[FIXED] Unable to write index into CSV file

Issue

I am trying to write the index values in a csv file but I am getting error.

code used for writing into csv

test = df.sort_values(['sqdist'], ascending=[False])
for i in range(len(test)):
 print(test.index[i])

The above code gives me output like this. These are the index values and I am trying to write this in a CSV using the below code.

7163
4332
3319
1213
1212
6984
4331
4362
6393
515

Trying to write the above output into a csv file exactly like how i see above.


    
with open ("scores.txt",'w') as f1:
        writer = csv.writer(f1, lineterminator='\n', )
        for i in range(len(test)):
            writer.writerow(test.index[i])
    
    print("Saved the scores in the text file score.txt")


Error:

---------------------------------------------------------------------------
Error                                     Traceback (most recent call last)
<ipython-input-26-748f3db1997a> in <module>()
     94         writer = csv.writer(f1, lineterminator='\n', )
     95         for i in range(len(test)):
---> 96             writer.writerow(test.index[i])
     97 print("Saved the scores in the text file ranking.txt")
     98 

Error: iterable expected, not numpy.int64

Solution

with open ("/scores.txt",'w') as f1:
        writer = csv.writer(f1, delimiter='\t', lineterminator='\n', )
        for i in test:
            writer.writerow([i])
    
 print("Saved the scores in the text file scores.txt")

Above is the modified code
