Getting key with maximum value in dictionary?
...
You can use operator.itemgetter for that:
import operator
stats = {'a':1000, 'b':3000, 'c': 100}
max(stats.iteritems(), key=operator.itemgetter(1))[0]
And instead of building a new list in memory use stats.iteritems(). The key parameter to the max() function is a function that computes a key t...
Python time measure function
...()
print '%s function took %0.3f ms' % (f.func_name, (time2-time1)*1000.0)
return ret
return wrap
And the usage is very simple, just use the @timing decorator:
@timing
def do_work():
#code
Python 3:
def timing(f):
def wrap(*args, **kwargs):
time1 = time.time()

You may also need to set "overflow" but probably not.
This works because:
The !important declaration, combined with min-width cause everything to stay on the same line in IE...
