Tkinter Treeview使用get_children（）追加到列表

Question

I want to 'save' the contents of the treeview into a list which I can display again. Just like 'settings'.

for child in self.terminal_tree.get_children():
    print(self.terminal_tree.item(child)["values"])

    machine_ports = []
    machine_ports.append(self.terminal_tree.item(child)["values"])
    print(machine_ports)

The output I get is:

['abc', 123]
[['abc', 123]]
['hjk', 456]
[['hjk', 456]]

The output that I want is [['abc', 123], ['hjk', 456]]

Answer 1

Simply put:

machine_ports = []

above for loop:

machine_ports = []
for child in self.terminal_tree.get_children():
    print(self.terminal_tree.item(child)["values"])
    machine_ports.append(self.terminal_tree.item(child)["values"])
    print(machine_ports)
