代码如下:
# -*- coding: utf-8 -*- #!/usr/bin/python # filename: todo.py # codedtime: 2014-8-28 20:50:44 import sqlite3 import bottle @bottle.route('/help3') def help(): return bottle.static_file('help.html', root='.') #静态文件 @bottle.route('/json:json#[0-9]+#') def show_json(json): conn = sqlite3.connect('todo.db') c = conn.cursor() c.execute("SELECT task FROM todo WHERE id LIKE ?", (json)) result = c.fetchall() c.close() if not result: return {'task':'This item number does not exist!'} else: return {'Task': result[0]} #返回Json对象 bottle.debug(True) bottle.run(host='127.0.0.1', port=8080, reloader = True)
第一个路由@bottle.route('/help3') 返回一个静态问,在浏览器中输入:http://127.0.0.1:8080/help3
结果如下:
其中的 root='.')或 root='./')表示在程序当前目录下,当然你也可以知道其他的路径如: root='/path/to/file'
第二个路由@bottle.route('/json:json#[0-9]+#')返回一个Json对象,在浏览器中输入:http://127.0.0.1:8080/json4
结果如下:
Web程序难免会遇到访问失败的错误,那么怎样去捕获这些错误,Bottle可以用路由机制来捕捉错误,如下捕获403、404:
@error(403) def mistake403(code): return 'The parameter you passed has the wrong format!' @error(404) def mistake404(code): return 'Sorry, this page does not exist!'
其他错误处理如法泡制!

Python is not strictly line-by-line execution, but is optimized and conditional execution based on the interpreter mechanism. The interpreter converts the code to bytecode, executed by the PVM, and may precompile constant expressions or optimize loops. Understanding these mechanisms helps optimize code and improve efficiency.

There are many methods to connect two lists in Python: 1. Use operators, which are simple but inefficient in large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use the = operator, which is both efficient and readable; 4. Use itertools.chain function, which is memory efficient but requires additional import; 5. Use list parsing, which is elegant but may be too complex. The selection method should be based on the code context and requirements.

There are many ways to merge Python lists: 1. Use operators, which are simple but not memory efficient for large lists; 2. Use extend method, which is efficient but will modify the original list; 3. Use itertools.chain, which is suitable for large data sets; 4. Use * operator, merge small to medium-sized lists in one line of code; 5. Use numpy.concatenate, which is suitable for large data sets and scenarios with high performance requirements; 6. Use append method, which is suitable for small lists but is inefficient. When selecting a method, you need to consider the list size and application scenarios.

In Python, a for loop is used to traverse iterable objects, and a while loop is used to perform operations repeatedly when the condition is satisfied. 1) For loop example: traverse the list and print the elements. 2) While loop example: guess the number game until you guess it right. Mastering cycle principles and optimization techniques can improve code efficiency and reliability.

To concatenate a list into a string, using the join() method in Python is the best choice. 1) Use the join() method to concatenate the list elements into a string, such as ''.join(my_list). 2) For a list containing numbers, convert map(str, numbers) into a string before concatenating. 3) You can use generator expressions for complex formatting, such as ','.join(f'({fruit})'forfruitinfruits). 4) When processing mixed data types, use map(str, mixed_list) to ensure that all elements can be converted into strings. 5) For large lists, use ''.join(large_li

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
