python - 将 python 对象转换为字符串，编辑它并转换回原始类型的对象

Question

晚上好，我有这种类型的 python 对象。这里有什么方法可以将它转换为字符串、编辑并转换回来吗？

 <class 'matplotlib.transforms.CompositeGenericTransform'>

当我通过 print(variable) 打印它时，它看起来像这样:

CompositeGenericTransform(CompositeGenericTransform(CompositeGenericTransform(CompositeGenericTransform(CompositeGenericTransform(TransformWrapper(BlendedAffine2D(IdentityTransform(),IdentityTransform())), CompositeGenericTransform(BboxTransformFrom(TransformedBbox(Bbox('array([[ -19.5      ,  -10.7983871],\n       [ 221.5      ,  140.7983871]])'), TransformWrapper(BlendedAffine2D(IdentityTransform(),IdentityTransform())))), BboxTransformTo(TransformedBbox(Bbox('array([[ 0.125,  0.25 ],\n       [ 0.9  ,  0.9  ]])'), BboxTransformTo(TransformedBbox(Bbox('array([[ 0.,  0.],\n       [ 8.,  6.]])'), Affine2D(array([[ 80.,   0.,   0.],
       [  0.,  80.,   0.],
       [  0.,   0.,   1.]])))))))), Affine2D(array([[ 0.99968918, -0.02493069,  6.98903935],
       [ 0.02493069,  0.99968918, -8.59039721],
       [ 0.        ,  0.        ,  1.        ]]))), Affine2D(array([[ 0.99968918, -0.02493069,  6.93499095],
       [ 0.02493069,  0.99968918, -7.14592338],
       [ 0.        ,  0.        ,  1.        ]]))), Affine2D(array([[ 0.99968918, -0.02493069,  6.88226449],
       [ 0.02493069,  0.99968918, -6.30113809],
       [ 0.        ,  0.        ,  1.        ]]))), Affine2D(array([[ 0.99968918, -0.02493069,  6.96735103],
       [ 0.02493069,  0.99968918, -7.27368166],
       [ 0.        ,  0.        ,  1.        ]])))

你可以用 Pickle 做到这一点，它是 Python 的对象序列化库。
