Answer:
user_score = 0 #user score is initialized to 0
simonPattern = 'RRGBRYYBGY'# stores the sequence of characters in simonPattern
userPattern = input("Enter user pattern: ") # prompts the user to enter user pattern and stores the pattern in userPattern
for x in range(len(simonPattern)): #loops through entire length of simonPattern using x as index variable
if userPattern[x] == simonPattern[x]: # checks if the element at x-th index of userPattern matches the element at x-th index of simonPattern
user_score = user_score + 1 # adds 1 to user score if above if condition evaluates to true
else: #if a mismatch occurs
break #loop break if mismatch occurs
print("User Score:",user_score) #prints the computed user score
Explanation:
The program first declares a simonPattern string variable and assign it a sequence of characters. You can also prompt to enter the Simon pattern as
simonPattern = input("Enter Simon pattern:")
If you want to hard code the values of both simonPattern and userPattern then change the first two statements after user_score =0 statement as:
simonPattern = 'RRGBRYYBGY'
userPattern = 'RRGBBRYBGY'
Now I will explain the working of the for loop.
for x in range(len(simonPattern)):
len method is used which returns the length of the string stored in simonPattern. For example if simonPattern = 'RRGBRYYBGY' then len returns 10
range method is used to generate a sequence of numbers for x. This means value of x starts from 0 and it keeps incrementing to 1 until the length of the simonPattern is reached.
At first iteration:
Let suppose user enters the pattern: RRGBBRYBGY
x starts at index 0. Value of x=0 is less than the length of simonPattern i.e. 10 so the body of loop executes. The body of loop contains the following if statement:
if userPattern[x] == simonPattern[x]:
It matches both the string for the value of x.
if userPattern[0] == simonPattern[0]:
First character (at 0th index) of userPattern is R and in simonPattern is also R so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=1
Next iteration:
x=1
if userPattern[1] == simonPattern[1]:
Second character (at 1st index) of userPattern is R and in simonPattern is also R so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=2
Next iteration:
x=2
if userPattern[2] == simonPattern[2]:
Third character (at 12nd index) of userPattern is G and in simonPattern is also G so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=3
Next iteration:
x=3
if userPattern[3] == simonPattern[3]:
Fourth character (at 3rd index) of userPattern is B and in simonPattern is also B so this statement executes: user_score = user_score + 1 which adds 1 to the user_score. So user_score=4
Next iteration:
x=4
if userPattern[4] == simonPattern[4]:
Fifth character (at 4th index) of userPattern is B and in simonPattern is R so the if part does not execute and program moves to the else part which has a break statement which means the loop break. The next print(user_score) statement print the value of user_score. As user_score=4 computed in above iterations so output is:
User Score: 4
Answer:
The other answer was so close, but the _ was left out so the answer was wrong.
Written in Python:
user_score = 0
simon_pattern = input()
user_pattern = input()
for x in range(len(simon_pattern)):
if user_pattern[x] == simon_pattern[x]:
user_score = user_score + 1
else:
break
print('User score:', user_score)
