Read the first 7 Using `sep=` and `end=` in `print()` flashcards as text

  1. What is the output of `print('Python', 3, sep='.')`?

    Answer: Python.3

    sep='.' is placed between the string 'Python' and the integer 3 after it is converted to its string representation.

  2. Which of the following will print three items on the same line separated by tabs?

    Answer: Both A and C

    Both using `sep='\t'` and embedding `\t` directly in one string produce tab-separated output on one line.

  3. What is the result of: ``` print('A', end='B') print('C') ```

    Answer: ABC

    The first print ends with 'B' instead of '\n', so 'C' from the second print immediately follows, producing 'ABC' on one line.

  4. What is the default value of the `sep=` parameter in Python's `print()` function?

    Answer: A single space ' '

    The default separator is a single space, which is why `print('a', 'b')` outputs `a b`.

  5. What does the following print? ``` print(*[1, 2, 3], sep='-') ```

    Answer: 1-2-3

    The `*` unpacks the list into three separate arguments, and `sep='-'` places a hyphen between each of them.

  6. Which statement correctly describes `end=` in `print()`?

    Answer: It sets the string appended after all arguments are printed

    `end=` controls the string that is appended after all positional arguments have been printed, defaulting to '\n'.

  7. What is the output of: ``` print('1', '2', sep='0', end='0') ```

    Answer: 1020

    sep='0' places a '0' between '1' and '2' giving '102', then end='0' appends another '0' giving '1020'.
