Check if a digit is present in a list of numbers

Question

How can I see if a number contains certain digits?

numbers = [2349523234, 12345123, 12346671, 13246457, 134123431]

for number in numbers:
    if (4 in number):
        print(number + "True")
    else:
        print("False")

Answer 1

You would have to do string comparisons for this

for number in numbers:
    if '4' in str(number):
        print('{} True'.format(number))
    else:
        print('{} False'.format(number))

It isn't really meaningful to ask if the number 4 is "in" another number (unless you have some particular definition of "in" in mind)
