large array in a single line

[karthik167 at gmail.com]

I would like to have a txt file of single line with
[1 2 3 .........100]

I try something like
q=arange(100)
fl=file('tmp.ext','w')
fl.writelines(str(q))
fl.close()

Unfortunately my output is

[ 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]

ie there is automatic split in line after 76 characters. How do I
avoid it? Thanks.
