For instance, [None, 'hello', 10] doesn’t sort because integers can’t be compared to strings and None can’t be compared to other types. 2. 00:17 So, what are data types? Write a python program to read three numbers and if any two variables are equal , print that number. For instance the dog_name variable holds a string : 'Freddie' . Python is a general-purpose programming language that is becoming ever more popular for data science. e.g. 3. Include a method distanceTo() that computes distances using the great-circle distance (see the Great circle exercise in Section 1.2). Recall that unlike R, Python has only one way to assign values, by using the = sign. One of the most effective ways of learning or improving programming skills is by solving coding tasks. 5. In each exercise, there is a Python script that contains some data, and some instructions for what to do with that data.
