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.

Hello/Hallo, I really liked this course .. I have questions as some of the solutions did not work for me (but i did not use repl, i used something named replit)
Exercice 4 of Task 1, with \ does not work… This below works :
Also when getting character from s string i thought it was mandatory to write
user_input[0:1]but when I saw that you wrote[0]… Anyway, i realised that you could chain methods and its a must ! Vielen Dank noch einmal!
