Python Coding challenge - Day 747| What is the output of the following Python Code?

 

Code Explanation:

1. Import Required Modules

import glob, os

glob → used to search for files matching a pattern (like *.txt).

os → used for interacting with the operating system (like deleting files).

2. Create First File (a.txt)

with open("a.txt", "w") as f:

    f.write("A")

open("a.txt", "w") → opens file a.txt in write mode. If it doesn’t exist, it will be created.

f.write("A") → writes "A" into the file.

After with block, the file is automatically closed.

Now → a file named a.txt exists with content "A".

3. Create Second File (b.txt)

with open("b.txt", "w") as f:

    f.write("B")

Creates a new file b.txt.

Writes "B" into it.

File is closed automatically after the block.

Now → two files exist: a.txt and b.txt.

4. Count All .txt Files

print(len(glob.glob("*.txt")))

glob.glob("*.txt") → finds all files in the current directory ending with .txt.

At this moment → files are a.txt and b.txt.

So → list contains 2 files.

len(...) → returns the count.

Prints: 2

5. Remove a.txt

os.remove("a.txt")

Deletes the file a.txt from the current directory.

6. Remove b.txt

os.remove("b.txt")

Deletes the file b.txt as well.

Now → no .txt files are left in the directory.

Final Output

2
