Python字典练习【第九周】

六、金币排列

在这里插入图片描述

n=eval(input())
a=[]
j,k=-1,-1
cnt,res=0,0
for i in range(1,n):
    a.append(i)
while True:
    j+=1
    cnt=a[j]+cnt
    if(cnt>=n):
        break
if(sum(a[:3])==n):
    print(j+1,a[0])
else:
    m=cnt-n
    while True:
        k+=1
        res=a[k]+res
        if(res>=m):
            break
    p=res-m
    if(p==0):
        print(j-k,a[k+1])
    else:
        print(j-k+1,p)

七、歌咏小能手

在这里插入图片描述

n=eval(input())
a= list(map(int,input().split(",")))

a.remove(max(a))
a.remove(min(a))

sum = 0
for i in a:
    sum += i
ave = float(sum/(n-2))
cnt = 0
for i in a:
    if i<ave:
        cnt+=1
print("此人最终得分是:{:.3f},有{:d}个低于平均值的成绩。".format(ave, cnt))

八、矩阵相加

在这里插入图片描述

n=int(input())
a=[]
for i in range(n):
    s1=input()
    a.append([int(n) for n in s1.split()])

b=[]
for i in range(n):
    s2=input()
    b.append([int(n) for n in s2.split()])

for i in range(n):
    for j in range(n):
        t=a[i][j] + b[i][j]
        if(j==n-1):
            print("{:^3d}".format(t),end="  ")
        else:
            print("{:^3d}".format(t), end="  ")

    print(end="\n")

九、寻找最佳组合

在这里插入图片描述

n = eval(input())
s = list(map(int,input().split(",")))

a = []

for i in range(len(s)):
    t = []
    if s[i]==9:
        t.append(s[i])
        a.append(t)
for i in range(len(s)):
    t = []
    flag = 0
    for j in range(i+1,len(s)):
        if s[i]+s[j]==9 and s[i]!=0 and s[j]!=0:
            flag=1
            t.append(s[i])
            t.append(s[j])
    if flag == 1:
        a.append(t)

for i in range(len(s)):
    for j in range(i+1,len(s)):
        t = []
        flag = 0
        for k in range(j+1,len(s)):
            if s[i]+s[j]+s[k]==9 and s[i]!=9 and s[j]!=9 and s[k]!=9:
                flag = 1
                t.append(s[i])
                t.append(s[j])
                t.append(s[k])
        if flag==1:
            a.append(t)

print(a)

十、单词的区域

在这里插入图片描述

s = list(input().split())

re = ['q','w','e','a','s','d','z','x','c','Q','W','E','A','S','D','Z','X','C']
bl = ['r','t','y','f','g','h','v','b','n','R','T','Y','F','G','H','V','B','N']
ye =['u','i','o','p','j','k','l','m','U','I','O','P','J','K','L','M']


words={}
pre=[]
for i in s:
    cnt=0
    for j in i:
        if j in re:
            cnt +=1
    if cnt== len(i):
        pre.append(i)
pbl=[]
for i in s:
    cnt=0
    for j in i:
        if j in bl:
            cnt +=1
    if cnt== len(i):
        pbl.append(i)

pye=[]
for i in s:
    cnt=0
    for j in i:
        if j in ye:
            cnt +=1
    if cnt== len(i):
        pye.append(i)
words['Red'] = pre
words['Blue'] = pbl
words['Yellow'] = pye

print(words)
