Help with loop

Hello
Any ideas how to do this:
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

Here is my code:
for nr in range(0,100,1):
if nr<10:
print(nr, end=' ')
elif nr<20:
print(nr, end=' ')
elif nr<30:
print(nr, end=' ')
elif nr<40:
print(nr, end=' ')
elif nr<50:
print(nr, end=' ')
elif nr<60:
print(nr, end=' ')
elif nr<70:
print(nr, end=' ')
elif nr<80:
print(nr, end=' ')
elif nr<90:
print(nr, end=' ')
elif nr<100:
print(nr, end=' ')
Thanks in advance
