Answer 1

don't have to use regular expression (for your sample string)

>>> s
'this is a paragraph with<[1> in between and then there are cases ... where the<[99> number ranges from 1-100. \nand there are many other lines in the txt files\nwith<[3> such tags \n'

>>> for w in s.split(">"):
...   if "<" in w:
...      print w.split("<")[0]
...
this is a paragraph with
 in between
 and then there are cases ... where the
 number ranges from 1-100
.
and there are many other lines in the txt files
with
 such tags
