Replace n with br

Question

I m parsing text from file with Python  I have to replace all newlines   n  with  cause this text will build html-content  For example  here is some line from file    title n    Now I do   thatLine replace   n     lt br   gt    print thatLine   And I still see the text with newline after it

The Problem is When you denote   n  in the replace   call     n  is treated as a String length 4  made out of     n   To get rid of this  use ascii notation  http   www asciitable com   example   newLine   chr 10  thatLine thatLine replace newLine     lt br   gt      print thatLine   python3  print thatLine  python2

Just for kicks  you could also do  mytext     lt br   gt   join mytext split   n      to replace all newlines in a string with  lt br   gt

To handle many newline delimiters  including character combinations like  r n  use splitlines  see this related post  use the following     lt br   gt   join thatLine splitlines

thatLine   thatLine replace   n     lt br   gt     str replace   returns a copy of the string  it doesn t modify the string you pass in

I know this is an old thread but I tried the suggested answers and unfortunately simply replacing line breaks with  lt br   gt  didn t do what I needed it to  It simply rendered them literally as text   One solution would have been to disable autoescape like this     autoescape false      mystring      endautoescape    and this works fine but this is no good if you have user-provided content  So this was also not a solution for me   So this is what I used   In Python   newvar   mystring split   n     And then  passing newvar into my Jinja template      for line in newvar         lt br   gt    line       endfor

You could also have problems if the string has  lt    gt  or  amp  chars in it  etc  Pass it to cgi escape   to deal with those    http   docs python org library cgi html highlight cgi cgi escape

thatLine   thatLine replace   n     lt br   gt      Strings in Python are immutable  You might need to recreate it with the assignment operator
