Using tuples or Re to replace 5 strings with one

[sem]

Hi, I am trying to simplify a list of fruits in one file, by generalizing them to "fruit". However, I can only using regular tuples and re, replace one by one. Here I would need to replace 4 different words with one, as the example shows below. But it doesn't work. Any ideas?

Thanks

fruit = ("Apple", "Orange", "Banana", "Mandarin")
fruit_trans = {}
fruit_trans = [("fruit")]
trans = string.maketrans("Apple", "Orange", "Banana", "Mandarin")
my_string = my_string.translate(trans)
