学Python的第四天

第四天啦，今天依旧代码少的啃树皮....

但是作业留的有了幼儿园的水准！！！让小编我看到了希望....

#!/usr/bin/env python
# -*- coding:utf8 -*-
import time
count = 0
while count < 10:
    print ("ok",time.time())
    #count = 100
    count = count + 1
print (123)
 
#1.使用while循环输入1 2 3 4 5 6        8 9 10
num = 1
while num <= 10:
    if num == 7:
        pass
        num = num + 1
    else:
        print (num)
        num = num + 1
#2.求1-100相加数之和
num1 = 1
num = 0
while num1 <=100:
    num = num + num1
    num1 = num1 + 1
print (num)
 
#3.输出1-100内所有奇数
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内所有偶数
n = 1
while n < 101:
    temp = n % 2
    if temp == 0:
        print (n)
    else:
        pass
    n = n + 1
 
#5.求1-2+3-4+5...99所有数和
n = 1
s = 0
while n < 100:
    temp = n % 2
    if temp == 0:
        s = s - n
    else:
        s = s + n
    n = n + 1
print (s)
 
#6.用户登录三次机会
number = 1
while number <= 3:
    inp = input ("input password: ")
    if  inp == "":
        print ("OK")
        break
    else:
        print ("EOFError")
        number = number + 1
