Certification: Basic Level Accuracy: 78.72% Submissions: 141 Points: 5

Write a Python program that converts a string to a list of its individual characters.

Example 1
    
  
  • Input: "Python"
    • 
  
  • Output: ['P', 'y', 't', 'h', 'o', 'n']
    • 
  
  • Explanation: 
    
      
      
    • Step 1: Take the input string "Python".
      • 
      
    • Step 2: Convert each character to an element in a list.
      • 
      
    • Step 3: Return the resulting list ['P', 'y', 't', 'h', 'o', 'n'].
      • 
    
    
  
    •
Example 2
    
  
  • Input: "Hello, World!"
    • 
  
  • Output: ['H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!']
    • 
  
  • Explanation: 
    
      
      
    • Step 1: Take the input string "Hello, World!".
      • 
      
    • Step 2: Convert each character, including spaces and special characters, to an element in a list.
      • 
      
    • Step 3: Return the resulting list ['H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!'].
      •

Constraints
    
  
  • 0 ≤ len(string) ≤ 10^6
    • 
  
  • String contains printable ASCII characters
    • 
  
  • Time Complexity: O(n), where n is the length of the string
    • 
  
  • Space Complexity: O(n)

  • Use list() constructor: list(string)
    •  
  
  • Use list comprehension: [char for char in string]
    •  
  
  • Use for loop: chars = []; for char in string: chars.append(char)
    •  
  
  • Handle empty string case: [] if not string else list(string)
    •

The following are the steps to convert a string to a list of characters:

    

  •  Take a string as input.  

  •  Use `list(string)` to convert it into a list.  

  •  Print the list of characters.  

  •  Handle empty strings correctly.
