How can I get every Token (word) and PreviousToken(Previous word) From multube files and frequency of each two word

my code is trying to get all single word and double word (every Token (word) and PreviousToken(Previous word)) from multube files and get frequency of both. it can get for single word but double word give error

line 50, in most_frequant_word
word1+= ' ' + word_list[ix+1]

button1 = tk.Button(root, text='Brows', command=most_frequant_word)
button1.pack(pady=5)
text1.focus()
root.mainloop()

the code subose to do
For example if the text file content is
"Every man has a price. Every woman has a price."

First Token(word) is "Every" PreviousToken(Previous word) is none(no previos)
Second Token(word) is "man" PreviousToken(Previous word) is "Every"
Third Token(word) is "has" PreviousToken(Previous word) is "man"
Forth Token(word) is "a" PreviousToken(Previous word) is "has"
Fifth Token(word) is "price" PreviousToken(Previous word) is "a"

Sixth Token(word) is "Every" PreviousToken(Previous word) is none(no previos)
Seventh Token(word) is "man" PreviousToken(Previous word) is "Every"
Eighth Token(word) is "has" PreviousToken(Previous word) is "man"
Ninth Token(word) is "a" PreviousToken(Previous word) is "has"
Tenth Token(word) is "price" PreviousToken(Previous word) is "a"


Frequency of "has a" is 2 (repeated two times first and second sentence)
Frequency of " a price" is 2 (repeated two times first and second sentence)
Frequency of "Every man" is 1 (occur one time only)
Frequency of "man has" is 1 (occur one time only)
Frequency of "Every woman" is 1 (occur one time only)
Frequency of "woman has" is 1 (occur one time only)

please I need help

First, please only post one thread per question. This should probably have gone in your other thread. Your error occurs because when you get to the last element of the list, using ix+1 means that you're outside the list, thus giving you an error.

ok
but
how can I solve it?

[jlm699]

if ix == len(my_list - 1):
    break

[Laharl]

if ix == len(my_list - 1):
    break

Surely you mean:

if ix == len(my_list)-1:
    break

[jlm699]

Oh yeah, absolutely. Thanks for the catch, I think I was typing that as fast as I can whilst working...
