This article mainly introduces in detail the relevant information about the method of storing dictionaries in python3-list. Friends in need can refer to it
# Auther: Aaron Fan #示例1: #定义几个字典 alien_0 = {"color":"green", "points":5} alien_1 = {"color":"yellow", "points":10} alien_2 = {"color":"red", "points":15} #把字典存入到列表aliens中 aliens = [alien_0, alien_1, alien_2] #遍历这个列表 for alien in aliens: print(alien) #示例2: #创建一个用于存储外星人的空列表 aliens = [] #创建30个绿色的外星人 for alien_number in range(30): new_alien = {"color":"green", 'points':5, 'speed':'slow'} aliens.append(new_alien) #显示前5个外星人 for alien in aliens[:5]: print(alien) print("...") #显示一共创建了多少个外星人 print("外星人的数量是: %d" % len(aliens)) #示例3: #创建一个用于存储外星人的空列表 aliens = [] #创建30个绿色的外星人 for alien_number in range(30): new_alien = {"color":"green", 'points':5, 'speed':'slow'} aliens.append(new_alien) for alien in aliens[0:3]: if alien['color'] == 'green': alien['color'] = 'yellow' alien['speed'] = 'medium' alien['points'] = 10 elif alien['color'] == 'yellow': alien['color'] = 'red' alien['speed'] = 'fast' alien['points'] = 15 #显示前5个外星人 for alien in aliens[:5]: print(alien) print("...")

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

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.
