<div>Thank you all for your help. </div>
<div>1) I need to list words with uppercase first, then those with lower case; I used istitle() and isupper (don't know the method for mixed case yet)</div>
<div>2) Steve, it's a compliment that you though I'd undersand your code, but I only know conditional statements, started on lists, not functions yet. nand is still Greek to me right now. <br>3) If someone input "Thank you my FOLKS, i want the output to print words with upper case first:</div>
<div> </div>
<div>Thank</div>
<div>FOLKS</div>
<div>you</div>
<div>my</div>
<div> </div>
<div>3) Can someone help me make my code work in a very simple way. I am still learning, but watch this space colleagues; I may be helping you guys in a few months ;)</div>

<div>Thanks to all who took their time to help.</div>

<div>My initial code:<br> <br>s=input("Write a sentence: ")<br>list=s.strip().split()<br>for word in list:<br> list2 = (word.isupper() or word.istitle())<br> print (word)<br>else print (word)</div>

If that is the case, then I would recommend opening the pdf in binary mode and figuring out how to deflate the correct objects before doing any searching.
