• python-字符串X编码Xformat方法


    1.输出12个星座符号,以反斜线分隔。

    1 print(ord(''))#字符转为编码号
    2 print(oct(8800))#八进制
    3 for i in range(12):
    4     print(chr(9800+i),end='/')#编码号转为字符

    2.恺撒密码的编码

     1 a=ord('a')
     2 s=input('输入你的明文:')
     3 print('密文:',end=' ')
     4 for i in s:   #以我输入的字符串s做一个循环
     5     if ord('a')<=ord(i)<=ord('z'):
     6         
     7         print(chr(a+((ord(i)-a+3)%26)),end='')
     8     elif ord('0')<=ord(i)<=ord('9'):
     9         print(chr(ord('0')+((ord(i)-ord('0')+3)%10)),end='')
    10 
    11     else:
    12               print(i,end=' ')

    3.输入姓名,格式输出:占4位、居中、不足4字的以空格填充。

    1 #{ }里的格式控制 <序号>:<填充><对齐><宽度><千分位><精度><类型>
    3 name=input('输入姓名:')
    4 print('你的名字:{0:' '^4}'.format(name))

         #由于四字居中不明显,所以略微改了一下格式:

    1 name=input('输入姓名:')
    2 print('你的名字:{0:#^16}'.format(name))

    4.格式化输出:中华人民共和国国内生产总值(GDP)689,136.89亿元(2015年)(千分位、2位小数,浮点数)

        #format()的{}以0为起点

    print('中华人民共和国国内生产总值(GDP):{0:,.2f}亿元({1}年)'.format(689136.89,"2015"))

    5.打出99乘法表

    for x in range(1,10):
        for y in range(1,x+1):
            print('{}x{}={}'.format(x,y,x*y),end=' ')
        print('
    ')

    47 When I was 13 I had my first love
    48 There was nobody that compared to my baby
    49 And nobody came between us or could ever come above
    50 She had me going crazy
    51 Oh I was starstruck
    52 She woke me up daily don't need no starbucks
    53 She made my heart pound
    54 Asking for a beat when I see her in the street
    55 And at school on the playground
    56 But I really wanna see her on the weekend
    57 She knows she got me dazy
    58 Cause she was so amazing
    59 And now my heart is breaking
    60 But I'll just keep on saying
    61
