{"library":"Sklearn","prompt":"Problem:\n\nI'd like to do some operations to my df. And there is an example below.\ndf\n\nCol1   Col2         Col3\n C      33     [Apple, Orange, Banana]\n A      2.5    [Apple, Grape]\n B      42     [Banana]\nafter the operations, the df is converted into\n\ndf\n\nCol1   Col2   Apple   Orange   Banana   Grape\n C      33     1        1        1       0\n A      2.5    1        0        0       1\n B      42     0        0        1       0\nGenerally, I want this pandas column which consisting of a list of String names broken down into as many columns as the unique names.\nMaybe it's like one-hot-encode them (note that value 1 representing a given name existing in a row and then 0 is absence).\nCould any one give me any suggestion of pandas or sklearn methods? thanks!\n\nA:\n\n<code>\nimport pandas as pd\nimport numpy as np\nimport sklearn\ndf = load_data()\n</code>\ndf_out = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
