The question is as it is in the 'Title', but for the sake of completeness -
Suppose :
>>> a= 23
>>> h ="Liam Neeson"
>>> k ={'a','b','c'}
Are three variables. Then I do a whole bunch of other stuff. And I want to see what variables I have initialised so far, is there a way to do it? Something that will return
[a,h,k].
If you only want user defined variables, you could use dir and strip out the builtins:
set(dir()) - set(dir(__builtins__)) - {'__builtins__'}
Demo:
>>> a = 23
>>> h = "Liam Neeson"
>>> k = {'a', 'b', 'c'}
>>> set(dir()) - set(dir(__builtins__)) - {'__builtins__'}
{'a', 'h', 'k'}
yes, using the dir() function:
dir([object]) Without arguments, return the list of names in the current local scope. With an argument, attempt to return a list of valid attributes for that object.
example:
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__']
>>> a = 1
>>> dir()
['__builtins__', '__doc__', '__name__', '__package__', 'a']
