基于、中()的不同用法介绍这个句子没法按照要求改写, 因为它本身不是一个完整的表达语义的句子。今天, 小编要为大家分享一篇介绍, 是基于中的不同运用的那种, 而且它具备很好的可供参考所用的价值。希望这对大家能产生帮助。大家一起跟着小编过来瞧一瞧。() 简介作用用于重新载入之前载入的模块语法格式()参数为模块对象必须已经被加载返回值返回模块对象注意事项多次反复运用语句之际, 不会再度载入被指定好了的模块哩, 仅仅是将针对该一个模块的内存地址给引用进本地变量的环境之中而已哟。多数的模块设计成仅加载一回, 再度加载兴许会引发某些问题, 由此, 谨慎使用()。使用sys.可查看已加载的模块。在中()为内置函数。例重设字符编码import sys sys.getdefaultencoding() # 当前默认编码 ascii reload(sys) # 使用 reload sys.setdefaultencoding(utf8) # 设置编码 sys.getdefaultencoding() utf8 sys.setdefaultencoding(utf8) # 设置编码 sys.getdefaultencoding() utf8 在中()被转移到imp模块以及模块中。之前, 在那个imp里面, 是处于.4这个阶段, 而在.4之后, imp模块是逐渐地逐步被废弃掉了, 然后, 是被移到模块当中去了。 import sys reload(sys) Traceback (most recent call last): File , line 1, in NameError: name reload is not defined from imp import reload __main__:1: DeprecationWarning: the imp module is deprecated in favour of importlib; see the modules documentation for alternative uses reload(sys) from importlib import reload reload(sys), line 1, in NameError: name reload is not defined from imp import reload __main__:1: DeprecationWarning: the imp module is deprecated in favour of importlib; see the modules documentation for alternative uses reload(sys) from importlib import reload reload(sys)以上这篇, 是基于、中的不同用法介绍, 这就是小编分享给大家的全部内容了, 希望能给大家一个参考, 且希望大家多多支持我谢谢。Csdn.tphep.cN/Article/details/91896.shtmlCsdn.tphep.cN/Article/details/00920.shtmlCsdn.tphep.cN/Article/details/28044.shtmlCsdn.tphep.cN/Article/details/59032.shtmlCsdn.tphep.cN/Article/details/56467.shtmlCsdn.tphep.cN/Article/details/50632.shtmlCsdn.tphep.cN/Article/details/13983.shtmlCsdn.tphep.cN/Article/details/94436.shtmlCsdn.tphep.cN/Article/details/19206.shtmlCsdn.tphep.cN/Article/details/27787.shtmlCsdn.tphep.cN/Article/details/53446.shtmlCsdn.tphep.cN/Article/details/53130.shtmlCsdn.tphep.cN/Article/details/56869.shtmlCsdn.tphep.cN/Article/details/26212.shtmlCsdn.tphep.cN/Article/details/96783.shtmlCsdn.tphep.cN/Article/details/66956.shtmlCsdn.tphep.cN/Article/details/94677.shtmlCsdn.tphep.cN/Article/details/13667.shtmlCsdn.tphep.cN/Article/details/16113.shtmlCsdn.tphep.cN/Article/details/28861.shtmlCsdn.tphep.cN/Article/details/06751.shtmlCsdn.tphep.cN/Article/details/28604.shtmlCsdn.tphep.cN/Article/details/70827.shtmlCsdn.tphep.cN/Article/details/37226.shtmlCsdn.tphep.cN/Article/details/05192.shtmlCsdn.tphep.cN/Article/details/42211.shtmlCsdn.tphep.cN/Article/details/69378.shtmlCsdn.tphep.cN/Article/details/46156.shtmlCsdn.tphep.cN/Article/details/63940.shtmlCsdn.tphep.cN/Article/details/21479.shtmlCsdn.tphep.cN/Article/details/30507.shtmlCsdn.tphep.cN/Article/details/24273.shtmlCsdn.tphep.cN/Article/details/72095.shtmlCsdn.tphep.cN/Article/details/84505.shtmlCsdn.tphep.cN/Article/details/25423.shtmlCsdn.tphep.cN/Article/details/01328.shtmlCsdn.tphep.cN/Article/details/22418.shtmlCsdn.tphep.cN/Article/details/01648.shtmlCsdn.tphep.cN/Article/details/35989.shtmlCsdn.tphep.cN/Article/details/97339.shtmlCsdn.tphep.cN/Article/details/48646.shtmlCsdn.tphep.cN/Article/details/20602.shtmlCsdn.tphep.cN/Article/details/10589.shtmlCsdn.tphep.cN/Article/details/65994.shtmlCsdn.tphep.cN/Article/details/35006.shtmlCsdn.tphep.cN/Article/details/47086.shtmlCsdn.tphep.cN/Article/details/39210.shtmlCsdn.tphep.cN/Article/details/44259.shtmlCsdn.tphep.cN/Article/details/37374.shtmlCsdn.tphep.cN/Article/details/32817.shtmlCsdn.tphep.cN/Article/details/32651.shtmlCsdn.tphep.cN/Article/details/03077.shtmlCsdn.tphep.cN/Article/details/08462.shtmlCsdn.tphep.cN/Article/details/95962.shtmlCsdn.tphep.cN/Article/details/08505.shtmlCsdn.tphep.cN/Article/details/34717.shtmlCsdn.tphep.cN/Article/details/84501.shtmlCsdn.tphep.cN/Article/details/26231.shtmlCsdn.tphep.cN/Article/details/91709.shtmlCsdn.tphep.cN/Article/details/68154.shtmlCsdn.tphep.cN/Article/details/20444.shtmlCsdn.tphep.cN/Article/details/32444.shtmlCsdn.tphep.cN/Article/details/87530.shtmlCsdn.tphep.cN/Article/details/06981.shtmlCsdn.tphep.cN/Article/details/42657.shtmlCsdn.tphep.cN/Article/details/45127.shtmlCsdn.tphep.cN/Article/details/18940.shtmlCsdn.tphep.cN/Article/details/79388.shtmlCsdn.tphep.cN/Article/details/47497.shtmlCsdn.tphep.cN/Article/details/96672.shtmlCsdn.tphep.cN/Article/details/38841.shtmlCsdn.tphep.cN/Article/details/97008.shtmlCsdn.tphep.cN/Article/details/75173.shtmlCsdn.tphep.cN/Article/details/74165.shtmlCsdn.tphep.cN/Article/details/33631.shtmlCsdn.tphep.cN/Article/details/22099.shtmlCsdn.tphep.cN/Article/details/49427.shtmlCsdn.tphep.cN/Article/details/12509.shtmlCsdn.tphep.cN/Article/details/78909.shtmlCsdn.tphep.cN/Article/details/00608.shtmlCsdn.tphep.cN/Article/details/52213.shtmlCsdn.tphep.cN/Article/details/04224.shtmlCsdn.tphep.cN/Article/details/08697.shtmlCsdn.tphep.cN/Article/details/95580.shtmlCsdn.tphep.cN/Article/details/54756.shtmlCsdn.tphep.cN/Article/details/15253.shtmlCsdn.tphep.cN/Article/details/20302.shtmlCsdn.tphep.cN/Article/details/85779.shtmlCsdn.tphep.cN/Article/details/45780.shtmlCsdn.tphep.cN/Article/details/23902.shtmlCsdn.tphep.cN/Article/details/88724.shtmlCsdn.tphep.cN/Article/details/02428.shtmlCsdn.tphep.cN/Article/details/67192.shtmlCsdn.tphep.cN/Article/details/06002.shtmlCsdn.tphep.cN/Article/details/14104.shtmlCsdn.tphep.cN/Article/details/78507.shtmlCsdn.tphep.cN/Article/details/14905.shtmlCsdn.tphep.cN/Article/details/08314.shtmlCsdn.tphep.cN/Article/details/37584.shtmlCsdn.tphep.cN/Article/details/87071.shtmlCsdn.tphep.cN/Article/details/47104.shtmlCsdn.tphep.cN/Article/details/15270.shtmlCsdn.tphep.cN/Article/details/27609.shtmlCsdn.tphep.cN/Article/details/50564.shtmlCsdn.tphep.cN/Article/details/77305.shtmlCsdn.tphep.cN/Article/details/26287.shtmlCsdn.tphep.cN/Article/details/98594.shtmlCsdn.tphep.cN/Article/details/75127.shtmlCsdn.tphep.cN/Article/details/97360.shtmlCsdn.tphep.cN/Article/details/62370.shtmlCsdn.tphep.cN/Article/details/76844.shtmlCsdn.tphep.cN/Article/details/11868.shtmlCsdn.tphep.cN/Article/details/13995.shtmlCsdn.tphep.cN/Article/details/34158.shtmlCsdn.tphep.cN/Article/details/63379.shtmlCsdn.tphep.cN/Article/details/07766.shtmlCsdn.tphep.cN/Article/details/51698.shtmlCsdn.tphep.cN/Article/details/38688.shtmlCsdn.tphep.cN/Article/details/85033.shtmlCsdn.tphep.cN/Article/details/31509.shtmlCsdn.tphep.cN/Article/details/10650.shtmlCsdn.tphep.cN/Article/deta
