It is possible to do this program with a single repetition structure

Question

# Print all pairs of numbers in array A whose sum is greater than 10

A = [4,5,2,1,3,7]

for value_1 in A:
for value_2 in A:
total = value_1 + value_2
if (total > 10):
print (value_1, " + ", value_2, " > 10")

Answer 1

I think it's not possible because you have to pick every number in A => for loop and every number should be combined with every number in A => second for loop.

Answer 2

Well, it actually is:

from itertools import combinations
A = [4, 5, 2, 1, 3, 7]
B = combinations(A, 2)
for pair in B:
if pair[0] + pair[1] > 10:
print(pair[0], "+", pair[1], "> 10")

You can also try list comprefensions, but they'll still actually use two iterating constructions.
