How to check if input is a number, and do something about it if it isn't?

As the title says, I’m trying to make a guessing game for fun. My only problem is figuring out if they did anything besides a flat number (no decimals, negatives, letters). If it is something besides that, it prints something.

import random
import time
streak = 0
numbers = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10"]



while True:
  answer = random.choice(numbers)
  insultlist = ["bro the real answer was " + answer + ", how are you even that bad?", "bro you suck at this, u werent even close. The correct answer was " + answer + "..", "it's the people like you who make me question the future of this planet. The actual answer was " + answer + ".", "lol u suck, the real answer was " + answer + "."]
  insultchoice = random.choice(insultlist)

  guess = input("Type a number between 1 and 10! ")


  if guess == answer:
    print("lol ur lucky, you guessed it correctly.")
    streak = streak + 1
    streakmsg = f"You're at a streak of {streak}."
    print(streakmsg)
    time.sleep(1)
    print("______________________________________________________")

  else:
    print(insultchoice)
    if streak >0:
      loststreak = f"You lost your streak of {streak}."
      print(loststreak)
      streak = 0
    time.sleep(1)
    print("______________________________________________________")
  

I tried using type(guess) and isnumeric, but they just ended up printing the same thing even if it is or isnt a number.

>Solution :

You can just check if the string guess is numeric, and is more efficient than the regex solution.

if not guess.isnumeric():
    print("You didn't enter a number")
