How to divide two columns of type `pandas.core.series.Series`?

Question

I need to divide two series element wise. The elements are of type float.

A = [10,20,30]
B = [2,5,5]
result = A/B

I expect

result = [5,4,6]

but get

result = [NaN, NaN, NaN]

Answer 1

This just works with pandas Series as expected:

In [3]: import pandas as pd

In [4]: A = pd.Series([10,20,30])

In [5]: B = pd.Series([2,5,5])

In [6]: A/B
Out[6]:
0    5
1    4
2    6
dtype: float64
