In the for loop I have a dictionary object like this:
在 for 循环中，我有一个像这样的字典对象：
mob1 = {
"Item": item1,
'Price': price1,
'Desc': desc1
}
and I tried to append it like:
我尝试将其附加如下：
list.append(mob1)
I get the following error:
我收到以下错误：
Traceback (most recent call last):
File "/home/turbolab/Documents/python_test/Sep 23 data_to_json test.json", line 32, in <module>
list.append(mob1)

回答by zvone
listis a class. appendis a method of that class which has to be called on instances of list.
list是一个类。append是该类的一个方法，必须在 的实例上调用list。
list.append(7) # error
mylist = list()
mylist.append(7) # ok
回答by mengg
Have you tried list.append([mob1['Item'],mob1['Price'],mob1['Desc']])?
你试过list.append([mob1['Item'],mob1['Price'],mob1['Desc']])吗？
