实验3-控制语句与组合数据类型应用

task1-1

x=list(range(10))
print('整数输出1：',end='')
for i in x:
    print(i,end=' ')

print('\n整数输出2:',end='')
for i in x:
    print(f'{i:02d}',end='-')

print('\n整数输出3:',end='')
for i in x[:-1]:
    print(f'{i:02d}',end='-')
print(f'{x[-1]:02d}')

print('\n字符输出1:',end='')
y1=[str(i) for i in range(10)]
print('-'.join(y1))

print('字符输出2:',end='')
y2=[str(i).zfill(2) for i in range(10)]
print('-'.join(y2))




task1-2

print('整数列表:')
x=list(range(97,97+26))
for i in x:
    print(i,end=' ')

print('\n字符列表1:')
lower_alpha=[chr(i) for i in range(97,97+26)]
for i in lower_alpha:
    print(i,end=' ')

print('\n字符列表2:')
upper_alpha=[i.upper() for i in lower_alpha]
for i in upper_alpha:
    print(i,end=' ')



task1-3

import random
import string
print('用列表存储随机整数:')
ls=[random.randint(1,100) for i in range(5)]
print(ls)

print('\n用集合存储随机整数:')
s={random.randint(1,100) for i in range(5)}
print(s)

print('\n\n字母串:',end='')
alpha=string.ascii_letters
print(alpha)
print(type(alpha))

print('\n数字串:',end='')
digits=string.digits
print(digits)
print(type(digits))




task1-00

import random
print('用集合存储随机整数:')
while True:
    s={random.randint(1,100) for i in range(5)}
    print(s)
    if len(s)<5:
        break

 

1. random.randint(1,100) 生成的随机整数范围是？是否包括100？

1-99  不包括 

2. 使用集合解析形式 s = {random.randint(1,100) for i in range(5)} 生成集合， len(s)一定是5吗？

不一定

 

m = 0
n = 1
i=n
y=2
print(f"{m:>10} {n:>10}",end=" ")
while i<=1000:
    m,n=n,i
    print(f"{i:>10}",end=" ")
    i=m+n
    y +=1
    if y %5==0:
      print(end="\n")

 

import random
n=random.randint(1,31)
m=1
while m<3:
    print('猜猜2021年5月哪一天会是你的lucky day')
    x=eval(input('你有三次机会，猜吧(1~31):'))
    if x==n:
        print('lucky day')
        break
    elif x>n:
        print('猜晚啦，你的lucky day在前面，前面')
        x=eval(input('再猜猜：'))
        m+=1
    elif x<n:
        print('猜早啦，你的lucky day还早呢')
        x=eval(input('再猜猜：'))
        m+=1
while m>3:
    print('次数用完啦')
    print('2021年5月你的luky day是'+n+'号')

 

x,n= eval(input('输入十进制整数x和要转换的进制n:'))
m = []
p = []
while x//n!=0 :
    b = x//n
    a = x%n
    x = b
    m.append(a)
    p.append(b)
m.append(b)
l = m[::-1]
for i in l:
    print(i,end='')
