Complete the tasks below. Please turn in a single Jupyter notebook named 4_first_last.ipynb (substitute your first and last name). Please run Kernel > Restart & Run All on your notebook before turning in.

1. Create a list of 10 random integers in the range of -100 to 100.
2. Loop through that list using a for loop. Put the non-negative (positive or zero) integers into a new list. If negative integers are encountered, print a message saying that the value is negative and printing that value.

1. Write a function that does what you did in part A but with the following differences:
   • The input list can be any list of numbers.
   • The function should take as a parameter a threshold for being included in the new list (e.g., if you want non-negative integers, the threshold would be 0, and the function would check if values are >= to this value).
   • The printed message for failing to be included should also report the threshold parameter.
   • The new list should be returned by the function.
2. Execute the function on your list of 10 random integers.

1. Create a two-dimensional list with 3 'rows' and 4 'columns' and a mixture of strings and integers.
2. Loop through each element of the list and check if each element is a string or an integer. Save the strings as a dictionary with the index (row, column) as the key and the string as the value. Save the integers as a dictionary with the index (row, column) as the key and the integer as the value.
3. Print out your dictionaries (no print command required).

1. Create a list of 5 strings that are first and last names, e.g. 'Jon Doe'.
2. Use a list comprehension (a single-line command) to get the first initial from each name and store each string (e.g. 'J') in a new list. Print this list (no print command required).
3. Repeat but store both the first and last initial (e.g. 'JD') in a new list. Print this list (no print command required).
4. Save this second list to a text file.

1. Download this text file of past World Series winners.
2. Read in the lines of the file to a list, so that each line is an element of the list.
3. Create a new list with just those list elements that contain 'New York'; print that list, making sure there's not an extra newline character between each line. Print this list (no print command required).
4. Use the set class to convert the list of all World Series winners to a list of unique values. Print this list (no print command required).
5. Write the output to a new file.
