I'm a beginner so please forgive me for that question. I would like write program which magnifies letters between characters "<" and ">"
For example Input:
<html> randomchars </html>
Output:
<HTML> randomchars </HTML>
How to do that ?
I only wrote this but this magnifies all words.
while True:
inp = input()
if inp == "":
break
elif inp =="<":
inp=inp.upper()
print(inp)
else:
print(inp)
Thanks for help.

Using index() + loop to extract string between two substrings. In this, we get the indices of both the substrings using index(), then a loop is used to iterate within the index to find the required string between them.
Python String upper() Method The upper() method returns a string where all characters are in upper case.
You can extract a substring in the range start <= x < stop with [start:step] . If start is omitted, the range is from the beginning, and if end is omitted, the range is to the end. You can also use negative values. If start > end , no error is raised and an empty character '' is extracted.
What is isupper() in Python. In Python, isupper() is a built-in method used for string handling. This method returns True if all characters in the string are uppercase, otherwise, returns “False”.
Try re.sub;
print re.sub(r"(</?\w+>)", lambda up: up.group(1).upper(), "<tag>input</tag>")
/?\w+ breakdown below, assuming you can see parenthesis () makes the group and we are trying to match between brackets <>;
? will greedily match 0 or 1 repetitions of the preceding RE.
Therefore, /? will match both start and finish tags.\w will match any Unicode word character, including a-z, A-Z, and 0-9.+ will greedily match 1 or more repetitions of the preceding RE.This will match most tags and then you can replace the tag after converting to uppercase inline using the lambda function, up.
