Question

这是我的代码

this_item = "1234"     
this_is_a_list = []
for item in this_is_a_list:
    if this_item == item:
        print("this item is already in the list")
    else:
        this_is_a_list.append(str(this_item))
        print("I want to create a new variable with the name of this_item")

我要执行的操作是检查this_item是否在this_is_a_list中，如果是，请执行类似打印“此项目已在列表中”的操作，但是如果该项目不在this_is_a_list中，则我要创建一个名为this_item等于的新变量，我希望该变量等于0。仅就上下文而言，this_item可能会发生很大变化。

改为使用字典：

myDict = {}
this_item = "1234"     
this_is_a_list = []
for item in this_is_a_list:
    if this_item == item:
        print("this item is already in the list")
    else:
        #this_is_a_list.append(str(this_item))
        #print("I want to create a new variable with the name of this_item")
        myDict[str(this_item)] = 0

稍后您可以检索以下值：

print(myDict['1234'])

如何通过循环创建变量
