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[limindex:lim+index]) lim += index custom_print(primes, 10)
I hope this helps.
