Different Methods for Converting a String to a List 1. Using split() The split() method is the most common way to convert a string into a list by breaking it at a specified delimiter. string = "apple,banana,cherry" list_of_fruits = string.split(",") print(list_of_fruits) # Output...

上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。

Advanced usage: If you have many sentences (say over a megabyte) to parse at once, you can avoid loading them into memory at once by usingparse_tree_incr()instead ofparse_tree. It takes an opened file, and returns a generator instead of the list directly, so you need to either iterate...
