I like the explicit nature of Python's imports.

And especially how I can choose the best way to indicate the sources of names in my code:

   import time
   t = time.perf_counter()

   import time, my_module
   t1 = time.perf_counter()
   t2 = my_module.perf_counter()

   from time import perf_counter as std_counter
   from my_module import perf_counter as my_counter
   t1 = std_counter()
   t2 = my_counter()

   try:
       from my_module import perf_counter
   except ImportError:
       # Fall back to standard implementation
       from time import perf_counter
   t = perf_counter()

   # import time as m  
   import my_module as m
   t = m.perf_counter()
