can you tell me whats wrong with my code?

QUESTION:

Write a python program to open the test file provided and write the contents of this file to a new file called XXXXXX$.$txt while adding line numbers to each line in the new file. You will also write your name and section number as the final line of this new file. The program should then output the number of lines in the file with a meaningful message to the user like "The file has XX lines". The number of lines provided to the user doesn't need to include any additional lines you add for your name and section number.

Output a message to the user thanking them from using your program that includes your first and last name.

My code:

Fname $=$ open$(\text{'}$test$\_$python.txt$\text{'},\text{'}$r$\text{'})$

Lname $=$ open$(\text{'}$XXXXXX$.$txt$\text{'},\text{'}$a$\text{'})$

lineCount $=0$

while True:

line $=$ Fname.readline$()$

if len$($line$)==0$:

break

print$($line$,$ end$="")$

Fname.close$()$

myOutput.close$()$

Lname.write$("\{\}$:$".$ format$($lineCount$))$

Lname.write$("$Fname Lname Sec. The file has $\{\}$ lines". format$($lineCount$))$

while True:

line $=$ Lname.readline$()$

if len$($line$)==0$:

break

Fname.close$()$

print$("$Thank you for using my program $-$ Fname Lname"$)$
