1、 A set of achievements 67,90,-20,105,88,92, Please change the negative score to 0, exceed 100 Of is set to 100, Then the output .

# 1、 A set of achievements 67,90,-20,105,88,92, Please change the negative score to 0, exceed 100 Of is set to 100, Then the output .
from typing import List

lst = [67, 90, -20, 105, 88, 92]
for i in range(len(lst)):
    if lst[i]<0:
        lst[i]=0
    elif lst[i]>100:
        lst[i]=100
print(lst)

2、 Input 5 Results of students , Descending output , And find the average score

# 2、 Input 5 Results of students , Descending output , And find the average score 
a = (input(" Please enter the scores of five students ："))
a1 = a.split(',')
lst1 = list(a1)
print(lst1)
lst1.sort(reverse=True)
print(lst1)
print(len(lst1))
sum = 0
for i in range(0, len(lst1)):
    sum += int(lst1[i])
print(" Average score :" + str(sum / len(lst1)))
--------------------------------------
lst2=[]
for i in range(5):
    score=int(input(" Please enter the grade ："))
    lst2.append(score)
    sum+=score
lst2.sort(reverse=True)
print(lst2)
print(f' The average is {
      sum/5}')

3、 Determine whether a sequence is orderly

lst3 = [12, 12,12,12,12]
if  lst3==sorted(lst3):
    print(' yes ')
elif lst3==sorted(lst3,reverse=False):
    print(' yes ')
else:
    print(' no ')
