The home_ppg_per_odds_pre_game and away_ppg_per_odds_pre_game are basically the same metric. The former reprsents the value of this metric for the home_team, while the latter represents this metric for the away team. I want a mean of this metric for each team and that is regardless whether the team is playing home or away. In the example df you Manchester United as home_team_name in zero and as away_team_name in 5. I want the mean for Manchester United that includes all this examples.
df.groupby("home_team_name")["home_ppg_per_odds_pre_game"].mean()
This will only bring me the mean for the occasion when the team is playing home, but I want both home and away.
Since the two metrics are the same, you can append the home and away team metrics, like this:
data_df = pd.concat([df.loc[:,('home_team_name','home_ppg_per_odds_pre_game')], df.loc[:,('away_team_name','away_ppg_per_odds_pre_game')].rename(columns={'away_team_name':'home_team_name','away_ppg_per_odds_pre_game':'home_ppg_per_odds_pre_game'})])
Then you can use groupby to get the means:
data_df.groupby('home_team_name')['home_ppg_per_odds_pre_game'].mean().reset_index()

I need to change 0 level index ('Product Group') of pandas groupby object, based on conditions (sum of related values in column 'Sales').
Since code is very long and some files are needed, I`ll copy output.
the last string of code is:
tdk_regions = tdk[['Region', 'Sales', 'Product Group']].groupby(['Product Group', 'Region']).sum()
###The output will be like this
Product Group Region Sales

Data set screenshot:
I have a data set which looks like the picture above. It has multiple (unique) observations for the same Movie Name. For example, there are 3 unique observations for the movie Aan Milo Sajna and 2 for Aap Ke Saath.
I want that wherever there are multiple observations for a given Movie Name, they get collapsed into a single observation such that each variable value is the mean of the multiple observations.
For example, see below.
Transformed data set screenshot:
The Movie Names that had single observations remain untouched. But the three observations for Aan Milo Sajna and the 2 observations for Aap Ke Sath get collapsed into single observations. And each of the variable values is changed to the mean of the multiple observations as shown in the picture.
How can I accomplish this?
df_mean = df.groupby('MOVIE NAME').agg(np.mean).reset_index()

Been trying to search for this but somehow can't seem to find the right answer.
Given the following simple dataframe:
country continent population
0 UK Europe 111111
1 Spain Europe 222222
2 Malaysia Asia 333333
3 USA America 444444
How can I retrieve the country value if I have a condition WHERE an index value is given? For example, If I am given an index value of 2, I should return Malaysia.
Edit: Forget to mention that the input index value comes from a variable (think of it as a user select a particular row and the selected row provide an index value variable).
Thank you.
df.iloc[2]['country']
iloc is used for selection by position, see pandas.DataFrame.iloc documentation for further options.
index = 2
print(df.iloc[index]['country'])
Malaysia
The values come from a Junit test case or from a scanner, so the method has to work in all scenarios. The array List looks something like this.
Utah 5
Nevada 6
California 12
Oregon 8
Utah 9
California 10
Nevada 4
Nevada 4
Oregon 17
California 6
I need to be able to calculate the average of, let's say, Utah. I know how to do something that finds the average. My biggest problem is knowing how to only get values from the names of Utah rather than just getting all of them.
names=states values= numbers categories=what
you are calculating
here is the start of the method:
public static ArrayList<Double> summarizeData (ArrayList<String> names, ArrayList<Double> values ,ArrayList<String> categories, int operation)
I have a dataset whose entries has 5 different attributes and one value. For example, I have a height of 5000 people. For each person I have his hair color, eye color, his nationality, the city he were born and the name of his mother (the 5 dimensions).
No/Eye Color/Hair Color/Nationality/Hometown/Mother's Name/Height
Blue Blond Swiss Zürich Nicole 184
Blue Brown English York Ruby 164
Brown Brown French Paris Sophie 154
etc..
So there are 5 dimensions. The data is set dynamically, so the number of categories in each dimensions can vary. I sought to compute the average height of people depending on whether I want to include some dimensions or not (from 1 to 5). For example I wanted the retrieve:
The average height of French and Blue eyed people. Next day only the people born in London. And the week after, the Swiss, blue-eyed, red-haired, born in Geneva and whose mother is called Nicole.
So I create a pivot table with the Eye Color as Row labels, Hair Color as Column labels, the average height as the Data and the last 3 dimensions as Market Filters. This allowed me see all the possible and desired combinations of average height that my data implies.
Now my goal is:
I want to create a Macro that goes through all the possible combinations that my dimensions entails (i.e 2^5-1=31) and store in a vector all the combination of height average that are above a certain value, e.g. 190. And then It could print on a worksheet.
I was thinking on using some booleans arrays vector and For-Each-Next structure, but I must say that I fail to picture how to implement it.
Any ideas?
Thanks for the time and help!
