Which is wrong with the Python module time introduction method?

Question

Options

• Aimport time
• Bfrom time import *
• Cimport time as t
• Dfrom time

• A
  3% (1)
• B
  17% (5)
• C
  7% (2)
• D
  72% (21)

Explanation

Option D, from time, is syntactically incomplete and will raise a SyntaxError in Python. The from keyword must always be followed by a module name and then import with at least one name to import, such as from time import sleep. Options A, B, and C are all valid import forms: import time loads the module under its own name, from time import * brings all public names into the current namespace, and import time as t loads the module with an alias. A useful way to remember this is that from never stands alone -- it always needs a partner import clause to complete the statement, just as "from the store" is an incomplete sentence without telling what you brought back.
