Question
Using Python
The Soundex
There are several different algorithms for Soundex. Using Python, this online interpreter, and the below listed requirements, create an application that will produce a Soundex-like code based on user-entered string:
- The first letter of the word is the first letter of the Soundex code.
- Remove or ignore all letters a, e, i, o, u, h, y, and w.
- Replace the letters that remain, as follows:
Replace this: |
With this: |
b, f, p, and v |
1 |
c, g, j, k, q, s, x, and z |
2 |
d and t |
3 |
l |
4 |
m and n |
5 |
R |
6 |
- If two or more digits are identical (e.g., 11, 222), only keep the first digit.
- Choose the first 3 digits, and append to the first letter from Step 1.
- If you only have 1 or 2 digits, append 0s at the end for the final code.

- exercise3.py x 1 Your code goes here... Guide Collapse Strings -> Coding Exercises - Strings Exercise 3 Exercise 3 Problem Write a program that accepts input from the user. Create another string that contains either a u, 1, or for each character of the original string. Use u when the character is uppercase, and use I when the character is lowercase. If the character is neither uppercase or lowercase, use. Print the second string. Important, do not put a prompt when asking for user input. Just use input(). Adding a prompt will cause your program to not pass the tests. Expected Output • If the user inputs cat, then the output will be: cat 111 • If the user inputs HouSE, then the output will be: HouSE ulluu Code Visualizer TRY IT Reminder, do not put a prompt when collecting user input. Just use input Check It! (1 left)arrow_forwardStrings are made up of a sequence of individual characters True or false? In python.arrow_forwardRecognizing strings based on a set of restrictions is a common computational problem. A Slop is a string of characters that has certain properties. Your program will read in strings of characters and output whether or not they are Slops. A Slip is a character string that has the following properties: Its first character is either a 'D' or an 'E' The first character is followed by a string of one or more 'F's The string of one or more 'F's is followed by either a Slip or a 'G' The Slip or 'G' that follows the F's ends the Slip. For example, DFFEFFFG is a Slip since it has a 'D' for its first character, followed by a string of two F's, and ended by the Slip 'EFFFG' Nothing else is a Slip A Slap is a character string that has the following properties: Its first character is an 'A' If it is a two-character Slap then its second and last character is an 'H' If it is not a two-character Slap, then it is in one of these two forms: 'A' followed by 'B' followed by a Slap, followed by a 'C'…arrow_forward
- Design a program with an algorithm that will take a string from the user and then decide if each character in that string is unique. For example, if you ask the user to enter a string and that user enters the world ‘hello’, the result of the algorithm implementedshould return ‘false’ or ‘not unique’. If the user enters a string such as the word ‘phone’ the program will return ‘true’ or ‘unique’ since every character in the word phone is unique and is not repeated. An example of this program follows: Output should show as : enter a string rizma This string has all the unique characters would u like to continue?(y for yes n for no) y Enter a string waali This string is not unique Your code should work for all strings and essentially all characters, as many examples will be tested.arrow_forwardUsing python, please explain 1: A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. A positive integer greater than 1 is composite if it is not prime. Write a program that asks the user to enter an integer greater than 1, then displays all of the prime numbers that are less than or equal to the number entered The program should work as follows: Once the user has entered a number, the program should populate a list with all of the integers from 2 up through the value entered. The program should then use a loop to step through the list. The loop should pass each element to a function that displays the element whether it is a prime number.arrow_forwardIN PYTHON: Given a string representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212. Ex: If the input is: 8005551212 the output is: (800) 555-1212 Hint: Use string slicing operators. 18005551212 is not allowed.arrow_forward
- for python programming make a program, that has a function that takes in a string argument and prints a sentence indicating the shortest word in that string. If there is more than one word print only the first. Your print statement should read: “The shortest word is x” Where x = the shortest word. The word should be all uppercase.arrow_forwardIn python: The isUpper method converts a string to all uppercase characters True Falsearrow_forwardWrite a JAVASCRIPT code to repeat the given string to n times and add to it the original string without using loops concat, + operator. for example:- n = 4 given string:- Programmer Output:- ProgrammerProgrammerProgrammerProgrammerarrow_forward
