Python 中带有不常用字符的连接字符串？

这里给出了两个字符串，首先我们必须从第一个字符串中删除所有常见元素，并且第二个字符串的不常用字符必须与第一个字符串的不常用元素连接。

示例

Input >> first string::AABCD
Second string:: MNAABP
Output >> CDMNP

算法

Uncommonstring(s1,s2)
/* s1 and s2 are two string */
Step 1: Convert both string into set st1 and st2.
Step 2: use the intersection of two sets and get common characters.
Step 3: now separate out characters in each string which are not common in both string.
Step 4: join each character without space to get a final string.

示例代码

# Concatination of two uncommon strings 
def uncommonstring(s1, s2):
# convert both strings into set
   st1 = set(s1)
   st2 = set(s2)
   # take intersection of two sets to get list of common characters 
   lst = list(st1 & st2)
   finallist = [i for i in s1 if i not in lst] + \ [i for i in s2 if i not in lst]
   print("CONCATENATED STRING IS :::", ''.join(finallist))
# Driver program
if __name__ == "__main__":
   s1 =input("Enter the String ::")
   s2=input("Enter the String ::")
   uncommonstring(s1,s2)

输出

Enter the String ::abcde
Enter the String ::bdkl
CONCATEATED STRINGIS ::: acekl
