    "In this case study we'll walk through using Python to fetch some data, clean it, and then graph it. This may be a short project, but it combines a number of features of the language we've dicussed, and gives you a chance to a see a project worked through from beginning to end. At almost every step we will also briefly call out alternatives and enhancements you can make.\n",

    "Global temperature change is the topic of much discussion. But those discussions are based on a global scale, Suppose I want to know what the temperatures have been doing near where I am? One way of finding out would be to get some historical data for my location and process that data and plot it to see exactly what's been happening. \n",

We're going to talk through using data from the Global Historical Climatology Network, which has data from around the world. You may find other sources, which may have different data formats, but the steps and the processes we discuss here should be generally applicable to any data set. "

As mentioned earlier, we can disregard the flags for this exercise. We can also see that missing values for the temperatures are coded with -9999 if the that day is not in the month, so for a typical February, for example, the 29th, 30th, and 31st values would be -9999. \n",

We need to split the line into its separate fields abd we need to ignore or discard the flags for each daily value.  We also need toremove the values with -9999, convert the year and month into ints and the temperature values into floats, keeping in mind that the temperature readings are in tenths of degrees centigrade. Finally we need to calculate the average value as well as picking out the high and low values. \n",

One would be to do several passes over the data, splitting into fields, discarding the placeholders, converting strings to numbers, and finally calculating the summary values. Or we can write a function that performs all of these operatons on a single line, and do everything in one pass. Both can be valid approaches, and in this case we'll take the latter approach and create a function `parse_line` do perform all of our data transformations."
