How to prepend a text , Write To Beginning Every Line in TXT and end with an extra row

I have a text file as shown below:

this is 1 line
this is 2 line
this is 3 line

I want to convert it into something like below:

\begin{enumerate}
\item this is 1 line
\item this is 2 line
\item this is 3 line
\end{enumerate}

I am using the code below:

prefix = '\\item '

with open('new.txt', 'r') as src:
    with open('dest.txt', 'w') as dest:
       dest.write("\\begin{enumerate}\n")
       for line in src:
           dest.write('%s%s\n' % (prefix, line.rstrip('\n')))

Reference : Python - Write To Beginning and End of Every Line in TXT

But I can't seem to add the last line "\end{enumerate}" correctly. Can someone help please?

Just add this line at the end of your with clause:

prefix = '\\item '

with open('new.txt', 'r') as src:
    with open('dest.txt', 'w') as dest:
       dest.write("\\begin{enumerate}\n")
       for line in src:
           dest.write('%s%s\n' % (prefix, line.rstrip('\n')))
       dest.write("\\end{enumerate}\n")
