Pandas Dataframe, join two dt when columns are not equal

Question

Assume I have two datatables, identical shape, say N rows and 2 columns. They have same columns names \"One\", \"Two\"

Call first table \"left\", then call second table

Answer 1

Think you need this:

left[left.One.values != right.One.values]

# One   Two
#1  1     2
#3  2     5
