Setting many types of values to `category` argument of `warnings.simplefilter()` doesn't get any error

Bug report

Bug description:

Setting Warning to category argument of warnings.filterwarnings() works, then setting the str type value "Hello World" to category argument of warnings.filterwarnings() gets the error message as shown below. *This is an understandable behavior:

import warnings

warnings.resetwarnings()

warnings.filterwarnings(action="ignore", category=Warning)

print(warnings.filters)
# [('ignore', None, <class 'Warning'>, None, 0)]

warnings.filterwarnings(action="ignore", category="Hello World") # Error

print(warnings.filters)

AssertionError: category must be a class

But, setting many types of values to category argument of warnings.simplefilter() doesn't get any error as shown below. *This isn't an understandable behavior:

import warnings

warnings.simplefilter(action="default", category=Warning)         # Understandable
warnings.simplefilter(action="default", category="Hello World") # Not understandable
warnings.simplefilter(action="default", category=100)                 # Not understandable
warnings.simplefilter(action="default", category=3.14)                # Not understandable
warnings.simplefilter(action="default", category=3.14+0.j)          # Not understandable
warnings.simplefilter(action="default", category=True)                # Not understandable

print(warnings.filters)
# [('default', None, True, None, 0),
#  ('default', None, (3.14+0j), None, 0),
#  ('default', None, 100, None, 0),
#  ('default', None, 'Hello World', None, 0),
#  ('default', None, <class 'Warning'>, None, 0)]

So, category argument of warnings.simplefilter() should also return the error message as shown below:

AssertionError: category must be a class

從報告中展示的入口 warnings.simplefilter() 和 warnings.filterwarnings() 開始，比較它們各自如何驗證 category 引數。使用無效值重現這些範例，並確認 simplefilter() 會引發與 filterwarnings() 相同的 category 驗證錯誤。
