case pattern2: #当 subject 匹配 pattern2 时执行的代码块 statement(s) case _: #当 subject 不匹配前面任何模式时执行的代码块 statement(s) subject是要进行匹配的值。 pattern是各种匹配模式,Python 会依次将subject与每个pattern进行匹配。如果匹配成功,则执行对应的代码块,并跳过后续的匹配。 _是通配符模式,...

Structural Pattern Matching: 翻译过来应该是 结构化的模式匹配。从python 3.10开始提供了match statement。它远比简单的其它语言中的那种switch语句功能强大的多。 通过一个例子来了解一下这种语句的用法。 假设我们有一个函数,用来区分用户做的操作,并将其打印出来。 我们使用json结构的字符串来做为用户操作的内容并...
This can be simplified using Python’s new match statement released in Python 3.10.Here’s the same example again.import datetime intDay = datetime.datetime.today().weekday() days = ["mon", "tue", "wed", "thur", "fri", "sat", "sun"] match days[intDay]: case "mon": print("...
Python 3.9 版本确实不支持 match 语句。match 语句是在 Python 3.10 版本中引入的,用于替代传统的 if-elif-else 结构,提供了一种更简洁和强大的模式匹配机制。 针对您提出的问题,我将分点回答: 确认Python 3.9是否支持match语句: 不支持。match 语句是在 Python 3.10 及更高版本中引入的。 如果不支持,提供解...
If the search_string is found in the list, the index() method will return its index. In this case, the print(True) statement is executed, indicating that the search string was found. However, if the search_string is not present in the list, the index() method will raise a ValueError...
Describe the issue as clearly as possible: I'm not sure what the intended Python version support is, but you have python>=3.9 in the pyproject.toml so I assume its still supported. If I try to run a generation with outlines.generate.rege...
