Theoretically, when randomization is used, the same word may be printed several consecutive times, or it may be printed repeatedly (for example, 3 times out of 5 attempts the same word may be printed). I know, this is correct, this is right and normal.

I would like to set the same value of a variable to be printed again only after four times, therefore on the fifth attempt. I simply want to set some sort of "block" for each value and this block must last for four print attempts.

For example, in my code, I would like in the a_random variable, if Word A2 is printed, then Word A2 will only be able to print again after four subsequent printing attempts, but I want to print only one random word among the four (and not print four words).

For example, if I print Word A2, the subsequent prints must be 4 random among "Word A1", "Word A3", "Word A4", "Word A5", "Word A6", "Word A7", "Word A8", then on the fifth attempt it will be able to print Word A2 again (but not mandatory, because in addition to Word A2 it will be possible to print any word).

Important: I want to print only one word at a time. I don't want to print four words or more words at a time. The output I would like is only one word.

root.geometry('300x200')def func():a = "Word A1", "Word A2", "Word A3", "Word A4", "Word A5", "Word A6", "Word A7", "Word A8"print("NEW")a_random = print(random.choice(a))print(" ")  return a_randombutton = ttk.Button(root, text='Random', command=func)
button.place(x=10, y=10)root.mainloop()

This uses a list that keeps track of the blacklisted indices and removes those from sampling. The list will not grow larger than four items.

import random
import numpy as npvocab = np.array(["Word A1","Word A2","Word A3","Word A4","Word A5","Word A6","Word A7","Word A8"
])# a list of all indices of the array
indices = np.arange(0, len(vocab))# a list that will store blacklisted indices as long as they are forbidden (4 time steps)
blacklist = []for i in range(10):# only allow values that were not used in the last for stepsrandom_index = random.choice(list(set(indices) - set(blacklist)))# update blacklist for next runblacklist = [random_index] + blacklist  # add new index at the beginningblacklist = blacklist[0:4]  # only keep four values, remove older itemsprint(vocab[random_index])
