给定字符串,任务是使用特殊字符、数字和字母的随机组合生成相同的字符串。
null
例如:
Input : GFG Output :n4W mK7 k1x q;;, !g . . . . . GF, GFf GFp GFG Target matched after 167 iterations
先决条件: 在Python中生成随机Id
string.ascii_lowercase
, string.digits
, string.ascii_uppercase
是Python中字符串模块中的一些常见字符串常量,在这里用作字典。所有这些字符串常量都与其他特殊字符组合在一起,比如 ‘ ., !?;:’ 并存储在变量中。
方法: 只需运行两个循环,并使用python提供的随机函数。它将显示随机函数可以提供的所有可能的组合,同样的事情也将由解密循环完成。最后,它将显示提示输入时插入的文本。它会将每个随机字符串与给定字符串匹配。如果两个索引都匹配,则修复该索引并迭代剩余的索引。 以下是实施情况:
# Python program to generate and match # the string from all random strings # of same length # Importing string, random # and time modules import string import random import time # all possible characters including # lowercase, uppercase and special symbols possibleCharacters = string.ascii_lowercase + string.digits + string.ascii_uppercase + ' ., !?;:' # string to be generated t = "geek" # To take input from user # t = input(str("Enter your target text: ")) attemptThis = ''.join(random.choice(possibleCharacters) for i in range ( len (t))) attemptNext = '' completed = False iteration = 0 # Iterate while completed is false while completed = = False : print (attemptThis) attemptNext = '' completed = True # Fix the index if matches with # the strings to be generated for i in range ( len (t)): if attemptThis[i] ! = t[i]: completed = False attemptNext + = random.choice(possibleCharacters) else : attemptNext + = t[i] # increment the iteration iteration + = 1 attemptThis = attemptNext time.sleep( 0.1 ) # Driver Code print ( "Target matched after " + str (iteration) + " iterations" ) |
输出:
FyFJ .:YZ aubo . . . g56G gk6R g7Se gT o gD d gXek g0ek g ek . . gUek giek geek Target matched after 168 iterations
