Please give me feedback on how I can possibly improve this Python code I created for "Codebreaker", a modified version of the game "Mastermind". No AI please!

import random

import time

# Function to generate a random $4-$digit code with numbers from $1-8($no repeats$)$

def generate$\_$secret$\_$code$()$:

digits $=$ list$($range$(1,9))$

random.shuffle$($digits$)$

secret$\_$code $=$ digits$[$:$4]$

return secret$\_$code

# Function to check if the player's guess is valid

def is$\_$valid$\_$guess$($guess$)$:

if len$($guess$)!=4$:

print$("$Oops$!$ The guess should be exactly $4$ digits long. Try again."$)$

return False

if not all$($char$.$isdigit$()$ and $1<=$ int$($char$)<=8$ for char in guess$)$:

print$("$Invalid input! Only digits from $1$ to $8$ are allowed."$)$

return False

if len$($set$($guess$))!=4$:

print$("$No repeats! The digits in your guess must be unique."$)$

return False

return True

# Function to calculate X $($correct digit & position$)$ and O $($correct digit, wrong position$)$

def evaluate$\_$guess$($secret$\_$code, guess$)$:

X $=$ sum$([1$ for i in range$(4)$ if secret$\_$code$[$i$]==$ int$($guess$[$i$])])$

O $=$ sum$([1$ for i in range$(4)$ if int$($guess$[$i$])$ in secret$\_$code and secret$\_$code$[$i$]!=$ int$($guess$[$i$])])$

return X$,$ O
