Working with strings

String Python logo

What does Python consider a string?

In short, anything between single, double and triple quotes.

The following give the same output.


                        print('Hello World')
                        print("Hello World")
                    

                        Hello World
                        Hello World

Methods

A method is a function that can be called on a data type to perform a specific task.

Basic String Methods

Python has the following methods to change the case of strings.

  • Title Case: Capitalizes the first letter in each word. 
    .title()
    
                                    my_name = "eRiDanI ALCAntar"
                                    print(my_name)
                                    print(my_name.title())
                                
                                        
                                        eRiDanI ALCAntar
                                        Eridani Alcantar
  • Upper Case: Capitalizes every letter in the string. 
    .upper()
    
                                    my_name = "eridani Alcantar"
                                    print(my_name)
                                    print(my_name.upper())
                                
                                        
                                        eridani Alcantar
                                        ERIDANI ALCANTAR
  • Lower Case: Uses lowercase for every letter in the string. 
    .lower()
    
                                    message = "HELLO WORLD"
                                    print(message)
                                    print(message.lower())
                                
    
                                    HELLO WORLD
                                    hello world
  • Right Strip: Strips the whitespace at the end of the string. 
    .rstrip()
    
                                    message = "HELLO WORLD    "
                                    print(message)
                                    print(message.rstrip())
                                
     
                                    HELLO WORLD____
                                    HELLO WORLD
