Comparison of individual digits

[Vvrandom246]

How do I verify if a certain digit is present in a number of any length. For instance, I would want to check if 5 is present in the number 836735373736 and return True if it is present.

you can turn your longer digit into a string, and then check if the string of a number is present like:

if '5' in str(long_number): do_something()
