While loops exist in virtually all programming languages, the Pythonforloop function is one of the easiest built-in functions to master since it reads almost like plain English.In this tutorial, we’ll cover every facet of theforloop. We’ll show you how to use it with a range of example...
如果推算的算法比较复杂,总类似列表生成式的for循环无法实现的时候,还可以用函数来实现。 The generator is very powerful. If the calculated algorithm is more complex, the "for loop" of the list generation is not realized, and the function can be used to realize it. 比如,著名的斐波拉契数列(Fibonacc...
This is for backwards compatibility: the logging package pre-dates newer formatting options such as str.format() and string.Template. if logger.isEnabledFor(logging.DEBUG): logger.debug('Message with %s, %s', expensive_func1(), expensive...

afterstep4. Implementation For backwards-compatibility with existing code which currently uses non-ASCII in string literals without declaring an encoding, the implementation will be introduced in two phases: 1. Allow non-ASCIIinstringliteralsandcomments,byinternally ...
'r' is for “read”; OK, big deal, we’re reading the file. Ah, but 'b' is for “binary.” Without the 'b' flag, this for loop would read the file, line by line, and convert each line into a string — an array of Unicode characters — according to the system default ...
The decision to implement many protocols as part of the core software burdens Twisted with maintaining code for all of those protocols. Implementations have to evolve with changing standards and the adoption of new protocols while maintaining a strict backwards-compatibility policy. Twisted is primarily...
