A very common pattern is an if statement directly following an else:

if len(password) < 8:
  print("Password too short")
else:
  if len(password) >= 64:
    print("Password too long")

The second if statement checks if the password exceeds the maximum length of 64. This causes an unnecessary double indentation in the code. A cleaner way is to use elif:

if len(password) < 8:
  print("Password too short")
elif len(password) >= 64:
  print("Password too long")
else:
  print("New password confirmed")
