I have saved the following panda file into CSV now how do I get it back as a panda file(dataframe) in another program.And is it possible to get single element from the dataframe like for example I want the element of 10th row 3rd column specifically like how it can be done in numpy
df = af.merge(df, on='DateTime', how='left').interpolate()
print(df)
df.to_csv("my_csvfilename.csv")
I get the output
DateTime pop

Others have suggested how to extract specific elements above but retrieving the file in the first place should be as simple as
import pandas as pd
df=pd.read_csv("my_csvfilename.csv")
If you aren't in the same directory you may need to amend to be
df=pd.read_csv(r"C:\directory\my_csvfilename.csv")
But obviously you need the correct path to the directory (eg C:\\My folder\\My subfolder)
