Hi
I would like to test whether strings in a numpy S array are in a given list but
I don't manage to do so. Any hint is welcome.
=======================================================
# So here is an example of what I would like to do
# I have a String numpy array:
import numpy as num
Sarray = num.asarray(["test1","test2","tutu","toto"])
Farray = num.arange(len(Sarray))
mylist = ["tutu","hello","why"]
# and I would like to do:
result = num.where(Sarray in mylist, Farray, 0)
=======================================================
===> but of course I get a ValueError since the first test syntax is wrong. I
would like to be able to do:
Sarray in mylist
and get the output:
array([False, False, True, False],dtype=bool)
since only the 3rd string "tutu" of Sarray is in mylist.
Any input is welcome.
cheers
Eric
