Python相当于$ this - > $ varName

Question

在PHP中,我可以执行以下操作:

$myVar = 'name';

print $myClass->$myVar;
// Identical to $myClass->name

我希望在Python中这样做,但无法找到方法

Answer 1

在python中,它是getattr内置函数.

class Something( object ):
    def __init__( self ):
        self.a= 2
        self.b= 3

x= Something()
getattr( x, 'a' )
getattr( x, 'b' )

Answer 2

您将需要使用getattr内置函数.

myvar = 'name'

//both should produce the same results
value = obj.name
value = getattr(obj, myvar)
