I don t feel that anyone addressed the     part of your question  When you read each line into your variable  because there were multiple lines before you replaced the  n with    you ended up creating a list  If you have a variable of x and print it out just by  x   or print x   or str x   You will see the entire list with the brackets  If you call each element of the  array of sorts   x 0  then it omits the brackets  If you use the str   function you will see just the data and not the    either  str x 0

I have fiddled around with this for a while and have prefer to use use read in combination with rstrip  Without rstrip  quot  n quot    Python adds a newline to the end of the string  which in most cases is not very useful   with open  quot myfile txt quot   as f      file content   f read   rstrip  quot  n quot       print file content

To remove line breaks using Python you can use replace function of a string   This example removes all 3 types of line breaks   my string   open  lala json   read   print my string   my string   my string replace   r      replace   n      print my string    Example file is        lala    lulu      foo    bar      You can try it using this replay scenario   https   repl it repls AnnualJointHardware

This works  Change your file to   LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE   Then   file   open  file txt   line   file read   words   line split     This creates a list named words that equals     LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN    GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE     That got rid of the   n   To answer the part about the brackets getting in your way  just do this   for word in words    Assuming words is the list above     print word   Prints each word in file on a different line   Or   print words 0         words 1    Note that the     symbol indicates no spaces  The comma not in parentheses indicates a space   This returns   LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN  GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE

I m surprised nobody mentioned splitlines   yet  with open   quot data txt quot    quot r quot   as myfile      data   myfile read   splitlines    Variable data is now a list that looks like this when printed    LLKKKKKKKKMMMMMMMMNNNNNNNNNNNNN    GGGGGGGGGHHHHHHHHHHHHHHHHHHHHEEEEEEEE    Note there are no newlines   n   At that point  it sounds like you want to print back the lines to console  which you can achieve with a for loop  for line in data      print line
