hi I am a beginner python user studying python is fun and i have learned many thing now a days I am working on a program to find prime numbers and non prime number in a list generated by range function.
i am done with my work the problem is that now i want to print both lists the prime numbers and non prime numbers vertically having 4 columns each and side by side i figured out how to print in four columns but how do i print both list side by side.
if anyone can help i will be very thank ful.
So you want something like this (formatting not to scale!):
Prime Non-prime
2 3 5 7 1 4 6 8
11 13 17 19 9 10 12 14?
yes i want to print like this
Here's one possibility:
def get_four(mylist, index):
retval = ""
for i in range(index, min(index+4, len(mylist))):
retval += str(mylist[i])+"\t"
return retval
def print_two_lists(list1, list2):
for i in range(0, max(len(list1), len(list2)), 4):
print get_four(list1,i),
if get_four(list1,i):
print "\t", get_four(list2,i)
else:
print "\t\t\t\t\t", get_four(list2,i)
>>> l1 = range(20)
>>> l2 = range(30,70,2)
>>>
>>> print_two_lists(l1,l2)
0 1 2 3 30 32 34 36
4 5 6 7 38 40 42 44
8 9 10 11 46 48 50 52
12 13 14 15 54 56 58 60
16 17 18 19 62 64 66 68
>>> l3 = range(30,70)
>>> print_two_lists(l1,l3)
0 1 2 3 30 31 32 33
4 5 6 7 34 35 36 37
8 9 10 11 38 39 40 41
12 13 14 15 42 43 44 45
16 17 18 19 46 47 48 49
50 51 52 53
54 55 56 57
58 59 60 61
62 63 64 65
66 67 68 69Note that splitting the problem into two separate functions actually made the code easier.
