Question:ciphered text : HESL{LRAT5PN51010T_CNPH1R}3
Try decrypting:
files: [script.py](script.py)text = 'flag{...}'
key = [3,1,2]
li0 = []li1 = []li2 = []for i in range(0,len(text)):    if i % 3 == 0:        li0.append(text[i])    elif (i - 1) % 3 == 0:        li1.append(text[i])    elif (i - 2) % 3 == 0:        li2.append(text[i])li = []for i in range(len(li1)):     li.append(li1[i])     li.append(li2[i])    li.append(li0[i])
# print(li)print("The ciphered text is :")ciphered_txt = (''.join(li))print(ciphered_txt)
- looks like another substitution cihper, this time changing the shift based on the key and then appending them in  order of %1, %2, %0- also looks like the key is listed as "3, 1, 2"1) to reverse it:2) lets just open the script and change the for loop to be ``` for i in range(len(li1)):     li.append(li2[i])     li.append(li0[i])    li.append(li1[i])```and`text = HESL{LRAT5PN51010T_CNPH1R}3`3) run script.pyThe ciphered text is :SHELL{TRAN5P051T10N_C1PH3R}**flag: SHELL{TRAN5P051T10N_C1PH3R}**
