Question

我有2个数据集。

let tabViewController =
storyboard?.instantiateViewController(withIdentifier: "TabController") as? TabController
view.window?.rootViewController = tabViewController
view.window?.makeKeyAndVisible()

输出：

dict1 =pd.DataFrame({'Name' : ['A','B','C','D'], 'Score' : [19,20,11,12]})
list1 =pd.DataFrame(['Math', 'English', 'History', 'Science'])
concat_data = pd.concat([dict1,list1])

我正在寻找的输出：

Name  Score        0
0    A   19.0      NaN
1    B   20.0      NaN
2    C   11.0      NaN
3    D   12.0      NaN
0  NaN    NaN     Math
1  NaN    NaN  English
2  NaN    NaN  History
3  NaN    NaN  Science

有人可以帮我吗？

您需要做的就是传递正确的class SudokuAlgorithm { public string[,] sudokuFields; public string[,] sudokuUnsolved; public bool corectRow; public bool correctColumn; public bool correctField; private static int UNASSIGNED = 0; public SudokuAlgorithm() { sudokuFields = new string[9, 9]; } public SudokuAlgorithm(string[,] sudoku, int indexRow, int indexColumn) { this.sudokuFields = sudoku; sudokuUnsolved = sudoku; correctRow = TestRow(indexRow, indexColumn); correctColumn = TestColumn(indexRow, indexColumn); correctField = TestArea(indexRow, indexColumn); SolveSudoku(); } private void SolveSudoku() { for(int i=0;i<9;i++) //Column { for(int j=0;j<9;j++) // Row { if(SudokuFieldFree(j,i) == true) { for(int k=1;k<=9;k++) { sudokuFields[i, j] = k.ToString(); if(TestRow(j,i) == false || TestColumn(j,i) == false || TestArea(j,i) == false) { sudokuField[i, j] = ""; } else { break; } } if (sudokuFields[i, j] == "") { if(j!=0) { for(int l =j-1;l>=0;l--) { if (SudokuAreaFreeUnsolved(l, i) == true) { j = l-1; sudokuFields[i, l] = ""; break; } } } else { i = i - 1; j = 8; } } } } } } private bool SudokuAreaFree(int indexRow, int indexColumn) { bool free= false; if (sudokuFields[indexColumn, indexRow] == "" || sudokuFields[indexColumn, indexRow] == " " || sudokuFields[indexColumn, indexRow] == null) { free = true;

return free; } return free; } private bool TestRow(int indexRow, int indexColumn) { bool valid = true; for (int i = 0; i < 9; i++) { for (int j = 0; j < 9; j++) { if (sudokuFields[i, indexRow] == sudokuFields[j, indexRow] && sudokuFields[i, indexRow] != " " && i != j) { valid = false;

return valid; } } } } else if (indexColumn >= 3 && indexColumn <= 5 && indexRow >= 0 && indexRow <= 2) { for (int i = 3; i < 6; i++) { for (int j = 0; j < 3; j++) { if (sudokuFields[indexColumn, indexRow] == sudokuFields[i, j] && sudokuFields[indexColumn, indexRow] != " " && indexColumn != i && indexRow != j) { valid = false; return valid; } } } } else if (indexColumn >= 6 && indexColumn <= 8 && indexRow >= 0 && indexRow <= 2) { for (int i = 6; i < 9; i++) { for (int j = 0; j < 3; j++) { if (sudokuFields[indexColumn, indexRow] == sudokuFields[i, j] && sudokuFields[indexColumn, indexRow] != " " && indexColumn != i && indexRow != j) { valid = false;

return valid; } } } } else if (indexColumn >= 6 && indexColumn <= 8 && indexRow >= 3 && indexRow <= 5) { for (int i = 6; i < 9; i++) { for (int j = 3; j < 6; j++) { if (sudokuFields[indexColumn, indexRow] == sudokuFields[i, j] && sudokuFields[indexColumn, indexRow] != " " && indexColumn != i && indexRow != j) { valid = false;

return valid; } } } } return valid; } }。 default behavior for concat是axis，这意味着操作需要按索引或行进行，而您则需要按列进行操作：

轴：{0 /“索引”，1 /“列”}，默认为0 要沿着的轴。

axis=0

输出：

concat_data = pd.concat([dict1,list1],axis=1)
print(concat_data)

合并多个没有通用列的数据框
