Python Basics Exercises: Strings and String Methods (Summary)

In this video course, you’ve reinforced your knowledge of Python string objects. You can now confidently access different characters in a string using indices and slices, and you can determine the length of a string with len().

You also practiced methods. You used .upper() and .lower() to convert all characters of a string to uppercase and lowercase, respectively. With .rstrip(), .lstrip(), and .strip(), you removed whitespace from strings, and you figured out if a string starts or ends with a given substring through .startswith() and .endswith().

You also practiced capturing input from a user as a string using the input() function, and you converted that input to a number using int() and float(). You converted numbers and other objects to strings using str().

Finally, you used the .find() and .replace() methods to find the location of a substring and replace a substring with a new string.
