Read the guideline before starting.

Create an app create_file.py that takes directory path, file name, file content from the terminal and creates file. There should be flags -d or -f:

• If only -d flag passed, means all items after this flag are parts of the path.

python create_file.py -d dir1 dir2 - creates directory dir1/dir2 inside current directory.

• If only -f flag passed, means first item is the file name.

python create_file.py -f file.txt

After pressing Enter it creates file file.txt and then terminal should ask you to input content lines until you input "stop":

Enter content line: Line1 content
Enter content line: Line2 content
Enter content line: Line3 content
Enter content line: stop

This creates file file.txt inside current directory with content:

2022-02-01 14:41:10
1 Line1 content
2 Line2 content
3 Line3 content

App should add current timestamp at the top and number lines. If file.txt already exists it should add content below:

python create_file.py -f file.txt

Enter content line: Another line1 content
Enter content line: Another line2 content
Enter content line: Another line3 content
Enter content line: stop

2022-02-01 14:41:10
1 Line1 content
2 Line2 content
3 Line3 content

2022-02-01 14:46:01
1 Another line1 content
2 Another line2 content
3 Another line3 content

• If both -d and -f flags passed, app creates directory and file with content inside this directory.

python create_file.py -d dir1 dir2 -f file.txt

Enter content line: Line1 content
Enter content line: Line2 content
Enter content line: Line3 content
Enter content line: stop

Creates directory dir1/dir2 inside current directory and creates file file.txt inside that directory with content:

dir1/dir2/file.txt:

2022-02-01 14:46:01
1 Line1 content
2 Line2 content
3 Line3 content

It would be relevant to use:

• sys.argv to read arguments from the terminal
• os.makedirs to create directories
• .strftime() method for datetime.now() to make timestamp more beautiful.
