Replace Across A File

Write the three lines in draft to draft.txt, then read two words from input: the word to find and the word to put in its place. Read draft.txt into a list with readlines, and write every line to final.txt with the old word swapped for the new one using the string method replace, counting the lines in which the old word occurred (test with in before replacing). Finally read final.txt with f.read(), print it with end="", then print Replaced in <n> line(s). Input: two lines, no prompt.

Expected Output:

the dog sat↵
on the mat↵
a dog naps↵
Replaced in 2 line(s)↵

= newline. The output ends with a newline — print one after the last line.
