Python Regular expression verifies whether it is a prime number

CODE:

Import rewhile True: number    = Int (input (' input number (0 to quit): ')]    if number = = 0: Break    subject = '. Join ([Str ((1)) for a in range (number)])    reobj = Re.compile (r "^1?$|^ (11+?)  \1+$ ")    if Reobj.search (subject):        print" Number%s is not prime number! "% number    else:        print" number%s is A prime number! "% number

RESULT:

Input Number (0 to quit): 8number 8 are not prime number! Input Number (0 to quit): 11number-a prime number! Input Number (0 to quit): 1number 1 are not prime number! Input Number (0 to quit): 2number 2 is a prime number! Input Number (0 to quit): 3number 3 is a prime number! Input Number (0 to quit): 0
