importing in python packages for future use and renaming with a shorter variable

  • matplotlib.pyplot --> plt
    • keeps track of current figure & plotting area
    • example code:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4], [1,4,9,16], 'ro')
plt.axis([0, 6, 0, 20])
plt.show()

  • pandas --> pd
    • used for ease with labeled data analysis
  • numpy --> np
    • N-dimensional array object
  • collections --> coll
    • lists
    • dictionaries
    • *Indices are integers that start from zero
  • stats
    • allows access to:
      • mean()
      • median()
      • mode()
      • stdev()       (standard deviation)
      • variance()

DataFrame:
csv --> saving the excel spreadsheet as csv makes it comma separated data in rows/columns rather than tabled.
Semantics14/15/16/17 based on year of data
Use pandas package for opening the data
Pulls in four different excel data reports from '14,'15,'16,'17 that are saved under those titles in folder

shape provides dimensions of data

6/14/17 Notes

I want to write a code so that I can search the name of a class, and everyone who took that class will appear. Originally I assumed I could use the same command I did to search for a specific name, and then edit that so the code would search for a specific person. However, looking at the format of the file, there are four different columns that contain class information, while there’s only one column with name information. I am going to see if I can search for a specific class in the “Am S1” column first to see if everything runs smoothly, and if that works, I will look for ways to search for an ID word in multiple columns. I tried this command. Only the column headings are appearing and nothing else Studentinfo14[Studentinfo14['Am S1'].str.contains('Discovery', na=False)] I changed “Studentinfo14” to attendance so that the code would look for this information in the attendance file instead of the master file. This worked, but using this file means that I ca...

6/06/17 Notes (formatting code and searching for a specific person)

Working on fixing the format of the code, deleting cells, and making sure everything in an organized order to make it easier to use Earlier I was having a problem displaying the Confidence survey chart so I renamed all the columns and then it displayed. I now found that the command “ConfidenceS#.lock[:,:] also works, and is much more efficient because now I don’t have to go through each survey and copy and past the column names for every year of every survey. This works for all of them except Semantics, not sure why. I finished adding all the survey information I needed to merge all the surveys for 2014. I keep getting errors in the cells that deal with inverting numbered responses because certain column headers “don’t exist.” This means I actually will have to rename all the columns. However, for some reason this does not affect the cells that merge all the data. I successfully uploaded all the files onto the code and merged all the surveys and the attendance spreadsheet to...
