告诉我，我无法理解。为了测试，我赶紧勾勒，体验0..j2文件：

{% for group in groups['all'] %}
Host {{ group }}
User {{ ansible_user }}
{% endfor %}

主机文件：

[test1]
localhost1 ansible_host=localhost ansible_host_ip=127.0.0.1 ansible_user=arch1 ansible_connection=local
localhost2 ansible_host=localhost ansible_host_ip=127.0.0.2 ansible_user=test ansible_connection=local
localhost3 ansible_host=localhost ansible_host_ip=127.0.0.3 ansible_user=test ansible_connection=local
[test2]
localhost4 ansible_host=localhost ansible_host_ip=127.0.0.4 ansible_user=root1 ansible_connection=local

.yml 文件：

---
- name: Test SSH create
  hosts: all
  tasks:
    - name: Update Test SSH Jinja2
      template:
        src: /etc/ansible/temlates/ssh_test.j2
        dest: /etc/ansible/test

并输出：

Host localhost1
User test
Host localhost2
User test
Host localhost3
User test
Host localhost4
User test

为什么 ansible_user 总是一样的？他为什么不把它们一一放下？据我了解，这是因为 ansible_user 变量取自创建配置的主机。如何在不使用模块的情况下解决此问题？

有一个用Qt Designer制作的小应用程序，它有两个QTableWidget带有一些数据的表（DataTable_1, DataTable_2）。

我找到了适合我的解决方案 ( https://quares.ru/?id=193989 )，但不幸的是我无法为自己正确应用它。

我是这样做的：

import sys
from PyQt5 import QtWidgets, QtCore
import design

class ExampleApp(QtWidgets.QMainWindow, design.Ui_MainWindow):
def __init__(self):
    super().__init__()
    self.setupUi(self)
    self.deleteRow_1.clicked.connect(self.delete_row_1)
    self.addRow_1.clicked.connect(self.add_row_1)
    self.deleteRow_2.clicked.connect(self.delete_row_2)
    self.addRow_2.clicked.connect(self.add_row_2)

def keyPressEvent(self, event):
    super().keyPressEvent(event)
    if event.key() == QtCore.Qt.Key_C and (event.modifiers() & QtCore.Qt.ControlModifier):
        self.DataTable_1.copied_cells = sorted(self.DataTable_1.selectedIndexes())
    elif event.key() == QtCore.Qt.Key_V and (event.modifiers() & QtCore.Qt.ControlModifier):
        r = self.DataTable_1.currentRow() - self.DataTable_1.copied_cells[0].row()
        c = self.DataTable_1.currentColumn() - self.DataTable_1.copied_cells[0].column()
        for cell in self.DataTable_1.copied_cells:
            self.DataTable_1.setItem(cell.row() + r, cell.column() + c, QtWidgets.QTableWidgetItem(cell.data()))

def add_row_1(self):
    row_position = self.DataTable_1.rowCount()
    self.DataTable_1.insertRow(row_position)

def delete_row_1(self):
    rows = set()
    for index in self.DataTable_1.selectedIndexes():
        rows.add(index.row())
    for row in sorted(rows, reverse=True):
        self.DataTable_1.removeRow(row)

def add_row_2(self):
    row_position = self.DataTable_2.rowCount()
    self.DataTable_2.insertRow(row_position)

def delete_row_2(self):
    rows = set()
    for index in self.DataTable_2.selectedIndexes():
        rows.add(index.row())
    for row in sorted(rows, reverse=True):
        self.DataTable_2.removeRow(row)

def main():
    app = QtWidgets.QApplication(sys.argv)
    window = ExampleApp()
    window.show()
    app.exec_()


if __name__ == '__main__':
    main()

pastebin design.py 上的代码

使用 tableDataTable_1一切正常，但我不能对 table 做同样的事情DataTable_2。理想情况下，我还希望能够在表之间复制数据。谢谢你。
