PCAP Strings Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  s = ('Line1\n' 'Line2')

  Why this is correct

  This is correct because Python implicitly concatenates adjacent string literals at compile time. The expression ('Line1\n' 'Line2') produces the single string 'Line1\nLine2', where \n is a single escape character representing a line break. When printed, the result appears on two lines, so it is a valid multiline string. The parentheses are not required but help break long lines for readability.

• ✓

  s = """Line1 Line2"""

  Why this is correct

  This is correct because triple double quotes, like triple single quotes, let a string span multiple physical source lines while preserving the embedded line breaks exactly as typed. The resulting string contains a newline character at the end of the first line, so it behaves as a genuine multiline string. This syntax is the standard choice for docstrings and is also convenient for writing SQL or long formatted text blocks in code.

• ✓

  s = '''Line1 Line2'''

  Why this is correct

  This is correct because triple single quotes allow a string literal to contain literal newline characters, meaning the physical line break between Line1 and Line2 is preserved as part of the string value. It is equivalent to writing 'Line1\nLine2' but is more readable when the string is long. Additionally, triple single quotes permit embedded single quotes without escaping, giving it flexibility for multiline text.

• ✗

  s = "Line1\ Line2"

  Why it's wrong here

  This is incorrect because the backslash at the end of the first line is a line-continuation escape, not a newline-inserting character. It tells Python to ignore the physical line boundary and continue parsing the same logical string literal on the next line, so the resulting value is 'Line1Line2'—a single-line string with no newline. Although the source code occupies two physical lines, the string itself contains no line break, so it is not a multiline string.

• ✗

  s = 'Line1 Line2'

  Why it's wrong here

  This is invalid because a single-quoted string literal cannot span multiple physical lines in Python; the quote after Line1 closes the string, and Line2 is parsed as a separate, unexpected token, causing a SyntaxError. Raw newlines inside a standard string literal are forbidden—they must be escaped as \n or the string must use triple quotes. Thus this source code does not compile.
