五个基本函数算法

准备阶段

from functools import reduce
from collections import Iterable
test=list(range(11))
isinstance(test,Iterable)

max()

def max_count(l:list) -> int:
max_num=l[0]
for i in l:
    if max_num < i:
        max_num=i
return max_num

min()

def min_count(l:list) -> int:
min_num=l[0]
for i in l:
    if min_num > i:
        min_num=i
return min_num

sum()

def sum_count(l:list) -> int:
sum_num=0
for i in l:
    sum_num+=i
return sum_num

count()

def count_len(l:list) -> int:
len_num=0
for i in l:
    len_num+=1
return len_num

avg()

def ave_count(l:list) -> int:
sum_num=0
for i in l:
    sum_num+=i
return sum_num/count_len(l)
