一般的sys.getsizeof()显示不了复杂的字典。
查看类中的内容
def dump(obj):
for attr in dir(obj):#dir显示类的所有方法
print( obj.%s %r % (attr, getattr(obj, attr)))
这里用递归调用所有对象的getsizeof
def get_size(obj, seenNone):
# From https://goshippo.com/blog/measure-real-size-any-python-object/
# Recursively finds size of objects
size sys.getsizeof(obj)
if seen is None:
seen set()
obj_id id(obj)
if obj_id in seen:
return 0
# Important mark as seen *before* entering recursion to gracefully handle
# self-referential objects
seen.add(obj_id)
if isinstance(obj, dict):
size sum([get_size(v, seen) for v in obj.values()])
size sum([get_size(k, seen) for k in obj.keys()])
elif hasattr(obj, __dict__):
size get_size(obj.__dict__, seen)
elif hasattr(obj, __iter__) and not isinstance(obj, (str, bytes, bytearray)):
size sum([get_size(i, seen) for i in obj])
return size
希望本文所述对大家Python程序设计有所帮助。
