Python一键FTP传文件

Posted on 2009/06/09 by 枯藤昏鸦

每天下班前都需要将工作文档上传到FTP服务器，得写好文档后再打开FTP软件->登录->找到要传的文件->上传->关闭软件。久了难免会不烦，反正文档名和上传位置是固定不变，还是把Python拿出来发挥一下它的神威吧。

Project Euler Python解题汇总 005 ~ 010

Posted on 2009/06/04 by 枯藤昏鸦

What is Project Euler?
Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.

这些解基本上都是用Python暴力解出来的，没有经过优化，只求答案不起速度，但是为了知道运算在什么位置了还加了一些额外的附加代码的，哇咔咔。

问题5:
What is the smallest number divisible by each of the numbers 1 to 20?
求1,2,..,19,20的最小公倍数。

i=2520
while(True):
    flag=True
    for j in range(11,21):
        if i%j<>0:
            flag=False
        #else:
        #    print i,j
    if flag:
        print i
        break
    i=i+2520
    if i%1000000==0:
        print "now is",i

i=2520

while(True):

flag=True

for j in range(11,21):

if i%j<>0:

flag=False

#else:

# print i,j

if flag:

print i

break

i=i+2520

if i%1000000==0:

print "now is",i

问题6:
Find the difference between the sum of the squares of the first one hundred natural numbers and the square of the sum.
求1至100和的平方与1至100的平方和之差。

a = 0
b = 0
for i in range(1,101):
    a=a+i*i
    b=b+i
print b*b-a

a = 0

b = 0

for i in range(1,101):

a=a+i*i

b=b+i

print b*b-a

问题7:
Find the 10001st prime.
求第10001个素数（质数）。

            flag = False
            break
    return flag
 
t=0  
for i in count(2):
    if ispre(i):
        t+=1
    if t>10000:
        print i
        break

break

return flag

t=0

for i in count(2):

编码解决GAE导致CSS失效问题

这个问题不是GAE导致的，CSS文件和模板文件编码不一致导致的，转换成一致的编码，或者设置一下link文件的charset。

语法高亮工具Pygments

Posted on 2009/04/27 by 枯藤昏鸦

天天写代码，天天看代码，没有颜色的代码看久了自然会眼花，于是各种高亮工具诞生了。基本上每个IDE都集成了代码语法高亮着色器，在Web应用里面，代码着色可以在用户端用JavaScript实现也可以在服务器端实现，PHP实现的着色工具最多，可惜俺不会，找啊找啊找到了这款神奇的代码语法着色器Pygments，支持很多语言（有一多半语言我都只听说过），俺够用了，而且是Python写的，方便偶在GAE里面折腾。
官方地址：http://pygments.org/

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, wikis or other applications that need to prettify source code.

在GAE中使用reCAPTCHA

Posted on 2009/04/26 by 枯藤昏鸦

Google App Engine是好东东，容易实现一些基于Web的小想法；reCAPTCHA也是好东西，大家都一起来防SPAM。而我就这么一点小乐趣，东搞搞西搞搞。
在GAE上面使用reCAPTCHA也很容易，并且已经有人写出来了具体怎么做，偶也依样画葫芦写了个演示，没有什么实际的功能，纯属瞎折腾看看自己验证码输对了没。
