python中的奇数和偶数升序排序列表

Question

I have a list listOfNumbers = [3,2,1,4,5,6,7,8,9,22,25,16,17,28] I want to sort this list in ascending order but first of all odd number then even number like this:

[1, 5, 7, 9, 11, 15, 19, 29,'startOF->evens', 4, 8, 10, 14, 16, 28, 32, 66]

without sort function

I've tried this but I get an error

data_list = [3,2,1,4,5,6,7,8,9,22,25,16,17,28]
new_list = []
while data_list:
    minimum = data_list[0]
    for x in data_list: 
        if x < minimum:
            minimum = x
    new_list.append(minimum)
    data_list.remove(minimum)
    print (new_list)
def Huhu(data_list):
  ev_li = ''
    od_li = ''
    for i in data_list: 
        if (i % 2 == 0): 
            ev_li.append(i) 
        else: 
            od_li.append(i)
    print(new_list,od_li "startOF->evens",ev_li) 

Thanks for the response I've done

data_list = [3,2,1,4,5,6,7,8,9,22,25,16,17,28]
new_list = []

while data_list:
    minimum = data_list[0]  # arbitrary number in list 
    for x in data_list: 
        if x < minimum:
            minimum = x
    new_list.append(minimum)
    data_list.remove(minimum)
odds = []
evens = []
for i in new_list:
    if i % 2 == 0:
        evens.append(i)
    else:
        odds.append(i)
print(odds,"startOF->evens", evens)

Answer 1

You can use sorted with a custom key argument to sort by.

>>> sorted(listOfNumbers, key=lambda i: (i%2==0, i))
[1, 3, 5, 7, 9, 17, 25, 2, 4, 6, 8, 16, 22, 28]

In this case you can first sort by odd/even, then by the value itself.

Answer 2

If you want to know why you code fails:

data_list = [3,2,1,4,5,6,7,8,9,22,25,16,17,28]
new_list = []
while data_list:
    minimum = data_list[0]
    for x in data_list: 
        if x < minimum:
            minimum = x
    new_list.append(minimum)
    data_list.remove(minimum)
    print (new_list)
def Huhu(data_list):
    ev_li = list()
    od_li = list()
    for i in data_list: 
        if (i % 2 == 0): 
            ev_li.append(i) 
        else: 
            od_li.append(i)
    print(new_list,od_li, "startOF->evens",ev_li) 

You have three errors:

First: indentation problem:

def Huhu(data_list):
  ev_li = ''
    od_li = '' <- Here

Second: a comma is missed here:

print(new_list,od_li [here] "startOF->evens",ev_li) 

Third:

ev_li and od_li must be list

But for sure @CoryKramer is cleaner:P
