globals() method returns a dictionary that contains all the names of global scope. You can use this to create a variable whose name is stored in another variable. Something like this:
>>> var = 'abc'
>>> globals()
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', 'var': 'abc', '__doc__': None, '__package__': None}
>>> globals()[var] = {}
>>> abc
{}
>>> globals()
{'abc': {}, '__builtins__': <module '__builtin__' (built-in)>, '__package__': None, 'var': 'abc', '__name__': '__main__', '__doc__': None}
>>> abc['p0'] = 2
>>> abc
{'p0': 2}

locals() is the safer choise if used in a scope.

@Iskren I originally mentioned
locals() but later found that it has problem as specified here: stackoverflow.com/a/8028772/377953What do you mean? Assign var to a dictionary where 'name' evaluates to 'abc'? In that case,
var = {'name': 'abc'}
Otherwise, I have no idea what you're asking.
