@ladypxy 完，理解错你的意思了
你要的是这个意思？
mylist = sorted(mylist)
newlist = []
templist = []
min = mylist[0]
max = mylist[len(mylist)-1]
delta = (max-min) / (N-1)
next = min + delta
j = 0
for i in mylist:
if i <= next:
templist.append(i)
if i >= next:
newlist.append(templist)
next = next+delta
templist = []
templist.append(i)
j += 1
if j == len(mylist):
newlist.append(templist)

print(newlist)
