[FIXED] How to create a lambda function to return next cell value?

Issue

For example :

Val1	Val2
48	21
156	45
61	54
12	79
64	45

the excepted output is the followwing :

Val1	Val2	Output
48	21	45
156	45	54
61	54	79
12	79	45
64	45

What I did try is the following but it does not work and I am not sure if it is possible to do with lambda. ) )

DF["Output"] = DF.apply(lambda x: x[1].val2, axis=1)

The final goal is to apply thanks to a lambda function the following calculation :

(21/45) (45/54) (54/79) (79/45) ...

Wihtout having to create a new column with the shifted values as suggested in Ynjxsjmh Answer

Solution

Using Series.shift(-1)

DF["Output"] = DF["Val2"].shift(-1)
