Help with loop

[thanikos]

Hello again
i have this code:

for nr in range(1,100,1):
    print(nr, end=" ")
    if nr == 9:
        print(nr)
    elif nr == 19:
        print(nr)
    elif nr == 29:
        print(nr)
    elif nr == 39:
        print(nr)
    elif nr == 49:
        print(nr)
    elif nr == 59:
        print(nr)
    elif nr == 69:
        print(nr)
    elif nr == 79:
        print(nr)
    elif nr == 89:
        print(nr)
    elif nr == 99:
        print(nr)

This code prints:
1 2 3 4 5 6 7 8 9 9
10 11 12 13 14 15 16 17 18 19 19
20 21 22 23 24 25 26 27 28 29 29
30 31 32 33 34 35 36 37 38 39 39
40 41 42 43 44 45 46 47 48 49 49
50 51 52 53 54 55 56 57 58 59 59
60 61 62 63 64 65 66 67 68 69 69
70 71 72 73 74 75 76 77 78 79 79
80 81 82 83 84 85 86 87 88 89 89
90 91 92 93 94 95 96 97 98 99 99

The problem is that i gett 2 times the same number att the end of the each row
Any ideas how to make it print:

0 1 2 3 4 5 6 7 8 9
10 11 12 13 14 15 16 17 18 19
20 21 22 23 24 25 26 27 28 29
30 31 32 33 34 35 36 37 38 39
40 41 42 43 44 45 46 47 48 49
50 51 52 53 54 55 56 57 58 59
60 61 62 63 64 65 66 67 68 69
70 71 72 73 74 75 76 77 78 79
80 81 82 83 84 85 86 87 88 89
90 91 92 93 94 95 96 97 98 99

Thanks in advance
