Whitespace characters include spaces, tabs, and newlines.

1. Using replace() Method:
   • Replaces spaces with an empty string.
2. Code Example:
   
   Copy Code Copied Use a different Browser

   
   my_string = "Hello   world!  How are you?   "
   no_spaces = my_string.replace(" ", "")
   print(no_spaces)  # Output: "Helloworld!Howareyou?"
   

   
   
3. Using List Comprehension:
   • Removes all whitespace characters, not just spaces.
4. Alternative Code:
   
   Copy Code Copied Use a different Browser

   
   my_string = "Hello   world!  How\tare you?\n"
   no_whitespace = ''.join([c for c in my_string if c != ' ' and c != '\t' and c != '\n'])
   print(no_whitespace)  # Output: "Helloworld!Howareyou?"
   

   
   
5. Using the translate() Method:
   • More efficient and comprehensive way.
6. Another Approach:
   
   Copy Code Copied Use a different Browser

   
   import string
   
   my_string = "Hello   world!  How\tare you?\n"
   translation_table = str.maketrans('', '', string.whitespace)
   no_whitespace = my_string.translate(translation_table)
   print(no_whitespace)  # Output: "Helloworld!Howareyou?"
   

   
   
7. Explanation:
   • The translate() method is more efficient and removes all whitespace characters in a single call.
