Activity 04: Expressions and Datatypes

Solve the following problems.

See https://asu-compmethodsphysics-phy494.github.io/ASU-PHY494/2021/01/28/04_Python_1/ for help.

Temperature conversion

Create a program tempconverter.py that asks the user to input a temperature in degree Fahrenheit (θ) and prints the temperature in Kelvin (T), according to the equation

      5
  T = - (θ - 32) + 273.15
      9

Your program should assign the temperature in Kelvin to a variable T.

List indexing and slicing

Given the lists

 letters = ['A', 'B', 'C', 'D', 'E', 'F']
 temperatures = [60.1, 78.3, 98.8, 97.1, 101.3, 110.0] 

create a program slices.py that assigns to variables a, b, ... the following:

• a: extract the letter 'E' from letters
• b: extract the letters 'C', 'D' from letters
• c: extract the letters 'D', 'E' from letters (hint: use negative indices)
• d: find the length of temperatures
• e: extract the second-but last value from temperatures
• f: extract the last two values from temperatures
• g: reverse the order of temperatures (note the step argument of slicing!)

List construction

Given an empty list stuff in a file stuff.py, perform the following steps and print stuff.

1. append "dog"
2. append "mouse"
3. replace element 1 with 42
4. extend with list [-1.234, "cat", [3, 2, 1]]

Now

1. copy stuff to a list more_stuff
2. replace elements 1 and 2 with the list ['python', 'swallow']
3. remove the last element and extend with the list ['Hund', 'Python', 'Schwalbe', 'Katze']
4. insert at position 2 the list ['parrot', 'llama']
