Exam PCEP-30-02 topic 3 question 173 discussion

It is A --> erroneous. if it is '\\' you have len(x) = 1 if it is '\\\' you have an error if it is '\\\\' you have len(x) = 2

The code x = '\\\' is not erroneous. This is a valid Python string assignment. In Python, the backslash (\) is an escape character. Here's how it works in this case: The first backslash escapes the second backslash, resulting in a single backslash character. The third backslash is not followed by any special character, so it remains as a backslash. Therefore, the string x actually contains two backslashes: '\\'. So, the length of the string x is 2. Thus, the correct answer is: B. 2
