Question

Can you please see what I have done wrong with my program code and explain, This python program is a guess my number program. I can not figure out what I have done wrong. When you enter a letter into the program, its supposed to say "Numbers Only" as a response. I can not seem to figure it out.. instead of an error message.

import random

def menu():
print("\n\n1. You guess the number\n2. You type a number and see if the computer can guess it\n3. Exit")
while True:
c=int(input("Enter your choice: "))
if(c>=1 and c<=3):
return c
else:
print("Enter number between 1 and 3 inclusive.")

def guessingGame():
min_number=1
max_number=10
#set number of guesses = 0
numGuesses=0
rand=random.randint(min_number, max_number)
#prints the header, welcoming the user
print("\nWelcome to the Guess My Number Program!")
#While loop, comparing the users guessed number with the random number.
#If it matches, it will say you guessed it.
while (True):
#use try-block
try:
guess=eval(input("Please try to guess my number between 1 and 10:"))
#check if the guess is less than 0, then continye to beginning of the loop
if(guess<0):
continue;
elif (guess==rand):
#increment the guess count by 1
numGuesses=numGuesses+1
print("You guessed it! It took you ", numGuesses,"attempts")
#break will end the loop once the guess is a match.
#Conditions if the guess is too low or too high to keep guessing
break
elif(guess < rand):
#increment the guess count by 1
numGuesses = numGuesses +1
print("Too low")
else:
#increment the guess count by 1
numGuesses = numGuesses + 1
print("Too high")
except:
#print exception
print("Numbers only!")

def guessingGameComp():
countGuess=0
userNumber=int(input("\nPlease enter a number between 1 and 10 for the computer to guess:"))
while userNumber<1 or userNumber>10:
userNumber=int(input("Guess a number between 1 and 10: "))
while True:
countGuess+=1
compRand = random.randint(1,10)
if(userNumber==compRand):
print("The computer guessed it! It took {} attempts".format(countGuess))
break
elif(userNumber<compRand):
print("The computer guessed {} which is too low".format(compRand))
else:
print("The computer guessed {} which is too high".format(compRand))

def main():
while True:
userChoice=menu()
if userChoice==1:
guessingGame()
elif userChoice==2:
guessingGameComp()
elif userChoice==3:
print("\nThank you for playing the guess the number game!")
break
else:
print("Invalid choice!!!")
