Is there a more pythonic / efficient way of finding and replacing text between two words in a string?

string = "<start>processing<end>"

# Create start and stop indexes to get text between two words
start = string.find("<start>") + len("<start>")
end = string.find("<end>")
substrig = string[start:end]

# Update the word
string = string.replace(substrig, "Shipped")

print(string)
# Prints <start>Shipped<end>

yes. It's called [regular expressions](https://docs.python.org/3/library/re.html) – Tomerikoo Aug 26 '20 at 17:52
alternative option: use an existing formatting or templating engine, if you can (can be as simple as string.format, all the way to the complexity of jinja2) – njzk2 Aug 26 '20 at 17:52
Use regular expressions. – Pranav Hosangadi Aug 26 '20 at 17:52
