Python: Create two strings from a given string

Last update on December 21 2024 07:46:54 (UTC/GMT +8 hours)

Separate single and multiple occurrence chars.

Write a Python program to generate two strings from a given string. For the first string, use the characters that occur only once, and for the second, use the characters that occur multiple times in the said string.

Visual Presentation:

Sample Solution:

Python Code:

# Import Counter from collections
from collections import Counter

# Function to generate two strings 
def generateStrings(input):

  # Create a character counter from input
  str_char_ctr = Counter(input) 
  
  # Part 1 contains single occurrence characters
  part1 = [key for (key,count) in str_char_ctr.items() if count==1]
  
  # Part 2 contains multiple occurrence characters
  part2 = [key for (key,count) in str_char_ctr.items() if count>1]

  # Sort the characters in each part
  part1.sort()
  part2.sort()

  return part1,part2

# Test input string  
input = "aabbcceffgh"

# Generate the two strings
s1, s2 = generateStrings(input)

# Print first string  
print(''.join(s1))

# Print second string
print(''.join(s2)) 

Sample Output:

egh
abcf
