from __future__ import division
somelist = [1,12,2,53,23,6,17]
max_value = max(somelist)
min_value = min(somelist)
avg_value = 0 if len(somelist) == 0 else sum(somelist)/len(somelist)
如果要手动查找最小值作为函数：
somelist = [1,12,2,53,23,6,17]
def my_min_function(somelist):
min_value = None
for value in somelist:
if not min_value:
min_value = value
elif value < min_value:
min_value = value
return min_value
Python 3.4引入了该statistics软件包，该软件包提供了mean其他统计信息：
from statistics import mean, median
somelist = [1,12,2,53,23,6,17]
avg_value = mean(somelist)
median_value = median(somelist)
