Question

1)Given a list L1, create a list L2 that contains all but the last element of L1 (e.g. if L1 is ["a","z",True], L2 should be equal to ["a","z"]

2)Given a string s, assign a variable has_z that is True if s contains the letter "z" anywhere within it.

3)Write Python code that calculates the mean of a given list of numbers x and saves the result in a variable m.

4)Given two numeric variables, x and y, assign the maximum of x and y to a variable m.

5)given a string s, write Python code that sets a boolean variable has_two_caps to True if the string contains exactly two capital letters (use the .isupper() string method to test individual letters) and False otherwise.

6)Given two variables x and y containing numerical values and a boolean variable use_x, assign a third variable z the value of x if use_x is True; assign it the value of y if use_x is False.

7)Given a list of logical values x, set all_x to True if all of the values in x are True, and False otherwise
