[Tutor] creating a tab delimited filename

[jrlen balane]

so for example, i have 5 arrays, i can do this (is this correct):

data1[1,2,3,4,5 (and so on)]
data2[1,2,3,4,5 (and so on)]
data3[1,2,3,4,5 (and so on)]
data4[1,2,3,4,5 (and so on)]
data5[1,2,3,4,5 (and so on)]
datas = [data1, data2, data3, data4, data5]

for data in datas:
    lines.append('\t'.join(data) + '\n')        
    
=================================
(supposed to be output)
1     2    3    4     5  ...
1     2    3    4     5  ...
1     2    3    4     5  ...
...

(but i want this output)
1    1    1     1    1
2    2    2     2    2
3    3    3     3    3
...   ...  ...   ...    ...
=================================

output_file = file('c:/output.txt', 'w')
output_file.writelines(lines)
output_file.close()
=================================

how am i going to change the filename automaticaly?
for example:
        #every 5 minutes, i am going to create a file based on the data above
 for i in range(100)      
        output_file = file('c:/output' +.join(i) +'.txt', 'w')    
#guess this won't work
        output_file.writelines(lines)
        output_file.close()
