Python循环003（小白初学，请勿喷）

循环

死循环：

whlie 1==1：
　　print（“OK”）　　

    1、使用while循环输入 1 2 3 4 5 6     8 9 10
     n = 1
     while n < 11:
      if n == 7:
       pass
      else:
       print(n)
      n = n + 1
     
     print('----end----')
     
    2、求1-100的所有数的和
     n = 1
     s = 0
     while n < 101:
      s = s + n      
      n = n + 1
     
     print(s)
    
    3、输出 1-100 内的所有奇数
     
     n = 1
     while n < 101:
      temp = n % 2
      if temp == 0:
       pass
      else:
       print(n)
      n = n + 1
     
     print('----end----')
      
    4、输出 1-100 内的所有偶数
    
     n = 1
     while n < 101:
      temp = n % 2
      if temp == 0:
       print(n)
      else:
       pass
      n = n + 1
     
     print('----end----')

    5、求1-2+3-4+5 ... 99的所有数的和
     n = 1
     s = 0 # s是之前所有数的总和
     while n < 100:
      temp = n % 2
      if temp == 0:
       s = s - n 
      else:
       s = s + n      
      n = n + 1
     
     print(s)
