How to compare elements in multiple lists - list

Question

Lets say we have a list that is comprised of a range of numbers:
list_1 = [] # all numbers between a range
for num in range(0,1000):
if num > 0:
list_1.append(num)
Now we want to seperate some numbers from this list, for example, primes:
list_2 = [] # all prime numbers in list_1
for num in list_1:
if num > 1:
for i in range(2,num):
if (num % i) == 0:
break
else:
list_2.append(num)
Now we want to seperate the list even further, and we notice that prime numbers end in either a 1, 3, 7, or 9. So we tell our program to seperate the primes that end in a certain digit:
list_3 = [] # all prime numbers in list_1 that end in the last digit 1
list_4 = [] # all prime numbers in list_1 that end in the last digit 3
list_5 = [] # all prime numbers in list_1 that end in the last digit 7
list_6 = [] # all prime numbers in list_1 that end in the last digit 9
for num in list_2:
lastdigit = int(repr(num)[-1])
if lastdigit == 1:
list_3.append(num)
elif lastdigit == 3:
list_4.append(num)
elif lastdigit == 7:
list_5.append(num)
elif lastdigit == 9:
list_6.append(num)
What we want to do is to define a function that compares the elements of list_2 with list_3 through list_6. The purpose would be to create uniquely named lists that group the primes from list_2 into list that begin and end with groups of the same digit. For instance if we run the code we see:
[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, 503, 509, 521, 523, 541, 547, 557, 563, 569, 571, 577, 587, 593, 599, 601, 607, 613, 617, 619, 631, 641, 643, 647, 653, 659, 661, 673, 677, 683, 691, 701, 709, 719, 727, 733, 739, 743, 751, 757, 761, 769, 773, 787, 797, 809, 811, 821, 823, 827, 829, 839, 853, 857, 859, 863, 877, 881, 883, 887, 907, 911, 919, 929, 937, 941, 947, 953, 967, 971, 977, 983, 991, 997]
We can see on this list that there are prime numbers that end in the same digit and have another number ending in the same digit for instance 181, 191.
If we look at the list further down we can see another instance where 241, 251.
What we want our list to look like is:
list1_1 = [181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251]
And we want to do this for all numbers in our list of primes. How do we go about doing that? I'm new to python and just trying to understand how to manipulate variables and lists and to compare information between lists for the purpose of computation in number theory. Thanks for your help.
