What two books has the author edited that were published in 2008 and 2010? Who was the co-editor on the 2008 book?

question:Write a function in Python that takes a string `s` and a number `k` as arguments and returns a new string that consists of the characters of `s` with all occurrences of its first `k` characters removed. For example, if `s = Hello World` and `k = 3`, the function should return `lo World`. ```python def remove_first_k(s: str, k: int) -> str: Removes the first k characters of string s. # Your code goes here ```

question:What does the term upscale mean?

question:What type of restaurant is known as a bistro?
