Repeat keywords at end of every line

[knob]

Good evening, I would like to read a text file and create an output with the results.
I'm new on python and i'm looking a way to develop this code.
Any suggestion on how to start it ?

• Check all lines, looking for KEYWORD.
  
• Once it finds, copy from pos X to pos Y (fixed position, hard-coded )
  
• Write the copied string at end of every line at pos Z (fixed position, hard-coded)
  
• if KEYWORD is found again on the next line the steps above...
  
• writing everything on the output file.
  

Output:
abcabc abc abvc canc KEYWORD  TOBEREPLIC1    TOBEREPLIC1
asd  alskdlask laks dlkal  lakslkalkas       TOBEREPLIC1
aslddsas laskd laskl  lsklklklk asdda        TOBEREPLIC1
                                             TOBEREPLIC1

You received similar (though I would say not the most polite) feedback last time - we'd love to help you with writing your code, but we typically expect you to make an attempt first, especially since this sounds like homework. Given that you were doing Python nearly a year ago, by your previous post, you should be able to come up with at least a little bit of code, and ask a specific question about exactly what's blocking you from the next step.

your guess is incorrect.. this is not home work...
and please don't feel obligate to contribute with nothing (as you just did).. just don't post nothing...
also.. if you read again.. i'm not asking you code nothing for me... "Any suggestion on how to start it ?"
again... just don't post nothing.. you are doing not more than push away new users from the language...

None of the below is to say you necessarily won't get the answer you're looking for...

Don't be offended, but we put homework-like questions in the Homework section to discourage people from spoiler answers, since the goal of the forum is education, and not getting programs written. I realize you only asked for how to start, not for code, but sometimes people simply give code answers to questions like this, even though we discourage it. As such...

Your post would fall under Homework and No Effort Questions rules. Your post has not shown effort; you could have said "this is what I think..." for example. While we don't want to discourage people new to the language, coding requires continuous effort be put into learning, and I'll point out a big part of coding is getting started, and playing around with the code. You can't expect other people, for simple programs, to tell you how to get started. Specific questions are great, though.

Python has duck-typing and for me this is 'assignment type'.

When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.

I also observe that the description is ambiguous or missing some vital points.

That aside I would recommend break task at hand into smaller subtasks. Something like:

- how to open the file and iterate it row-by-row
- how to determine whether row (string) contains specific substring
- how to copy from position X to position Y
- how to add to the string at specific position, even if it's out of bounds
- how to write to file

All these subtasks are simple enough to solve and combining them all together should give solution.
