Answer
f = open("hello.txt", "r")
st = " "
while st:
st = f.readlines()
print(st)
f.close()
If the file "hello.txt" was opened in write mode instead of append mode, it would have overwritten the existing content of the file. In write mode ("w"), opening the file truncates its content if it already exists and starts writing from the beginning. Therefore, the previous contents of the file would have been replaced with the new lines provided in the write mode code snippet.
