In this Data analysis with Python and Pandas tutorial, we’re going to clear some of the Pandas basics. Data prior to being loaded into a Pandas Dataframe can take multiple forms, but generally it needs to be a dataset that can form to rows and columns.

    Great Video. I’m having a little trouble with an error:
    module ‘pandas’ has no attribute ‘DataFrame’

    This is what I have so far:

    import pandas as pd

    web_stats= {xxxxxxxx}

    df = pd.DataFrame (web_stats)

    What am I doing wrong?

    Doing great!. Really good one. Just one thing I want to ask what other attributes, functions and members of pandas besides the ones you’ve taught in the series should I go through to get a handle more complex data sets. I mean if only you can give me a blunt list, Ill be glad.

    # df.set_index(‘day’, inplace=True)

    hi,if i type the above df2=df.set_index("day",inplace=True) ,i will get the error like AttributeError: ‘NoneType’ object has no attribute ‘head’
    but if i type df.set_index(‘day’, inplace=True) , it will be fine.

    can you tell me why?

    When I hit F5, my Python module closes immediately after running. How do I prevent that? Currently, I’m just using "import os os.system(‘pause’)

    I noticed that after you used df.set_index(‘Day’, inplace=True) the day index only goes to 5 instead of 6, how can that be fixed? I added one more entry to all three entry’s and it still only goes to 5, what’s up????

    Hello, first of all let me tell you , you explain terrific! I have a great doubt. I’m very new to this topics and I’m being asked to retrieve information from txt files and from that calculate TF-IDF, Boolean matrix, term document matrix, similitude measures (cosine, etc) and plot all that. I chose python because I was told it has several tools which make it easy, do you have any material or cookbook for that? Or maybe a guide? Thanks!!!

    when you print a single column from a data frame you have set with an index, would it not return the column along with the index? great video btw!

    in the new python version you have to install pandas-datareader
    pip install pandas-datareader.

    #import pandas-datareader as web
    import pandas_datareader as pdr

    if you use that it will work.

    This doesn’t show anything using terminal or an IDE, but when I run the code in Ipython, I can see my plot. This is pretty annoying. I also don’t like Ipythonย btw. Pycharm is great!

    Is there an easy way to distinguish or identify commands that modify the dataframe or don’t modify it by default rather than printing or checking every time?
    Also I loved the video, thanks!

    Hi, you "import matplotlib.pyplt as plt" then you have "from matplotlib import style". When do you start with "import" and "from". Sorry if it is a naive question but could not get a good answer just googling.

    i have python 3.5 .but this test = pd.DataFrame(web_stats)
    doesn’t work with me. why?

  42. Nishant Porwal April 26, 2017 at 10:15 pm - Reply

    hi i have been successfully runned the code as it was described my question is the code runs TRUE for both these statements
    1. df.set_index(‘Day’, inplace=True)
    2. df.set_index(‘Day’, inplace=’True’)
    in 1. we have true without any apostrophes while in second one we have True as a string by use of apostrophes

  45. Christopher Forte April 26, 2017 at 10:16 pm - Reply

    Instead of using a second line to set the index to ‘Day’ would it be good practice to do it from the start with:

    df = pd.DataFrame(web_stats).set_index(‘Day’)

    Or is it generally a better idea to separate it out as you did? Thanks, you have some great videos

    I am using python3.6, this doesn’t work I think. It gives a bunch of errors in the modules

    You shoud try in ipython:

    $ %run <file name>

    It would bring you some confort.

    when i key print(df[[‘Visitors’,’Bounce Rate’]]). It shows KeyError: "[‘Bounce Rate’] not in index". I am using python 2.7. May I know what might be the reason caused this?
