Is there a way to use random.choice?

Is there a way to use random.choice in a manner that it will select a random letter from a str a random number of times?

    ```def drugname(v,c): 
          con = random.choice(c)
       if con == "q":
          vowel = "u"
       else:
          vowel = random.choice(v)
       return con + vowel
    ```

I am trying to figure out how to get random.choice(c) and random.choice(v) to get selected a random number of times.
