• for i = 0 to 9
  print("Hi")
• for i = 0 to 10

  print("Hi")
• for i  (0 to 9)
  print("Hi")

password = ""
while password != "CdRtp45@":
password = input("Password?")
HINT: Python code doesn't require and end while

• password = ""
  while password != "CdRtp45@"
  password = input("Password?")
  endwhile
• password = ""
  while password != "CdRtp45@"
  password = input("Password?")

To find the length of a string the Python code is:
len(string_name)
What is the OCR Pseudocode?

• string_name.length()
• length.string_name
• length(string_name)

A comment in Python is shown by using the # symbol e.g.
