Hi thank you for share, which version of python are you using, i am trying to run in 3.5.1 and i am getting "missing parenthesis in call to print", some idea what can it be?

Now it should work with any python version

Code:

# type here desired prefix
IWANT="inc"

#do not change anything after the signal
#BEEP
b58_digits = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'
def base58_encode(n):
l = []
while n > 0:
n, r = divmod(n, 58)
l.insert(0,(b58_digits[r]))
return ''.join(l)

lw=len(IWANT)
result=""

for i in IWANT:
if not i in b58_digits:
print "Address contain non b58 symbol"
exit()

for i in range(16**6):
pk=int(hex(i)+"0"*(8-len(hex(i))) + "0"*44,16)
adr=base58_encode(pk)
if adr[:lw]==IWANT:
result=hex(i)+"0"*(8-len(hex(i))) + "0"*44
break

result_string='base58Prefixes[PUBKEY_ADDRESS] = list_of'
for i in range(1,16):
st=result[i*2:i*2+2]
if st=="00":
break
else:
result_string+="(%d)"%int('0x'+st,16)

result_string+=";"

print(result_string)

It is possible to calculate desired bits without iterating, there is no hashing after adding version byte, so its just a simple math to recalculate from numeration system with base 58 to hex. However looks like for FootyCash developer (https://bitcointalk.org/index.php?topic=1374929.20) it was too hard Wink
