it called "Seven Segment"? Simply because it contains seven elements as shown in Figure.1. The seven segments are arranged as a rectangle of two vertical segments on each side with one horizontal segment on the top, middle, and bottom. The optional decimal point (an "eighth segment", referred to as DP) is used for the display of non-integer numbers. Figure.2 As shown in Figure.2, this is how the numbers are shown. For example, " 0 " means all segments from A-G are led(shown), " 1 " means B and C are shown. And below table shows us the plan of our code Seven Segments-LED display If you want to get a full idea about How Seven Segment LED Display works, you will find a slidesho...
