但也要努力有诗和远方

在这里做学习记录是不是不大好hahah

python－准备开发环境
mac上预装了2.7.10基本是足够了，在终端执行
# python //可以进入python，并且会直接显示版本号并且交互程序运行
Python 2.7.10 (default, Oct 23 2015, 19:19:21)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>print "hello world"
hello world
>>>exit() //这是退出python的命令
咳咳，避免不了的第一个helloworld.py
# echo print \"Hello world\">helloworld.py
# chmod 777 helloword.py
# python helloworld.py
hello world

当然了，先看语法呗
变量的知识
>>> number=12 //定义一个整形变量
>>> string=abc //定义一个字符型变量－－－不能忘记双引号啊
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'abc' is not defined
>>> string="abc"
>>> print "the number is" +number+ "the name is" +string //打印出来－－－报错了
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
>>> type(number)
<type 'int'>
>>> type(string) －－－变量类型不一样，不能print
<type 'str'>
>>> print "the number is" +number+ "the name is" +int(string) //将字符型转换成整形－－报错了，不能这么转换
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
>>> print "the number is" +str(number)+ "the name is" +string //将整形转换成字符型 －－可以
the number is12the name isabc
>>> print "the number is " +str(number)+ " the name is " +string // 让他展示的漂亮点
the number is 12 the name is abc

决定了，晚上再继续

list
>>> list1=[21] //定义一个list
>>> list1.append(32) //向list里加数据
>>> list1.append(29)
>>> list1.append(2)
>>> print list1
[21, 32, 29, 2]
>>> list1.sort() //给list排序
>>> print list1
[2, 21, 29, 32]
>>> poo=list1.index(32) //查找元素32，得到元素的位置的值
>>> print poo
3
>>> list1.remove(29) //移除元素29
>>> print list1
[2, 21, 32]
>>> leng=len(list1) //查看list的长度
>>> print leng
3
>>>

关于条件选择
>>> if("FreeFloat Ftp Server (Version 1.00)" in an): //接上面的，当语句没结束时用:
... print "[+] FreeFloat FTP Server is vulnerable" //⚠️要有空格在print前，不然交互器就不能换行了，一般时候用\换行也行
... else:
... print "[-] FTP Server is not vulnerable"
...
[-] FTP Server is not vulnerable //因为socket还要再研究下ip和port所以只能返回这种结果了

异常处理
>>> try:
... print "[+] 12/0 = "+str(1337/0) //➗0错
... except Exception,error: //将Exception的内容放到error里面
... print "[-] ERROR ="+str(error) //打印报错
...
[-] ERROR =integer division or modulo by zero
>>> import socket
>>> socket.setdefaulttimeout(2) //设置超时时间
>>> s=socket.socket()
>>> try:
... s.connect(("192.168.95.149",21))
... except Exception,error:
... print "[-] Error : "+str(error)
...
[-] Error : timed out

函数－－－找了个编辑器sublime
import socket
def retBanner(ip,port): //函数
try:
socket.setdeffaulttimeout(2)
s=socket.socket()
s.connect((ip,port))
banner = s.recv(1024)
return bunner
except:
return
def main(): //main
ip1 = 'http://www.sina.com.cn'
ip2 = '192.168.95.149'
port1 = 80
port2 = 21
banner1 = retBanner(ip1,påort1)
print "[+]" + str(ip1) + ": " + str(banner1)
banner2 = retBanner(ip2,port2)
print "[+]" + str(ip2) + ": " + str(banner2)
if __name__ == '__main__':
main()
-------//在终端执行
# python hello.py
[+]http://www.sina.com.cn: None
[+]192.168.95.149: None

迭代哟 －－还是用sublime赞
def checkname(name):
if("king" in name):
print "hi,"+name+",you are king Fimily"
else:
print "i'm sorry,"+name+",you make an error"
return
def checkage(age):
if(age==24):
print "hi,24 girl"
else:
print "i'm sorry,you are "+str(age)+",you make an error"
return
def main():
namelist = ['king3','king2','rong']
agelist = [24,20,24]
for x in range(len(namelist)): //迭代在此！！
checkname(namelist[x])
checkage(agelist[x])
if __name__ == '__main__': //主函数在此
main()

# python for.py
hi,king3,you are king Fimily
hi,24 girl
hi,king2,you are king Fimily
i'm sorry,you are 20,you make an error
i'm sorry,rong,you make an error
hi,24 girl
//这是运行结果，运行三次，判断家族和年龄

python模块sys
使用sublime
import sys //加载模块
if len(sys.argv)==2: //长度＝2 即sys.argv[0],sys.argv[1]这两个元素其中sys.argv[0]元素师python脚本名称
filename = sys.argv[1] //将第二个参数赋予变量filename
print "[+] Reading Vulnerabilities from : "+filename
# python syss.py names.txt
[+] Reading Vulnerabilities from : names.txtå
