memory-graph 0.1.1

Draw a graph of your data to see the structure of its references.

Graph your Memory

Want to draw a graph of your data in Python to better understand its structure or the Python memory model in general?

Just call "memory_graph.show(your_data)", an example:

import memory_graph

data = [ (1, 2), [3, 4], {5:'five', 6:'six'} ]
memory_graph.show( data )

This shows the graph with the starting point of your 'data' drawn using thick lines, the program blocks until the key is pressed.

If show() doesn't work well on your system (the PDF viewer integration is platform specific) use render() to output the graph in the format of your choosing. Use block=False to turn off blocking.

memory_graph.render( data, "my_graph.png", block=False)

Larger Example

This larger example shows objects that share a class (static) variable and also shows a recursive reference.

import memory_graph

my_list = [10, 20, 30]

class My_Class:
    my_class_var = 1000 # class variable: shared by different objects
    
    def __init__(self):
        self.var1 = "foo"
        self.var2 = "bar"

obj1 = My_Class()
obj2 = My_Class()

data=[my_list, my_list, obj1, obj2]

my_list.append(data) # recursive reference

memory_graph.show( data )
