Do you mean something like this?
 >>> import string
 >>> dir(string)
['Formatter', 'Template', '_TemplateMetaclass', '__builtins__', 
'__doc__', '__file__', '__name__', '__package__', '_multimap', '_re', 
'ascii_letters', 'ascii_lowercase', 'ascii_uppercase', 'capwords', 
'digits', 'hexdigits', 'maketrans', 'octdigits', 'printable', 
'punctuation', 'whitespace']
 >>> import math

 >>> math.__dict__.update(string.__dict__)
 >>> dir(math)
['Formatter', 'Template', '_TemplateMetaclass', '__builtins__', 
'__doc__', '__file__', '__name__', '__package__', '_multimap', '_re', 
'acos', 'acosh', 'ascii_letters', 'ascii_lowercase', 'ascii_uppercase', 
'asin', 'asinh', 'atan', 'atan2', 'atanh', 'capwords', 'ceil', 
'copysign', 'cos', 'cosh', 'degrees', 'digits', 'e', 'exp', 'fabs', 
'factorial', 'floor', 'fmod', 'frexp', 'hexdigits', 'hypot', 'isinf', 
'isnan', 'ldexp', 'log', 'log10', 'log1p', 'maketrans', 'modf', 
'octdigits', 'pi', 'pow', 'printable', 'punctuation', 'radians', 'sin', 
'sinh', 'sqrt', 'sum', 'tan', 'tanh', 'trunc', 'whitespace']
