"Number guessing game" in Python

I am new to Python and I have tried to come up with a code for the number guessing game. But I am pretty sure this is not the right way to do it. I am able to get the right output, however, my code is pretty long. Any ideas on using a different logic or to reduce the code size would help.

I also would like to know how to code profile a python code for performance.

I am using IDLE and Python 3.+

```
import random

def main():
while(True):
inputchoice = input("Are you ready? Y/N : ")
if(inputchoice.strip() in ("y","Y","yes","Yes","YES","YEs","yeS","YeS","yEs","yES")):
print("Ok. Lets begin")
randomnumberguessinggame()
break
elif(inputchoice.strip() in ("no","No","NO","nO","n","N")):
print("Let me know when you are ready")
break
else:
print("Invalid Entry. Try again")

def randomnumberguessinggame():
print("Get ready to start guessing")
actualnumber = random.randrange(0,1000)
#print("The number to be guessed is %d"%actualnumber)
flag = True;
while(flag):
try:
guessednumber = int(input("Enter your guess "))
if(guessednumber > actualnumber):
print("That was a wrong guess. Your guess is higher than my number")
while(True):
retry = input("Would you like to try again? Y/N : ")
if(retry.strip() in ("y","Y","yes","Yes","YES","YEs","yeS","YeS","yEs","yES")):
flag = True;
break
elif(retry.strip() in ("no","No","NO","nO","n","N")):
flag = False;
break
else:
print("Invalid Entry. Try again")
elif(guessednumber < actualnumber):
print("That was a wrong guess. Your guess is lower than my number")
while(True):

Advice 1

I would not abuse the user with the question whether he wants to continue; just have a command (say, quit) for quitting the game while still guessing.

Advice 2

randomnumberguessinggame

The Python way is random_number_guessing_game.

Advice 3

You don't have to use parentheses in the branch and loop conditionals.

Summa summarum

I had this in mind:

import random

def main():
    actual_number = random.randrange(0, 1000)
    while True:
        guess = input("Enter your guess: ")

        if guess.strip().lower() == "quit":
            print("Bye!")
            return

        try:
            guess_number = int(guess)
        except ValueError:
            print(guess, "is not an integer!")
            continue

        if guess_number  actual_number:
            print("Your guess is too large.")
        else:
            print(guess_number, "Excellent!")
            return

main()

Hope that helps.
