#accept the phone number as input
phone_number=input("Please enter your phone number?")

#temp variable to store only digits

#for loop to interate through the input phone number
for i in phone_number:

#check whether it is digit
if(i.isdigit()):
#if true, add it to temp variable
only_digits+=i

else:
#if false, continue to skip the character
continue

#print only the digits
print(only_digits)
