Python Programming: Empowering Your Code with the Join Method

What is the output of the following Python code snippet?

names = ['Python', 'C++', 'Java']

''.join(names)

Answer:

The correct output is option 3: 'PythonC++Java'.

In the given code snippet, we have a list named 'names' containing three strings: 'Python', 'C++', and 'Java'. The join() method is called on the empty string ''.join(names), where 'names' is passed as an argument. The join() method concatenates all the elements in the 'names' list using the empty string as a separator.

The output of the code is a single string where all the elements in the 'names' list are joined together without any spaces or separators between them. Therefore, the correct output is 'PythonC++Java'.

Let's analyze the other options:

  1. [Python C++ Java]: This option is incorrect because the join() method does not add spaces between the elements of the list.
  2. 'Python m{C}++ \) Java': This option seems to have typographical errors and does not represent the actual output of the code.
  3. [PythonC++Java]: This option is incorrect because the output of the join() method is a string, not a list.
  4. None of them: This option is incorrect because the correct answer is option 3, 'PythonC++Java'.
