You want to search the string for the regex \d{6,}  (that is, 6 or more
digits), and then print the matchobject, like so:

strings = [ '1234spam', '123456eggs', 'spam1234567toast', '12345678' ]

for string in strings:
    match = re.search( "(\d{6,})", string )
    if match: print match.group(1)

This prints

123456
1234567
12345678
