I am writing a python script that requires a reverse complement function to be called on DNA strings of length 1 through around length 30. Line profiling programs indicate that my functions spend a lot of time getting the reverse complements, so I am looking to...

语法:sorted(iterable, key=None, reverse=False),iterable-可迭代对象,key-用来进行比较的元素,可以将key指定为一个函数,把可迭代对象的元素作为入参,使用返回的结果来进行排序,reverse-排序方式,True为降序,False为升序,默认为False 返回值:返回一个新的经过排序后的list...
In this tutorial, you'll explore Python's __pycache__ folder. You'll learn about when and why the interpreter creates these folders, and you'll customize their default behavior. Finally, you'll take a look under the hood of the cached .pyc files.
You can even do the reverse of the previous operation. If you have a time string that you want to convert to a time tuple, you can use the strptime() function, which parses a string representing a date and time and returns a time tuple. You can then use the time tuple to extract ...
Protocols.Protocols like theHypertext Transfer Protocoland internet remote function calls use parsers. Parser generator.Parser generators take grammar as input and generate source code, which is parsing in reverse. They construct parsers from regular expressions, which are special strings used to manage ...
