Filename: memory_example.py Line # Mem usage Increment Occurrences Line Contents ```这里的“Mem usage”表示内存使用量，“Increment”表示内存增量，“Occurrences”表示该行代码执行的次数，“Line Contents”则是每行代码的内容。通过分析这些信息，你可以深入了解程序中各部分的内存占用情况。◇ 内...
这段代码中,example_function执行时,会自动开启性能剖析 ,并在结束时打印函数内部各部分的耗时统计。 10.2 热函数快速定位 性能剖析的目的是快速识别代码中的热区(hotspot),即耗时最多的地方。结合装饰器使用,可直接定位到具体函数或代码段。 from functools import wraps import cProfile def line_by_line_profile(f...
