Another way -
Suppose myResult is the dataFrame that contains your data in the form of 1 col and 23 rows
# label your columns by passing a list of names
myResult.columns = ['firstCol']
# fetch the column in this way, which will return you a series
myResult = myResult['firstCol']
print(type(myResult))
In similar fashion, you can get series from Dataframe with multiple columns.
