问题问:“ 如何在Python 3中完成? ”在Python 3.x中使用以下结构:for item in [1,2,3,4]: print(item, " ", end="")这将生成:1 2 3 4有关更多信息,请参见此Python文档:Old: print x, # Trailing comma suppresses newlineNew: print(x, end=" ") # Appends a space instead of a newline-除了:此外,该print()功能还提供了sep一个参数,可让您指定应如何分隔要打印的单个项目。例如,In [21]: print('this','is', 'a', 'test') # default single space between itemsthis is a testIn [22]: print('this','is', 'a', 'test', sep="") # no spaces between itemsthisisatestIn [22]: print('this','is', 'a', 'test', sep="--*--") # user specified separationthis--*--is--*--a--*--test

因为python 3 print()函数允许end =“”定义,所以可以满足大多数问题。就我而言,我想使用PrettyPrint并感到沮丧,因为该模块未进行类似的更新。所以我做到了我想要的:from pprint import PrettyPrinterclass CommaEndingPrettyPrinter(PrettyPrinter): def pprint(self, object): self._format(object, self._stream, 0, 0, {}, 0) # this is where to tell it what you want instead of the default "\n" self._stream.write(",\n")def comma_ending_prettyprint(object, stream=None, indent=1, width=80, depth=None): """Pretty-print a Python object to a stream [default is sys.stdout] with a comma at the end.""" printer = CommaEndingPrettyPrinter( stream=stream, indent=indent, width=width, depth=depth) printer.pprint(object)现在,当我这样做时:comma_ending_prettyprint(row, stream=outfile)我得到了我想要的(代替您想要的-您的里程可能会有所不同)
