于其中, 用单下划线 _ 起始的命名, 像 _name 等等这般, 属于一种大家向来都这么做的固有规范, 并非是语言强硬要求的语法准则。它主要是用来给代码的阅读者, 涵盖未来的你自己, 传递特定的意向。当存在一个变量, 或者是一个方法, 又或者是一个属性, 只要它是以 _ 开头的, 那么它就会向其他开发者传达这样的信息: “眼下这是属于一个内部实现的细节部分, 绝对千万不要在类的外部直接去进行访问, 也绝对不可拿去修改它”。class BankAccount: def __init__(self, balance): self._balance balance # 内部余额外部不应直接修改 self._transaction_count 0 def deposit(self, amount): self._balance amount

self._calculate_interest()在这段代码中调用者应使用和而不是直接访问或。多数现代的IDE, 像是某些特定的IDE, 在进行代码补全这个操作的时候, 会按照默认的设置, 把那些以_开头的成员给隐藏起来, 只有当手动键入下划线的情况下, 这些成员才会显示出来。这样的情况从工具的相关层面, 对“内部使用”的提示起到了强化的作用。Www.lpdvwx.cn/Article/details/3236453.sHtMLWww.lpdvwx.cn/Article/details/5829239.sHtMLWww.lpdvwx.cn/Article/details/1742308.sHtMLWww.lpdvwx.cn/Article/details/1566299.sHtMLWww.lpdvwx.cn/Article/details/3876813.sHtMLWww.lpdvwx.cn/Article/details/1825847.sHtMLWww.lpdvwx.cn/Article/details/7645047.sHtMLWww.lpdvwx.cn/Article/details/6677435.sHtMLWww.lpdvwx.cn/Article/details/3586770.sHtMLWww.lpdvwx.cn/Article/details/4804018.sHtMLWww.lpdvwx.cn/Article/details/6136538.sHtMLWww.lpdvwx.cn/Article/details/7689791.sHtMLWww.lpdvwx.cn/Article/details/2155695.sHtMLWww.lpdvwx.cn/Article/details/4278773.sHtMLWww.lpdvwx.cn/Article/details/3801944.sHtMLWww.lpdvwx.cn/Article/details/2594045.sHtMLWww.lpdvwx.cn/Article/details/3816261.sHtMLWww.lpdvwx.cn/Article/details/5841846.sHtMLWww.lpdvwx.cn/Article/details/9441855.sHtMLWww.lpdvwx.cn/Article/details/7478417.sHtMLWww.lpdvwx.cn/Article/details/9996316.sHtMLWww.lpdvwx.cn/Article/details/3042736.sHtMLWww.lpdvwx.cn/Article/details/5432773.sHtMLWww.lpdvwx.cn/Article/details/1092117.sHtMLWww.lpdvwx.cn/Article/details/8294823.sHtMLWww.lpdvwx.cn/Article/details/7994413.sHtMLWww.lpdvwx.cn/Article/details/1463145.sHtMLWww.lpdvwx.cn/Article/details/9261395.sHtMLWww.lpdvwx.cn/Article/details/7935014.sHtMLWww.lpdvwx.cn/Article/details/6715785.sHtMLWww.lpdvwx.cn/Article/details/3805014.sHtMLWww.lpdvwx.cn/Article/details/4075432.sHtMLWww.lpdvwx.cn/Article/details/9699868.sHtMLWww.lpdvwx.cn/Article/details/7378849.sHtMLWww.lpdvwx.cn/Article/details/1206193.sHtMLWww.lpdvwx.cn/Article/details/5896285.sHtMLWww.lpdvwx.cn/Article/details/6385703.sHtMLWww.lpdvwx.cn/Article/details/6556827.sHtMLWww.lpdvwx.cn/Article/details/1324245.sHtMLWww.lpdvwx.cn/Article/details/5235201.sHtMLWww.lpdvwx.cn/Article/details/8818803.sHtMLWww.lpdvwx.cn/Article/details/8896239.sHtMLWww.lpdvwx.cn/Article/details/3829257.sHtMLWww.lpdvwx.cn/Article/details/6731458.sHtMLWww.lpdvwx.cn/Article/details/4559488.sHtMLWww.lpdvwx.cn/Article/details/5657608.sHtMLWww.lpdvwx.cn/Article/details/7730974.sHtMLWww.lpdvwx.cn/Article/details/1707186.sHtMLWww.lpdvwx.cn/Article/details/6159137.sHtMLWww.lpdvwx.cn/Article/details/2063158.sHtMLWww.lpdvwx.cn/Article/details/3160664.sHtMLWww.lpdvwx.cn/Article/details/1563222.sHtMLWww.lpdvwx.cn/Article/details/1170938.sHtMLWww.lpdvwx.cn/Article/details/3330695.sHtMLWww.lpdvwx.cn/Article/details/9197109.sHtMLWww.lpdvwx.cn/Article/details/4549647.sHtMLWww.lpdvwx.cn/Article/details/9981792.sHtMLWww.lpdvwx.cn/Article/details/1449661.sHtMLWww.lpdvwx.cn/Article/details/6868069.sHtMLWww.lpdvwx.cn/Article/details/5427384.sHtMLWww.lpdvwx.cn/Article/details/6702941.sHtMLWww.lpdvwx.cn/Article/details/2253021.sHtMLWww.lpdvwx.cn/Article/details/2189208.sHtMLWww.lpdvwx.cn/Article/details/7974035.sHtMLWww.lpdvwx.cn/Article/details/8084066.sHtMLWww.lpdvwx.cn/Article/details/3619938.sHtMLWww.lpdvwx.cn/Article/details/2124001.sHtMLWww.lpdvwx.cn/Article/details/8039351.sHtMLWww.lpdvwx.cn/Article/details/1381756.sHtMLWww.lpdvwx.cn/Article/details/9728761.sHtMLWww.lpdvwx.cn/Article/details/3898242.sHtMLWww.lpdvwx.cn/Article/details/5739047.sHtMLWww.lpdvwx.cn/Article/details/3302720.sHtMLWww.lpdvwx.cn/Article/details/7259480.sHtMLWww.lpdvwx.cn/Article/details/6140678.sHtMLWww.lpdvwx.cn/Article/details/2039918.sHtMLWww.lpdvwx.cn/Article/details/6359914.sHtMLWww.lpdvwx.cn/Article/details/8761951.sHtMLWww.lpdvwx.cn/Article/details/8192592.sHtMLWww.lpdvwx.cn/Article/details/8562820.sHtMLWww.lpdvwx.cn/Article/details/8929042.sHtMLWww.lpdvwx.cn/Article/details/8072195.sHtMLWww.lpdvwx.cn/Article/details/2686232.sHtMLWww.lpdvwx.cn/Article/details/4880035.sHtMLWww.lpdvwx.cn/Article/details/9570462.sHtMLWww.lpdvwx.cn/Article/details/1804661.sHtMLWww.lpdvwx.cn/Article/details/1694314.sHtMLWww.lpdvwx.cn/Article/details/7031826.sHtMLWww.lpdvwx.cn/Article/details/5949882.sHtMLWww.lpdvwx.cn/Article/details/4574701.sHtMLWww.lpdvwx.cn/Article/details/7801261.sHtMLWww.lpdvwx.cn/Article/details/4017517.sHtMLWww.lpdvwx.cn/Article/details/2597831.sHtMLWww.lpdvwx.cn/Article/details/5992681.sHtMLWww.lpdvwx.cn/Article/details/1280885.sHtMLWww.lpdvwx.cn/Article/details/7322741.sHtMLWww.lpdvwx.cn/Article/details/5354601.sHtMLWww.lpdvwx.cn/Article/details/4904750.sHtMLWww.lpdvwx.cn/Article/details/6288370.sHtMLWww.lpdvwx.cn/Article/details/5976298.sHtMLWww.lpdvwx.cn/Article/details/4049428.sHtMLWww.lpdvwx.cn/Article/details/1749962.sHtMLWww.lpdvwx.cn/Article/details/3709850.sHtMLWww.lpdvwx.cn/Article/details/6883916.sHtMLWww.lpdvwx.cn/Article/details/2760959.sHtMLWww.lpdvwx.cn/Article/details/8766249.sHtMLWww.lpdvwx.cn/Article/details/9179494.sHtMLWww.lpdvwx.cn/Article/details/3939410.sHtMLWww.lpdvwx.cn/Article/details/8246571.sHtMLWww.lpdvwx.cn/Article/details/9303057.sHtMLWww.lpdvwx.cn/Article/details/9342326.sHtMLWww.lpdvwx.cn/Article/details/6921902.sHtMLWww.lpdvwx.cn/Article/details/2550165.sHtMLWww.lpdvwx.cn/Article/details/3576483.sHtMLWww.lpdvwx.cn/Article/details/8533324.sHtMLWww.lpdvwx.cn/Article/details/782727
