Find the output of the following Python Code:
Assume note.txt initially contains: ABCDEFGHIJ

def UpdateNotes():
with open("note.txt", "r+") as F:
F.seek(3)
F.write("123")
F.seek(0)
Content = F.read()
F.seek(5)
Char = F.read(1)
print(Content)
print(len(Content))
print(Char)
print(Content.startswith("ABC"))

UpdateNotes()

Show answer & explanation
  • File is opened in "r+" mode ⇒ allows reading and writing without deleting existing content.

  • Initial content: "ABCDEFGHIJ"

  • F.seek(3) ⇒ pointer moves to index 3 (character 'D')

  • F.write("123") ⇒ replaces 'D','E','F' ⇒ new content: "ABC123GHIJ"

  • F.seek(0) and read()Content = "ABC123GHIJ"

  • len(Content)10

  • F.seek(5) ⇒ pointer at index 5 ⇒ character '3'Char = '3'

  • Content.startswith("ABC")True

  • Final Output:

    ABC123GHIJ  
    10  
    3  
    True
