Given the string, the task is to generate the same string using the random combination of special character, numbers, and alphabets.
Examples :
Input : GFG
Output :n4W

Prerequisite : Generating random Id’s in Python
string.ascii_lowercase, string.digits, string.ascii_uppercase are some of the common string constants present in the string module in Python, which are used here as dictionary. All these string constants are combined with other special characters like ‘ ., !?;:’ and are stored in a variable.
Approach : Simply run two loops and use random function provided by python. It will show all the possible combinations that can be provided by the random function and same thing will be done by the decrypt loop. At the end, it will show the same text as you have inserted when prompted to enter. It will match each random string with the given string. If both index matches then fix that index and iterate for the remaining.
Below is the implementation :
# Python program to generate and match # the string from all random strings# of same length # Importing string, random# and time modulesimport stringimport randomimport time # all possible characters including # lowercase, uppercase and special symbolspossibleCharacters = string.ascii_lowercase + string.digits + string.ascii_uppercase + ' ., !?;:' # string to be generatedt = "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 = Falseiteration = 0 # Iterate while completed is falsewhile 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 Codeprint("Target matched after " + str(iteration) + " iterations") |
