Question
Asked By – Yariv
I tried:
x=pandas.DataFrame(...)
s = x.take([0], axis=1)
And s gets a DataFrame, not a Series.
Now we will see solution for issue: How to get the first column of a pandas DataFrame as a Series?
Answer
>>> import pandas as pd
>>> df = pd.DataFrame({'x' : [1, 2, 3, 4], 'y' : [4, 5, 6, 7]})
>>> df
x y
0 1 4
1 2 5
2 3 6
3 4 7
>>> s = df.ix[:,0]
>>> type(s)
<class 'pandas.core.series.Series'>
>>>

UPDATE
If you’re reading this after June 2017, ix has been deprecated in pandas 0.20.2, so don’t use it. Use loc or iloc instead. See comments and other answers to this question.
