python類里的私有變量如何定義？

Python沒有私有變量。任何定義的變量都可以直接調(diào)用。但是，一般來說，您可以在定義的變量前后添加兩個下劃線，以將此類變量視為專用變量，如以下代碼所示：

class person:defuuuuuuuinituuuuuuuu2self（self）：self.uuuuu2p=person（）print（“uuuuuu2privateuuuu1”，p.uuu2privateuuuu2）print（“p contains variables:”，（P）輸入：輸出：輸出：輸出：本公司的私營私營部門：100p包含變量：100p包含的輸出：輸出：輸出：輸出：輸出：輸出：輸出：輸出：輸出：輸出：輸出：輸出：100 P包含變量：包括“uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu100p包含變量：[“uuuuclass class classu ”、“ uuuuuclass class class class classu ”、、“ uuuuuuDELuuuuuuuuuclassclass”、“、、、、、““uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuclassclassclassclassclassuuuuuuuu“，”初始化“，”樂“，”lt“，”模塊“，”模塊目前，美國已經(jīng)有了一個UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU“““““““““““，，，，，，，““““““，，，，”，”，“UUUUUUUUUU變量將在賦值后創(chuàng)建value

]等號（=）用來給變量賦值

=左邊是變量名

=右邊是存儲在變量中的值

變量名=value

變量定義后，可以直接使用

示例：；！/usr/bin/Python

；-*-編碼：UTF-8-*-

counter=100#賦值整數(shù)變量

miles=1000.0#浮點

name=“John”#string

print counter

print miles

print name

輸出：

100

1000.0
