Can you help? > Walk through exactly what the computer is doing here. First it prints a, then a newline, then b, then a newline: --begin-- a b --end-- Then your for loop executes (notice LDFile and f are different file objects, so they won't write to the same location). This will print a tab, followed by the i'th element of a, followed by another tab, followed by the i'th element of b. So this: a 1 3 5 6 10 b a t q r s --begin-- [tab] 1 [tab] a [tab] 3 [tab] t [tab] 5 [tab] q [tab] 6 [tab] r [tab] 10 [tab] s [tab]--end-- So the final file will look something like this: a b 1 a 3 t 5 q 6 r 10 s which is obviously not what you want. The following code will do what you want (although there are ways of doing this in less code, this is the most straightforward): f.write('a\t') for element in a: f.write(str(element) + '\t') f.write('\n') f.write('b\t') for element in b: f.write(str(element) + '\t') f.write('\n') HTH, Jason --e89a8f23551f50f6fd04d913ee5b Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

Hello!!!

I have this lists a=3D[1,3,5,6,10], b=3D[a,t,q,r,s] and I need to export it= to a txt file and I can't use csv.

It would help if you showed exactly what you had in your program or in the= Python interpreter. =A0For instance

a =3D [1, 3, 5, 6, 10]
b =3D [a, t, q, r, s]= =A0

won't work, since it interprets the letter= s in the b-list as variables rather than strings. =A0It would need to be

b =3D ['a', 't', 'q', 'r', &= #39;s']

or something equivalent. =A0Assuming y= ou had that part correct:

a 1 3 5 6 10
b a t q r s

--begin-- [tab] =A01 [tab] =A0a [tab] =A0 3 [tab] =A0 t [= tab] =A0 5 [tab] =A0 q [tab] =A0 6 [tab] =A0 r [tab] =A0 10 [tab] =A0 s [ta= b]--end--

So the final file will look something li= ke this:

a
b
=A0 =A0 =A01 =A0 =A0 a =A0 =A0 3 =A0= =A0 t =A0 =A0 5 =A0 =A0 q =A0 =A0 6 =A0 =A0 r =A0 =A0 10 =A0 =A0 s


which is obviously not what you want. =A0T= he following code will do what you want (although there are ways of doing t= his in less code, this is the most straightforward):

f.write('a\t')
for element in a:
=A0 =A0f.write(str(element) + '\t')
f.write('\n= ')
f.write('b\t')
for element in b:
=A0 =A0f.write(str(element) + '\t')
f.write('\n')=
