1.使用while循环输入1 2 3 4 5 6 8 9 10
1 count = 0 2 while count < 10: 3 count = count + 1 4 if count == 7: 5 print(" ",end = "") 6 continue 7 else: 8 print(count,end = " ")
2.求1 - 100的所有的数的和
1 count = 1 2 sum = 0 3 while count <= 100: 4 sum += count 5 count = count + 1 6 print(sum)
3.输出1 - 100的所有的奇数
1 count = 1 2 row = 0 3 while count <= 100: 4 if count % 2 == 1: 5 row = row + 1 6 print("%2d"%(count),end = "") 7 if row % 10 == 0: 8 print() 9 else: 10 print(" ",end = "") 11 count = count + 1
4.输出1 - 100 的所有的偶数
1 count = 1 2 row = 0 3 while count <= 100: 4 if count % 2 == 0: 5 row = row + 1 6 print("%2d"%(count),end = "") 7 if row % 10 == 0: 8 print() 9 else: 10 print(" ",end = "") 11 count = count + 1
5.求1+2+3+4+5...99的所有数的和
1 count = 1 2 sum = 0 3 while count <= 99: 4 sum += count 5 count = count + 1 6 print(sum)
6.用户登录(三次重试机会)
1 times = 1 2 username = input("Please input your username:") 3 while times <= 3: 4 if username == "John": 5 print("Welcome Back!",end = "") 6 break 7 else: 8 if times % 3 != 0: 9 print("Wrong input!") 10 else: 11 print("Please check out your username after 5 minutes!",end = "") 12 break 13 times = times + 1 14 username = input("Please input your username:")

---无人问津也好，技不如人也罢，你都要试着安静下来，去做自己该做的事，而不是让内心的烦躁、焦虑，坏掉你本来就不多的热情和定力
