<s>[INST] How can I explicitly free memory in Python? I wrote a Python program that acts on a large input file to create a few million objects representing triangles.  The algorithm is:

read an input file
process the file and create a list of triangles, represented by their vertices
output the vertices in the OFF format: a list of vertices followed by a list of triangles.  The triangles are represented by indices into the list of vertices

The requirement of OFF that I print out the complete list of vertices before I print out the triangles means that I have to hold the list of triangles in memory before I write the output to file.  In the meanwhile I'm getting memory errors because of the sizes of the lists.  
What is the best way to tell Python that I no longer need some of the data, and it can be freed?
 [/INST] According to Python Official Documentation, you can force the Garbage Collector to release unreferenced memory with gc.collect()
