Check any element of an array inside a list

Question

Assume I got an array, created by a pandas dataframe with array = df.index.values and looks like following:

array
array(['A', 'B', 'C', 'D',
       'E', 'F', 'G', 'H'], dtype=object)

and I got a python list looks like following:

list = ['AB', 'AC', 'AD', 'AE', 'AF', 'AG', 'A']

Looking for a function, which does following:

If any element of array is also in list, give me True. If not give me False.

PS: I am not looking for finding the element. Just want to know if such element exist.

any([a in list for a in array]) Is that what you are looking for? — E.Serra, Aug 31 '18 at 10:22
It is not the same question @jezrael. There were 2 list compared. I am looking for an pandas function which iterates over its array items and checks if that element is inside a list. — oakca, Aug 31 '18 at 10:33
@Icedkk - It not exist in pandas. Need all solutions from dupes. Or can you expalin more? — jezrael, Aug 31 '18 at 10:34
@Icedkk - I am a bit confused `Array = array(['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'], dtype=object)` is `Series`? or numpy array? What return in real data `print (type(Array))` ? — jezrael, Aug 31 '18 at 10:42
array is pandas `df.index.values` and checked again it is `numpy.ndarray` and it returns a normal list with print. — oakca, Aug 31 '18 at 10:45
But also working all solutions from dupes, becasue array should be coerced to list — jezrael, Aug 31 '18 at 10:48
hmmm, can you add to question `array` is `df.index.values` ? — jezrael, Aug 31 '18 at 10:51

Pandas solution with Index.isin and Index.any:

df.index.isin(List).any()
