Python Program Divisibility with 5

Write a python program to print and count all numbers from 0 to n which are divisible by 5 and having none of the digits being repeated.

def checkRepeatingDigits(numb):

    checkString = str(numb)

    flag = True

    for i in range(len(checkString)-1):

        for j in range(i+1,len(checkString)):

            if checkString[i] == checkString[j]:

                flag = False

                break

        if flag == False:

            break

    return(flag)

n = int(input("Enter the limit:"))

counter = 0

for i in range(n):

    numb = i

    if numb % 5 == 0:

        if checkRepeatingDigits(numb) == True:

            counter +=1

            print(numb)

print("Total number of numbers divisible by 5 and having non-repeating characters =",counter)
