How to use less memory to store data in dict python
<p>I have some data which is about 1.5GB. Now I want to store those information into a big dict in python. However, it costs much bigger than 1.5GB, maybe 10 times. The machine doesn't have so much memory. Is there any way to use less memory to put those data into a dict structure? The key and value are all integer.</p>

<p>Best Regards,</p>
