問題編寫一個程序，輸入主字符串，然后通過在每個字符后嵌入基于短符號的字符串來創建加密字符串。該程序還應該能夠從加密字符串生成解密字符串。代碼def encrypt(string,key):    return key.join(string)def decrypt(string,key):    return key.split(string)#mainoriginal_str=input("Enter a string:")encrypt_key=input("Enter encryption key:")encrypt_str=encrypt(original_str,encrypt_key)print("The encrypted string:",encrypt_str)decrypt_str=decrypt(encrypt_str,encrypt_key)decrypted_str=" ".join(decrypt_str)print("The decrypted string:",decrypted_str)輸出Enter a string:twinkle twinkle little starEnter encryption key:*The encrypted string: t*w*i*n*k*l*e* *t*w*i*n*k*l*e* *l*i*t*t*l*e* *s*t*a*rThe decrypted string: *問題我希望解密字符串的輸出為：twinkle twinkle little star而不是 *
