Question

string drive_input is read from input. string some_str contains special characters. modify the string literal assigned to some_str by adding a backslash (\\) to the special characters so the program outputs drive_input followed by :\\\documents\\\personal.
ex: if the input is d, then the output is:
d:\\\documents\\\personal
1 drive_input = input()
2
3 # modify the string literal below
4 some_str = drive_input + \\personal\
5
6 print(drive_input, end=\\)
7 print(some_str)

Explanation:

Step1: Fix path escape sequences

We need to escape each backslash in the path by adding an extra backslash, and correct the path to match the required output :\Documents\Personal.

Step2: Update the string literal

Replace the incorrect "\personal" with the properly escaped path string, and remove the redundant drive_input concatenation (since we already print drive_input separately).
<Expression>
some_str = ":\\\Documents\\\Personal"
</Expression>

Step3: Verify output flow

The first print outputs the drive letter, the second print outputs the escaped path, combining to match the required format.

Answer:

The corrected line 4 is:

some_str = ":\\\\Documents\\\\Personal"

When input is D, the program will output:

D:\\Documents\\Personal
