python - Remove index column while saving csv in pandas

Question

I'm trying to create a csv with pandas, but when I export the data to csv it gives me an extra column

d = {'one' : pd.Series([1., 2., 3.]),'two' : pd.Series([1., 2., 3., 4.])}
df0_fa = pd.DataFrame(d)
df_csv = df0_fa.to_csv('revenue/data/test.csv',mode = 'w')

Thus, my result is:

 ,one,two
0,1.0,1.0
1,2.0,2.0
2,3.0,3.0
3,4.0,4.0

But, the expected results are:

one,two
1.0,1.0
2.0,2.0
3.0,3.0
4.0,4.0

Answer 1

What you are seeing is the index column. Just set index=False:

df_csv = df0_fa.to_csv('revenue/data/test.csv',mode = 'w', index=False)
