find primers and palindromes in python : A palindromic prime is a prime number that is also palindromic. 
For example, 131 is a prime and also a palindromic prime, as are 313 and 757. 

I need to write a function that displays the first n palindromic prime numbers. 
Display 10 numbers per line and align the numbers properly, as follows:

    2     3     5     7    11   101   131   151   181   191
    313   353   373   383   727   757   787   797   919   929



my code is:

    def paliPrime(n):
    a=0
    b=n
    a+=1
    for i in range(a,b):
        paliPrime=True
        if str(i) == str(i)[::-1]:
            if i>2:
                for a in range(2,i):
                    if i%a==0:
                        paliPrime=False
                        break
                if paliPrime:
                    print i


the code works but not in the way i wanted:

    >>> 
    >>> paliPrime(10)
    3
    5
    7
    >>> 

And what I want is a function that displays the first n palindromic prime numbers. It should display 10 numbers per line and align the numbers properly.
