Why i can't get the values in the items in dir() with loop:
for item in dir():
print(item)
It just print
__builtins__
__doc__
__loader__
__name__
__package__
__spec__
So, how can i use loop to print the value in item, i.e "__main__" in __name__
Thanks!
Calling dir without the argument is logically equivalent to list(locals()), as in getting the list of names of variables in the current namespace (keys of locals() dictionary).
You'd use the items method of locals() instead:
In [5]: for name, value in list(locals().items()):
...: print(name, value)
...:
vaultah's answer is best, I think, but you could also use eval to get the values:
for item in dir():
print('{} : {}'.format(item, eval(item)))
There is usually a lot of stigma regarding the use of eval (it's dangerous!) and I will probably be downvoted for this answer, however, I think that it OK in this limited case.
