Question

"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings. For each match, add one point to user_score. Upon a mismatch, end the game.
Sample output with inputs: 'RRGBRYYBGY' 'RRGBBRYBGY'
User score: 4
in python please

Answer 1

Answer:

import random

validletters=["R", "G", "B", "Y"]

input1 = ""

for i in range(1,11):

     input1 = input1 + random.choice(validletters)

input2 = input("Input String 2: ")

if len(input2) != 10:

     print("Invalid Length")

else:

     user_score = 0

     for i in range(0,10):

           if(input1[i] == input2[i]):

                 user_score = user_score + 1

           else:

                 break

     print("String: "+input1)

     print("Guess: "+input2)

     print("User Score: "+str(user_score))

Explanation:

The code assumes that user input will always be R, G, B or Y

The next two lines get two string user inputs

import random

This lists the valid letters

validletters=["R", "G", "B", "Y"]

This initializes an empty string

input1 = ""

The following iteration generates the input string of 10 characters

for i in range(1,11):

     input1 = input1 + random.choice(validletters)

This prompts user for input string

input2 = input("Input String 2: ")

This checks if input string is up to length of 10

if len(input2) != 10:

If yes, it prints invalid length

     print("Invalid Length")

else:

If otherwise, user_score is initialized to 0

     user_score = 0

The following iteration checks for matching characters in both strings

     for i in range(0,10):

           if(input1[i] == input2[i]):

                 user_score = user_score + 1  This increments user_score by 1 if there is a match

           else:

                 break  This ends the program if there is no match

The next three lines print the strings and the user score

     print("String: "+input1)

     print("Guess: "+input2)

     print("User Score: "+str(user_score))

Answer 2

import random

letters=["R", "G", "B", "Y"]

i = 0

to_guess = ""

while i < 10:

   to_guess += random.choice(letters)

   i += 1

print("Simon says "+to_guess)

user_score = 0

user = input()

for x in range(0, len(to_guess)):

   try:

       if user[x] == to_guess[x]:

           user_score += 1

       else:

           break

   except IndexError:

       break

print("User score: "+str(user_score))

I hope this helps!
