Use “matplotlib.pyplot.plot" to produce a plot of the functions f(x) = x * e(-x/10) and g(x) = e-x/10) * cos(pi * x)

In Python write out the Python Code for the following in Jupiter Lab. Show code and outputs. Use a data set and build 3 different pivot tables that each have a least a different index row or column. (You cannot build 2 pivot tables that have the same index rows and columns but aggregate differently. You also cannot simply flip the index rows and columns.) For each pivot table, build a graph.

Question is in the photo attached Need a simple python code that does not involve the map() function

Write the code in python to define the function has_adjacent_repeats(mystr), which takes a string parameter and returns a boolean result.   - If mystr has at least one instance of adjacent characters being equal, return True   - Otherwise, return False Hint: You can iterate over the positive indices i for characters in mystr: 1, 2, 3, ...., len(mystr)-1 with a for loop. For each i, if the character at index i matches the character at index i - 1, return True. Otherwise, if no doubled character is found in the entire string, return False. For example: Test Result if not (has_adjacent_repeats("NOODLES") is True): print("error")   if not (has_adjacent_repeats("Bananas") is False): print("shwoopsie")   if not (has_adjacent_repeats("Hanoverr") is True): print("error")
