Im trying to find a way to compare what students performed consistantly in their InternalAssessment_Performance to their FinalExam_Performance. Essentially i need to find what students have the same answer in both those columns.
How is it possible to compare the values in both commons and have them returned if they are the same?
Any help no matter how small would be great.
If the columns are aligned you can do something like this:
df[df['InternalAssessment_Performance'] == df['FinalExam_Performance']]

import pandas as pd
Data = pd.open_csv('file name')
Data = isnull().sum()
I know that here we are testing each cell if it were empty or not; then, return the summation of empty ones.
Is there any other ways to re-write the statement?
Can we store the True results in a data structure, add them using a loop, and return the result?

If two list is having same number, then the final list should not have the number
If your lists contains unique elements, consider using sets instead.
https://docs.python.org/2/library/sets.html
Check this code:
ls=[1,2,3,4,5,5]
ls1=[1,2,3,4,5,7,8,9]
common_elements=set(ls).intersection(set(ls1))
for i in common_elements:
if ls.__contains__(i):
ls.remove(i)
if ls1.__contains__(i):
ls1.remove(i)
final_ls=ls+ls1
print(final_ls)

I want to convert an image of a graph (plot) to corresponding data. Is there any python library to do this or maybe some sample code to learn from?
If not, then how do i approach this problem?
You can also use a digitizing software application, to convert graph images to data, that is to numbers. im2graph is free and available for both Linux and Windows. See http://www.im2graph.co.il.
