Python loop to write across columns in CSV
for i in range(0, len(data)-lg):
                    writer.writerow([data[i][0], data[i][1], data[i][2],...])

for i in range(0, len(data)-lg):
                for j in range(0, lg+6):
                    writer.writerow([data[i][j]])

num_cols = lg + 6
for row in data:
    writer.writerow(row[:num_cols])

writer.writerows(data)

for row in data:
    writer.writerow(row)

for x in data:
    writer.writerow(x)
