Question

在Python 3和Python 2中，__repr__是否应该返回字节或unicode？参考和报价是理想的。

Here's some information大约2-3兼容性，但我没有看到答案。

Answer 1

类型为function getStats() { var url = "https://stats.nba.com/stats/leaguedashplayerstats?College=&Conference=&Country=&DateFrom=&DateTo=&Division=&DraftPick=&DraftYear=&GameScope=&GameSegment=&Height=&LastNGames=0&LeagueID=00&Location=&MeasureType=Base&Month=0&OpponentTeamID=0&Outcome=&PORound=0&PaceAdjust=N&PerMode=Totals&Period=0&PlayerExperience=&PlayerPosition=&PlusMinus=N&Rank=N&Season=2017-18&SeasonSegment=&SeasonType=Regular+Season&ShotClockRange=&StarterBench=&TeamID=0&VsConference=&VsDivision=&Weight="; var api = url; fetch(api) .then(function(response){ return response.json(); }) .then(function(data){ console.log(data); }) .catch(function(error){ console.log("There is an error.", error); }) }（对于python2.x和python3.x）：

str

必须如此，因为>>> type(repr(object())) <class 'str'>默认调用__str__如果前者不存在，但__repr__ 返回{{1} }}

对于那些不知道的人，在python3.x中，__str__是表示unicode的类型。在python2.x中，str是表示字节的类型。

这两种语言的Python 3.6.4 (default, Dec 21 2017, 18:54:30) >>> type(repr(())) <class 'str'> Python 2.7.14 (default, Nov 7 2017, 17:59:11) >>> type(repr(())) <type 'str'>：
