    <p>I'm writing an application for making ringtones for the iPhone. It's just for fun. Here's what I've done till now. (Mind you, i'm a beginner in Python !) So I open my mp3 file in binary mode. read the whole file. Convert it into a list. Use list slicing to split the file. Save this new split into a new mp3 file. This works fine. I however want to the ringtones to have a max of 30 seconds play time and I want the user to choose what portion of the file he wants as the ringtone. Can anyone guide me in the right direction ? Thanks</p> <p>Here's my code till now :</p> <pre><code>f = open("Bruno Mars - Locked Out Of Heaven [OFFICIAL VIDEO].mp3", 'rb').read() mp3 = list(f) fo = open("newFile.mp3", "wb") print(mp3[0:1300000]) fo.write(bytes(mp3[0:1300000])) </code></pre> <p>Here's what I got after some coding:</p> <pre><code>import os f = open("Bruno Mars - Locked Out Of Heaven [OFFICIAL VIDEO].mp3", 'rb').read() fileSize = os.path.getsize("Bruno Mars - Locked Out Of Heaven [OFFICIAL VIDEO].mp3") print("Size of the whole file",fileSize) mp3 = list(f) bitRate = int(input("Enter the bit rate of your file")) size_mbps = bitRate*(15/2048) print("MB per minute :",size_mbps) second_size = int((size_mbps/60)*(10**6)) print("Size of each second :",second_size) start_length = int(input("Enter the start time (in seconds)")) end_length = int(input("Enter the end time (in seconds)")) start_size = int(second_size*start_length) end_size = int(second_size*end_length) fo = open("newFile.mp3", "wb") fo.write(bytes(mp3[start_size:end_size])) </code></pre> <p>It works fine but I need to tweak it a little more. Any input on this code ?</p>

    1. COWe need more info. What library are you using? (or have written a custom one (probably in c, c++)? Also, it will be better if you post some relevant code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
