Re: A random word from one of two lists
Try this:
>>> animal = ['koala', 'kangaroo']
>>> fruit = ['banana', 'apple']
>>> words = {'animals': animal, 'fruits': fruit}
>>> kinds = tuple(words.keys())
>>> kind = random.choice(kinds)
>>> kind
'animals'
>>> word = random.choice(words[kind])
>>> word
'koala'

This is fine.

This probably isn't what you intend. Print out kinds:
print(repr(kinds))
>words = {'animals': animal, 'fruits': fruit}
I suspect you want, after this line:
kinds = list(words.keys())
which gets you a list of the dictionary keys. Print that, too, to see
the difference.
>kind = random.choice(kinds)
>print(kind)
When the earlier stuff works, this should be a string.
>word = random.choice(kind)
This picks a random character from the string. Probably not what you
want. You want to pick from the list of animals or fruits. Since you
(will) have the word "animals" or "fruits" in "kind", how do you
reference the appropriate list?

random.choice doesn't return 'a variable' but an object. Which is the
same object that one of the variables that you used.
IF you wanted to use words, then you could have made kinds = {'animals',
'fruits'} and then looked up the list in words, but that is really just
more work (unless you want to know which list it came from)
Note that 'animals' isn't a variable, but a string value.

A random word from one of two lists
I have two lists *animal* and *fruit* and I try to get a random variable
animal or fruit and then random word from that list.
I thought that dictionary(*words*) could help me but no succes, the only way
I've
done partially what was with list *kinds* and by using two times
random.choice. However print(kind) return me a list not a variable:
animal or fruit so now I'm kinda confuse if I can achieve that.
import random
animal = ['koala', 'kangaroo']
fruit = ['banana', 'apple']
kinds = [animal,fruit]
words = {'animals': animal, 'fruits': fruit}
kind = random.choice(kinds)
print(kind)
word = random.choice(kind)
print(word)
#output:
['kolala', 'kangaroo']
kangaroo
