服工—集合

第一题:

A = {21,234,-32,3,-55}

print(A)

print(max(A))

print(min(A))

第二题:

a,b = map(int,input().split())

count = 0

for i in range(a,b+1):

    if i%3==0 and i%5==0 and i%7==0:

        count+=1

print(count)

第三题:

s = input()

data = {'a','e','i','o','u'}

count = 0

for i in s:

    if i in data:

        count+=1

print(count)

第四题:

a = {'1','2','3','4','5'}

b = {'6','7','8','9','10'}

data = set(input().split(','))

c = data-a

result1 = b-data

result2 = {int(i) for i in result1}

print(*sorted(result2))

思考:'10'字符的位置!!!

第五题:

import random

x,n = map(int,input().split())

random.seed(x)

count = 0

for i in range(n):

    s = []

    for j in range(23):

        s.append(random.randint(1,365))

    for j in s:

        if s.count(j)>1:

            count+=1

            break

print('rate={:.2f}'.format(count/n))

第六题:

l = []

while True:

    s = input().split()

    if s != ['!!!!!']:

        l.extend(s)

    else:

        break

l1 = list(set(l))

print(len(l1))

temp = sorted(l1)

temp = temp[:10]

print('\n'.join(temp))

思考:input().split()→是列表???    

第七题:

n = int(input())

true = 0

false = 0

for i in range(n):

    s1 = input().split()

    s2 = set(s1)

    if len(s1) == len(s2):

        false+=1

    else:

        true+=1

print('True={}, False={}'.format(true,false))

第八题:

s = list(input())

s1 = set(s)

count = 1

for i in s:

    if i in s1:

        print(i,end='')

        s1.remove(i)

        count+=1

    if count ==11:

        break

思考:去除重复,保持原来的顺序

第九题:

stua = set(input().split())

stub = set(input().split())

math = set(input().split())

it = set(input().split())

stua.update(stub)

print('Total: {}, num: {}'.format(sorted(stua),len(stua)))

print('Math and jsj: {}, num: {}'.format(sorted(math&it),len(math&it)))

girl = {i for i in stua if i.isalpha()}

girl = girl & (math | it)

print('FeMale in race: {}, num: {}'.format(sorted(girl),len(girl)))

onlyMath = math – it

print('Only Math: {}'.format(sorted(onlyMath),len(onlyMath)))
