如何从python列表中删除字符

Question

I have the follow python code which is a list. For some reason I get unwanted characters in the list how can we remove these characters from the beginning and end of list.

stuff = []
a = ('{"type": "push"}')
stuff.append(a)

print(stuff)

outputs

['{"type": "push"}']

How can we remove the [''] and output like

{"type": "push"}

Answer 1

By doing the following :

 a = ('{"type": "push"}')

you are appending a string ( type(a) returns str ). What you might want instead is to append a dictionary

a = {"type": "push"}    # ===> output = [{"type": "push"}]

which will give you the right output

Answer 2

I think you are assuming that a will be a tuple. However, that's not the case. In your current implementation it will be a string. That's why when you append(a) the whole string gets appended. Use any other data structures and there is no need of extra quotes that you don't require to be present.
