合并列表中具有相同键的字典

Question

我有一个字典列表：

#NoEnv
#Warn
#SingleInstance Force
#UseHook
SetWorkingDir %A_ScriptDir%
SendMode Input

Global aKeysToFreeze := { LShift: false, a: false }, isFreezeOn := false

`::fToggleFreeze()

^`:: ; You can use this to check the logical state of the key
If GetKeyState("a")
    msgbox Key is pressed.
else msgbox Key is not pressed.
return

fToggleFreeze() {
    Local
    Global aKeysToFreeze, isFreezeOn
    
    If isFreezeOn {                          ; If there are frozen keys,
        For sKeyName, isKeyFrozen in aKeysToFreeze {
            Send % "{" sKeyName " Up}"       ; send key up event for each key and
            aKeysToFreeze[sKeyName] := false ; set the each key's frozen state to false
        }
    } else {
        For sKeyName, isKeyFrozen in aKeysToFreeze
            If GetKeyState(sKeyName, "P")     ; If the key is physically pressed
                aKeysToFreeze[sKeyName] := true  ; set frozen state to true
    }
    isFreezeOn := !isFreezeOn    ; Frozen mode toggle
}

*a::Send {Blind}{a DownR}
*LShift:: Send {Blind}{LShift DownR}

#If !aKeysToFreeze["a"] ; If the key is frozen, the key up hotkey is blocked
*a Up::Send {Blind}{a Up}

#If !aKeysToFreeze["LShift"]
*LShift Up::Send {Blind}{LShift Up}
#If

我需要像这样用相同的键连接所有字典：

bids_copy = [{'price': 1, 'quantity': 2}, {'price': 1, 'quantity': 5}, {'price': 2, 'quantity': 6}, {'price': 2, 'quantity': 2}]
bids_snapshot = []

我编写了一个无法按我希望的方式工作的函数：

print(bids_snapshot)
---> [{'price': 1, 'quantity': 7}, {'price': 2, 'quantity': 8}]

请帮忙，第三天我一直无法解决这个问题。
