In the -introduction to Python lesson we wrote a function that reads these files -but it’s stuck off in an IPython notebook. We could copy and paste it -into a new notebook every time we want to use it but that gets tedious -and makes it difficult to add features to the function. The ideal -solution would be to keep the function in one spot and use it over and -over again from many different places. Python modules to the rescue! - -We’re going to move beyond the IPython notebook. Most Python code is -stored in \`.py\` files and then used in other \`.py\` files where it -has been pulled in using an \`import\` statement. Today we’ll show you -how to do that. - -## Exercises - -### Exercise 1 - -Make a new text file called \`animals.py\`. Copy the file reading -function from yesterday’s IPython notebook into the file and modify it -so that it returns the columns of the file as lists (instead of printing -certain lines). - -### Exercise 2 - -We’re going to make a function to calculate the mean of all the values -in a list, but we’re going to write the tests for it first. Make a new -text file called \`test\_animals.py\`. Make a function called -\`test\_mean\` that runs your theoretical mean function through several -tests. - -### Exercise 3 - -Write the mean function in \`animals.py\` and verify that it passes your -tests. - -### Exercise 4 - -Write tests for a function that will take a file name and animal name as -arguments, and return the average number of animals per sighting. - -### Exercise 5 - -Write a function that takes a file name and animal name and returns the -average number of animals per sighting. Make sure it passes your tests. -- 2.26.2
