Option B is the correct answer:

Python raw string is created by prefixing a string literal with 'r' or 'R'.

Python raw string treats backslash (\) as a literal character.

This is useful when we want to have a string that contains backslash and don't want it to be treated as an escape character.

Answer:

Option 1 'foo\'bar' is the correct answer.

Explanation:

Using a backslash before a single quotation instructs Python to end the string. so when we used "foo'bar" in the print statement, it won't end and the output will be foo'bar.

  • By adding 'r' or 'R' to a string literal in Python, a raw string is formed.
  • Backslash (\) is treated as a literal character in Python raw string.
  • When we want a string with a backslash in it but don't want it to be considered as an escape character
  • In a raw string, it is escaped when a backslash is followed by a quote. The backslash is still present in the outcome.
  • This feature prevents us from producing a raw string of just backslashes.
  • Additionally, a raw string cannot end with an odd number of backslashes.
