Is there a way to combine these 2 loops?

Is there a way to combine these two loops to make it more efficient?

for i in range(n):
    for j in range(i + 1, n + 1):
        print(i, j)

Thanks!

Your code is efficient enough with respect to fact that it is understandable and readable to others hence it is recommended.

However If you are looking for a one liner in python then you can use the following one but I strongly do not recommend it as it only makes the code more un-readable and only adds a headache to others

n = 10
print(' \n'.join('{} {}'.format(*item) for item in [ (i,j) for i in range(n) for j in range(i+1,n+1) ]   ) )

This prints out the exact same output as the code that you have provided.
