Python Coding Challenge - Question with Answer (ID -080726)

 

Explanation:

🔹 Line 1: Import Path

from pathlib import Path

Path is imported from Python's modern pathlib module.

It provides an object-oriented way to work with file and folder paths instead of using string operations.

🔹 Line 2: Create a Path Object

Path("a/b/c")

Python creates a Path object representing the path:

a/b/c

Directory structure:

a

│

└── b

     │

     └── c

🔹 Line 3: Access the parents Property

Path("a/b/c").parents

The .parents property returns all parent directories of the path.

It behaves like a sequence (similar to a tuple), where:

Index    Parent

----------------

0        a/b

1        a

So internally:

Path("a/b/c").parents

is approximately:

(

    Path("a/b"),

    Path("a")

)

🔹 Visual Representation of parents

Current path:

a

│

└── b

     │

     └── c

Parents are:

parents[0]

a

│

└── b

and

parents[1]

a

🔹 Line 4: Access Index 1

Path("a/b/c").parents[1]

Python selects the parent at index 1.

From the parent list:

Index 0 → a/b

Index 1 → a

Therefore:

Path("a/b/c").parents[1]

returns:

Path("a")

🔹 Line 5: Print the Result

print(Path("a/b/c").parents[1])

Python prints the path:

a

Output:

a
