How do I make a long list print in segments?

I'm trying to learn python by writing code I'm interested in, currently I want to list all of the primes up to a number of my choice at runtime. However, when I print the primes they just all get blurted out on one line. If you enter a big number this gets really really long. How can I make it so that my print always does like 10 indices then starts a new line?

Note: this is extremely verbose just for debugging purposes.

My code:

``````primes = []
numberToGoTo = int(input("Find primes up to what number?\n"))

for i in range(2, numberToGoTo):
for j in range(2, i):
print("Checking to see if {} is a prime.  Current divisor: {}".format(i, j))
if i % j == 0 and j > 1 and j < i:
print("{} is not prime".format(i))
break
else:
print("{} is a prime! Adding to list.".format(i))
primes.append(i)
else:
#number of primes
print(len(primes))
#list all primes
print(primes)
``````

You can use create custom print function to do this.

``````def custom_print(primes, index):
index /= 2
lim = index
while(lim <= len(primes)):
print(primes[lim-index:lim+index])
lim += index

custom_print(primes, 10)
``````

I hope this helps.
