Exam PCAP topic 1 question 59 discussion

A. import a.b.c should be placed before that line. This option is correct. If a.b.c.f() is a function call and the module or subpackage a.b.c is not yet imported, you should import it before using it to avoid a NameError. Placing import a.b.c before this line ensures that the module or subpackage is available for use. B. f() is located in subpackage c of subpackage b of package a. This option is correct. The notation a.b.c.f() implies that the function f() is part of the module or subpackage c within the subpackage b within the package a. C. The line is incorrect. This option is incorrect. There's no syntax error in the line x = a.b.c.f(). The line assigns the result of the function call a.b.c.f() to the variable x, assuming that the module or subpackage a.b.c is correctly defined and imported. D. The function being invoked is called a.b.c.f(). This option is incorrect. The function being invoked is f(), and it is located in the module or subpackage a.b.c. The notation a.b.c.f() denotes the hierarchy of the module or subpackage structure, but the actual function name is f().

A and D

I believe the correct answer is A and D. import a.b.c #imports module c from subpackage b of package a x = a.b.c.f() # invokes the function/class constructor f defined in module c, using its fully qualified name

Why is D not correct?

A and B Two things you can deduce from the line of code are: a is an object that has an attribute b. b is an object that has an attribute c, and c has a method f that is being called. The line of code creates a variable x and assigns to it the result of calling the method f on the attribute c of the attribute b of the object a. This implies that a is an object that has an attribute b, which is itself an object that has an attribute c, which is an object that has a method f.

In the first time i was thinking that A and B but if it's B it should be like this : from module C of subpackage B of package A

It is A and B

It is A and B

A. import a.b.c should be placed before that line Most Voted B. f () is located in subpackage c of subpackage b of package a

I think A and B should be the correct answer.

AB are the correct answers

It should be a and b

A and B is correct

i think A and B is correct

A and B is correct.

(a = package b = subpackage c = module f() = function)

A. import a.b.c should be placed before that line B. f () is located in subpackage c of subpackage b of package a
