 Python & Dataframe basic question
#1
Hey one quick and very easy questions for all of you I am sure haha! Related to pandas & dataframes

So basically I just have to create a dataframe that contains the GDP Data from an already imported panda library. There is a dictionary under the word "links" containing the csv file with the data. The actual question is the following


" The dictionary links contain the CSV files with all the data. The value for the key GDP is the file that contains the GDP data. The value for the key unemployment contains the unemployment data.

In [44]:
[i] links={'GDP':'https://s3-api.us-geo.objectstorage.softlayer.net/cf-courses-data/CognitiveClass/PY0101EN/projects/coursera_project/clean_gdp.csv',\'unemployment':'https://s3-api.us-geo.objectstorage.softlayer.net/cf-courses-data/CognitiveClass/PY0101EN/projects/coursera_project/clean_unemployment.csv'
[/i]


Question 1: Create a dataframe that contains the GDP data and display the first five rows of the dataframe.
Use the dictionary links and the function pd.read_csv to create a Pandas dataframes that contains the GDP data.
Hint: links["GDP"] contains the path or name of the file.


In [52]:[python]links={'GDP':'https://s3-api.us-geo.objectstorage.softlayer.net/cf-courses-data/CognitiveClass/PY0101EN/projects/coursera_project/clean_gdp.csv'}
links_frame=pd.DataFrame(links, index=[0])
path_csv=links
df=pd.read_csv(path_csv)[python]



Writing [52] gives me the following errors:

What am I doing wrong?!! I am sure it is very simple but as I am very new to this I would appreciate your help!!!! Thank you all Smile Smile Smile
