and a few new standard exceptions have been added. The obsolete AccessError exception has been deleted. Because it is possible (although unlikely) that this change broke existing code, the Python interpreter can be invoked the command line option-Xto disable this feature, and use string exception...
Formatter objects are used by the Python logging handlers to enhance the information available through LogRecord attributes. Python Standard Library provides logging.Formatter() function that takes string entries as a single parameter. exampleFormatter = logging.Formatter('%(asctime)s - %(name)s - ...
This means that synchronous and asynchronous functions/callables are different types - you can't just mix and match them. Try to await a sync function and you'll see Python complain, forget to await an async function and you'll get back a coroutine object rather than the result you wanted...
max()、min()、sum()这三个内置函数分别用于计算列表、元组或其他可迭代对象中所有元素最大值、最小值以及所有元素之和,sum()只支持数值型元素的序列或可迭代对象,max()和min()则要求序列或可迭代对象中的元素之间可比较大小。下面的代码首先使用列表推导式生成包含10个随机数的列表,然后分别计算该列表的最大值...
