print two different sequence number

[mantonegro]

Hi all I'm studying python recently and I'm newbie on programming language also
I'm writing a pyhthon code that print two different sequence number, the first one composed with 1,2,3,4,..n the second one with 1,5,9.13,.m
So I'd like to obtain an output like this:

1 1
2 5
3 9
4 13
5 17
....

I've tried with the following "for loop nested" but the result is not what I'm looking for

numeri1 = range(1,10)
numeri2 = range(1,10,4)

for elemento_1 in numeri1:
   for elemento_2 in numeri2:
      if elemento_1 <= elemento_2:
      print (elemento_1, elemento_2)

Infact the output obtained using this code is the following
1 1
1 5
1 9
2 5
2 9
3 5
3 9
4 5
4 9
5 5
5 9
6 9
7 9
8 9
9 9

So..Have you got any suggestion for modify this code to get the correct output?
Anyway is the "for loop nested" the right way or there is another way?
Thanks
