You could do something like this, but for sure there are better solutions:

text ="hello bye"
text_out = []
times_to_duplicate = 3
for word in text.split(" "):
    for i in range(times_to_duplicate + 1):
        text_out.append(word)

" ".join(text_out)

Or as list comprehention, as @Sushanth states:

"".join(f"{x} " * 3 for x in "hello bye".split())

I would recommend you, before asking a question to check the grammar and punctuation to improve the quality of your question

``range`` is redundant here, ``"".join(f"{x} " * 3 for x in "hello bye".split())`` – sushanth Aug 02 '20 at 08:16

In python, you can replicate a string by multiplying the string n number of times.

example: this will repeat hello 3 times

>>> 'hello' * 3
'hellohellohello'

If you want a space between that, then you can do it as follows:

>>> 'hello ' * 3
'hello hello hello '

Using this as your base, you can write the code as follows to get the desired result.

txt = 'hello bye'
#now split the word and iterate thru each word by creating a new list
txt1 = [(t+' ')*3 for t in txt.split(' ')]

#you now have a new list txt1 with repeated words
#if you want it as a single string, you need to concatenate that using join

txt2 = ' '.join(txt1)

print (txt2)

do you know how to duplicate several times each word in a text file using python?
