Best answer
Usually,we draw manual Control Flow Graph usingpen and paper by analyzing the control flow of the program. CFG helps us finding independent paths ( Cyclomatic Complexity ),which leads to the number of test cases required to test the program. We can automate the CFG task using a Python library called pycfg.

What are the characteristics of a control flow graph?
It begins with a labelled operation and ends with a branch, jump, or predicated operation. A control-flow graph ( cfg) models the flow of control between the basic blocks in a program. A cfg is a directed graph, G = ( N, E ). Each node n 鈭?N corresponds to a basic block.

How do you write a flow graph with multiple statements?
Control flow graphs are usually not written with one statement per node, but divide the code into basic blocks that combine multiple statements. A basic block starts with a jump target and ends with a jump to another block.
What is the difficulty level of control flow graph (CFG)?
