Number guessing game

The player enters 4 digit number, and the computer tells the player how many(but not which) of the 4 digits are correct.

Number changes randomly every time, when new game starts.

E.g.

Guess the number in few tries as possible

Enter the number :      1234
Enter the number :      4567
*
Enter the number :      7533
***
Enter the number :      7593
you used 25 chances, to guess.

CODE

#imports required for validation, i was using older python version for print, i used below import

from __future__ import print_function

import re

from random import randint

print ("Guess the number in few tries as possible\n");

number=[]

inp=str(randint(0000,9999))

for x in inp:

        number.append(x)

check = True

count=0

#loop until guess is correct

while check == True:

        guess=[]

        input=raw_input("\nEnter the number :\t");

        count+=1

#validation if the input is numeric 

        if not re.match("^[0-9]*$", input):

                print ("\nError! Only numeric value allowed")

                continue

# validation if the number is 4 digit longs or not

        if len(input) != 4:

                print ("\nError! Must be 4 digit long number")

                continue

        for x in input:

                guess.append(x)

        if guess == number:

                check = False

                break

        for i in range(4):

                if number[i] == guess[i]:

                        print ("*", end='')

print ("\nYou used {0} chances, to guess".format(count))
