Generating random strings until a given string is generated using Python
Given a string, our task is to generate some strings using the random combination of characters, special characters, numbers etc.
Example
Input PP Output AK AK . . . . .
Algorithm
Step 1: Input a string. Step2: Here we store all possible combination of lowercase, uppercase and special characters in a variable. Step3: Use two loops and use random function. From this, we can get all the possible combinations of characters, symbols. Step4: At the end display same string which is same as an input string and it matches each random string with given input string. Step5: If both index values are same then store the index and iterate for the remaining.
Example code
import string
import random
import time
my_possibleCharacters = string.ascii_lowercase + string.digits + string.ascii_uppercase + ' ., !?;:'
t = "ab"
my_attemptThis = ''.join(random.choice(my_possibleCharacters)
for i in range(len(t)))
my_attemptNext = ''
com = False
iteration = 0
# Iterate while completed is false
while com == False:
print(my_attemptThis)
my_attemptNext = ''
com = True
for i in range(len(t)):
if my_attemptThis[i] != t[i]:
com = False
my_attemptNext += random.choice(my_possibleCharacters)
else:
my_attemptNext += t[i]
# increment the iteration
iteration += 1
my_attemptThis = my_attemptNext
time.sleep(0.1)
# Driver Code
print("String matched after " + str(iteration) + " iterations")Output
