python split array into equal length values

I am new to python. I have a list of arbitrary length long int values, and I need to split it up into equal size value. I tried so many ways to do this but it is not printing in correct format.

I defined a array called

arr = [10816446963217280179219841728017921984108164469632
928047221121299210511552129921051155292804722112
50562677440755267009927552670099250562677440
23552216364842368604561924236860456192235522163648
179217208962112891264211289126417921720896
30081517568473642615684736426156830081517568
2624284224185650156818565015682624284224
5765318451245216051245216057653184
288020416028163121792281631217922880204160
];

I have an API that will return an array value. I will use that output and i do this operation:

arr = [1081........
.................];
for i in range(0, len(arr), 8):
print " ".join(map(str,arr[i:i + 8]))

2880 204160 2816 3121792 2816 3121792 2880 204160

I need to print values like this:

  a      b      c        d        e      f        g       h
10816  4469632 17280  17921984  17280  17921984 10816  4469632
9280   4722112 12992  10511552  12992  10511552 9280   4722112
5056   2677440 7552   700992    7552   6700992  5056   2677440
23552  2163648 42368  60456192  42368  60456192 23552  2163648
1792   1720896 2112   891264    2112   891264   1792   1720896
3008   1517568 4736   4261568   4736   4261568  3008   1517568

2880   204160  2816   3121792   2816   3121792  2880   204160

I tried with '\t' like 

 for i in range(0, len(arr), 8):
 print "\t".join(map(str,arr[i:i + 8]))

but it is not printing properly please help me to do this. Thanks in advance.

Using str.format you can align your values. <N will left align and fill to N characters, >N will right align and ^N will format between and fill left and right side until N characters.

for i in range(0, len(arr), 8):
    for item in arr[i:i+8]:
        print('{:<8}'.format(item), end = ' ')
    print()

Or more compact

for i in range(0, len(arr), 8):
    print(' '.join('{:<8}'.format(item) for item in arr[i:i+8]))

# Output
10816    4469632  17280    17921984 17280    17921984 10816    4469632
