[英]How to remove characters from a specific place in a string(not by index) in Python
所以我有這個代碼:
def myprogram():
import string
import random
import getpass
inputpasswd = getpass.getpass("Password: ")
passwd = ("I<3StackOverflow")
if passwd == inputpasswd:
qwerty = input("Type something: ")
def add_str(lst):
_letters = ("1","2","3","4","5","6","7","8","9","0","q","w","e","r","t","z","u","i","o","p","a","s","d","f","g","h","j","k","l","y","x","c","v","b","n","m","!","#","$","%","&","/","(",")","=","?","*","+","_","-",";"," ")
return [''.join(random.sample(set(_letters), 1)) + letter + ''.join(random.sample(set(_letters), 1))for letter in lst]
print(''.join(add_str(qwerty)))
input("")
else:
print("Wrong password")
input("")
我的問題是:我如何制作一個相反的程序,所以它接受了一堆垃圾字母並將其轉換為有意義的文本?
示例:如果我在此程序中鍵入類似“aaaaaaa”的內容,則會將其轉換為“mapma&”at7ar8a2ga-ka *“
在這個新程序中,我想輸入“mapma&”at7ar8a2ga-ka *“並輸出”aaaaaaa“。
這對你有用嗎?:
s="1a23a45a6"
print(s[1::3]) # aaa
這樣做: initial_str = random_str[1:-1:3]
,其中random_str是帶垃圾的字符串
