I want to Categorize float variable which has letters as its elements.
Elements:

Horse, Camel, Car, Truck, Walk, Bus, Donkey.

I now want to categorize them into 1 for Animal. 0 for Non-animal.

I've tried to create a new variable

Mode_of_transport = 0

​​​​​​replace Mode_of_transport=1 if old_variable=="Horse"|old_variable=="Donkey"

It's giving me "mismatch"

any suggestions?
