The import pandas as pd 

Res=pd. DataFrame () 
Res/' a '=1 
Res [' b ']=2 
Res. To_csv (r 'test. CSV, index=0) 

The above code, I expect is trying to get a test. The following are the CSV:

A, b

1
2
But the take-home test. The CSV is like this:

A, b

There is no the second row 1 2



Great god answer

Res [' a ']=[1]
