Zip function in Python to change to a new character set.

PythonProgrammingServer Side Programming

Given a 26 letter character set, here we are using a new character set. And another character set just like alphabet set (a, b, c........z), then our task is to make a relation between new character set and that alphabet set.

Example

New character set: qwertyuiopasdfghjklzxcvbnm
Input: "wwmm"
Output: bbzy

Algorithm

Step 1: Given a new character set and input the string to make a relation.
Step 2: and the original character set also given below.
Step 3: Create a dictionary, we use here map technique, we map the English character set and new given character set, zip() does it for us. Both character sets are the map, here we match each character of given character set with each character of new charset sequentially.
Step 4: iterate through the original string and get characters of an original character set.
Step 5: join characters without space to get new string.

Example Code

# Function to change string to a new character 
defnewString(cs,n): 
   ori = 'abcdefghijklmnopqrstuvwxyz'
   newchar = dict(zip(cs,ori)) 
   newstr = [newchar[chr] for chr in n]  
   print (''.join(newstr)) 
# Driver program 
if __name__ == "__main__": 
   newcharSet = 'qwertyuiopasdfghjklzxcvbnm'
   input = 'wwmn'
   newString(newcharSet,input) 

Output

bbzy
