options to show all statistics available. Print this. 4. Clean the data a. Check for missing data values. Is the isna() with sum() method to identify missing cells. The result should look like this year o state o month o number 0 date o dtype: int64 b. The goal is to generate a bar chart with a count of the number of fires per month. Since there are months with 0 fires, you can eliminate these values from the data set. First, use the replace function to replace Os with NaN values (Not a Number). Use the np.nan value as the replacement value. Do a print of the head() of the data to now see NaN values. c. To remove the lines, use the dropna() function. This function looks for NaN values in a specific column. Research how to specify a column as the input parameter. Use the "number" column. 5. Group the data a. The goal in this step is to create a pandas series to be used in the chart. The data must be transformed so that there are totals by month. Research the pandas groupby() function syntax. The goal is to specify the number column as a list key and then sum() function to get the totals. Assign the results of the groupby0 function to a new variable which is the data series. b. Use the print() command for the variable in (a). This should show you totals for each month- in alphabetical order.
