Task

"""


The function accepts as parameters:

1. Path to File (String).
Just as in the previous exercise, the file represents a playlist of songs and has a fixed format built from the song name, performer name (singer / band), and song length, separated by semicolon (;) without spaces.

An example of an input file called songs. Text:

Todo Boom; Static and Ben El Tabori; 5:13;
I must feel; The black peas eyes; 4: 05;
Instrumental; Unknown; 4:15;
heaven; Coldplay; 4:23;
Where is the love ?; Black-eyed peas; 4:13;

2. A string representing the name of a new song.

My_mp4_playlist function:

1. The function writes to the file the string representing a new song name (new_song) instead of the key song name in the third line of the file (If the file contains less than your own lines, write to a blank line file so that the song name is written in the third line).
2. The function prints the contents of the file after the change has been made.

An example of running the my_mp4_playlist function on the songs.txt file

>>> my_mp4_playlist (r "c: \ my_files \ songs.txt", "Python Love Story")
Todo Boom; Static and Ben El Tabori; 5:13;
I must feel; The black peas eyes; 4: 05;
Python love story; Unknown; 4:15;
heaven; Coldplay; 4:23;
Where is the love ?; Black-eyed peas; 4:13;




Content of the songs.txt file after running the my_mp4_playlist function

Todo Boom; Static and Ben El Tabori; 5:13;
I must feel; The black peas eyes; 4: 05;
Python love story; Unknown; 4:15;
heaven; Coldplay; 4:23;
Where is the love ?; Black-eyed peas; 4:13;

def main():	
    <call the function>

if __name__ == "__main__":
    main()

your code will replace the song name in the third line, but what if we have the same song name for the 3 and 4 line? both will be changed
for example:

Todo Boom; Static and Ben El Tabori; 5:13;
I must feel; The black peas eyes; 4: 05;
Instrumental; Unknown; 4:15;
Instrumental; Coldplay; 4:23;
Where is the love ?; Black-eyed peas; 4:13;

after the function:

Todo Boom; Static and Ben El Tabori; 5:13;
I must feel; The black peas eyes; 4: 05;
Python love story; Unknown; 4:15;
Python love story; Coldplay; 4:23;
Where is the love ?; Black-eyed peas; 4:13;
