pycallgraph 追溯代码的实现过程

实现过程
第一步：
     1.pip install pycallgraph
第二步：
     1.安装graphviz
            A.macOS brew安装：brew install graphviz
            B.windows https://pythondict.com/go/?url=https://graphviz.gitlab.io/_pages/Download/windows/graphviz-2.38.msi,
      配置环境变量后，然后重启
     2.配置
      

     

第三步：
     1.运行代码就行

from pycallgraph import PyCallGraph
from pycallgraph.output import GraphvizOutput
from pycallgraph import Config
from pycallgraph import GlobbingFilter

def work():
    print(111)


class Banana:

    def eat(self):
        pass


class Person:

    def __init__(self):
        self.no_bananas()

    def no_bananas(self):
        self.bananas = []

    def add_banana(self, banana):
        self.bananas.append(banana)

    def eat_bananas(self):
        [banana.eat() for banana in self.bananas]
        self.no_bananas()


def main():
    graphviz = GraphvizOutput()
    graphviz.output_file = 'basic.png'
    config = Config()
    config.max_depth = 10 # 控制最大追踪深度

    with PyCallGraph(output=graphviz, config=config):
        #work()
        person = Person()
        for a in range(10):
            person.add_banana(Banana())
        person.eat_bananas()


if __name__ == '__main__':
    main()
