Reveal correct answer
Correct answer: A
Explanation
Topics: from import
Try it yourself:
- # First execute the following to create the needed file:
- text = '''
- def func():
- print("I am a function, goo goo g'joob!")
- '''
- with open('mod.py', 'w') as f:
- f.write(text)
- from mod import func
- func() # I am a function, goo goo g'joob!
Explanation:
Only the function func() of the module mod gets imported here.
To invoke the function you just need the function name: func()
(There is another question about this topic Q240.)
Q446 (Please refer to this number, if you want to write me about this question.)
A. By using the syntax func(), you can directly invoke the function that has been imported from the module. This is the correct way to call the function after importing it using the specified syntax.
B. The syntax mod::func() is incorrect as the double colon (::) is not a valid operator for calling functions in Python. This syntax is not recognized by Python, and attempting to use it to invoke the function would result in a syntax error.
C. The syntax mod.func() is incorrect in this context because the function has been imported directly as func, not as a method of the mod module. Using this syntax would result in a 'NameError' as the function is not accessed through the module.
D. The syntax mod:func() is incorrect as the colon (:) is not used to call functions in Python. This syntax is not valid for invoking functions, and using it would result in a syntax error.
