I have a data set that I need to reformat so that I can plot and work with it further. It is sort of an transpose action but I am struggling to not overwrite the data in the new dataframe. I sorted out the headings using dictionaries and it maps the fields from the original df to the new output df correctly. It is just overwriting the first entry and not adding a new POLY/POLY_NAME
Input dataframe:
Output dataframe:
Below is my code so far:
import pandas as pd
fractions = {"A": 1.35, "B": 1.40, "C": 1.45}
quality = {"POLY_NAME":"POLY", "AS":"Ash", "CV":"CV","FC":"FC","MS":"Moist","TS":"Tots","VM":"Vols","YL":"Yield"}
frac = list(fractions.values())
headers = list(quality.values())
df = pd.DataFrame(columns=headers, index=frac)

I resolved to duplicate/overwriting of the values by first grouping the original wash DF and then in the for loop and the data of each loop into a blank DF and at the end of the loop append it to the Final DF. Just for neatness I made the index column a normal column and reordered the columns.
groups = wash.groupby("POLY_NAME")
df_final = pd.DataFrame(columns=headers)
for name, group in groups:
df = pd.DataFrame(columns=headers)
for label, content in group.items():
if quality.get(label[-2:]) in headers:
#print(label)
#print(name)
#print(label, content)
for c in content:
try:
df.loc[fractions.get(label[0]), "POLY"] = name
df.loc[fractions.get(label[0]), quality.get(label[-2:])] = c
#print('Poly:', name, ' fraction:', fractions.get(label[0]), ' quality:', quality.get(label[-2:]))
except:
pass
df_final = df_final.append(df)
df_final = df_final.reset_index().rename({'index':'FLOAT'}, axis = 'columns')
df_final = df_final.reindex(columns=["POLY","FLOAT","Ash","CV","FC","Moist","Tots","Vols","Yield"])
Might not be the neatest or fastest method but it gives the required results.

Here is the code I am using:
df['C'] = np.where((df['spread'] > 60) & (df['volume'] > df['Ma_mult_high']),'green','red')
fig = go.Figure()
# add OHLC trace
fig.add_trace(go.Candlestick(x=df.index,
open=df['open'],
high=df['high'],
low=df['low'],
close=df['close'],
showlegend=False))
# add moving average traces
fig.add_trace(go.Scatter(x=df.index,
y=df['ma'],
opacity=0.7,
line=dict(color='blue', width=2),
name='MA 5'))
fig.add_trace(go.Scatter(
x = df.index,
y = df['close'],
mode = 'markers',
marker_color=df.C
))
fig.update_layout(xaxis_rangeslider_visible=False).show()`
the output
in the image, you can see that plot both True and false signal, maybe because the marker_color = "C" but if change that and use only color names it will plot noting even if i change the y = df['close'], i get the same problem

It seems to me that the issue is in your np.where() statement, likely with the nan values in Ma_multi_high producing the false statement in df['volume'] > df['Ma_mult_high'] that result in 'red'.
Try this:
df['C'] = np.where((df['spread'] > 60) & (df['volume'] > df['Ma_mult_high'].fillna(0)),'green','red')
I am trying to pass into a url a date in the format 2015-12-20, search the pandas dataframe and do a model.predict on it.
The problem is that I am trying to convert a working code from the jupyter lab into the .py file in order to run everything on the flask server and following I can not transfer.
The following code only works if the 'Date' column is converted to datetime. If it is in object format, the following code also doesn't work.
data.loc[2015-12-06]
The above works but the following gives an error:
data.loc['2015-12-06']
KeyError: '2015-12-06'
How do I pass in the 2015-12-06 not as string for the .loc to work?
print(data.head(5).to_dict())

What is the most pythonic way to drop the rows in df2 where col1 and col2 and col3 and col4 (and coln for that matter) have the same values as the respective columns of df1?
I don't want to merge the dataframes, only drop any rows in df2 (might be multiple) where the row tuple over the interest columns is the same in both dfs.
I have only come up with how to do this using :
new_df = df2.loc[df2[col1].isin(df1[col1]) &
df2[col2].isin(df1[col2]) &
df2[col3].isin(df1[col3]) &
df2[col4].isin(df1[col4]) &
df2[col5].isin(df1[col5]) ]
which is a bit cumbersome for larger datasets and for more columns.
Any ideas for a better way?
You can using isin,before doing that we need create a key using all value from col1~ coln(convert to str and paste together)
df2[~df2[df1.columns].astype(str).sum(1).isin(df1.astype(str).sum(1))]
You can use set_index combined with pd.Index.difference to extract your result:
idx = df2.set_index(list(df2)).index\
.difference(df1.set_index(list(df1)).index)
res = df2.set_index(list(df2)).loc[idx].reset_index()
The benefit of this method is it doesn't require numeric to string conversion.
Currently attempting to create a function where I divide columns in my DataFrame called DF_1 and group them by a dimension column in the same DataFrame.
The below code is attempting to achieve this by first grouping by the dimension column and applying a lambda function to each of the columns that I am trying to divide in order to get the average of each of the metrics i.e. cost per conversions, or cost per click.
Unfortunately, I am unsure how to accomplish this. The below code gives an error of TypeError: lambda() takes 2 positional arguments but 3 were given
calc_1 = DF_1[['Conversions_10D', 'Total_Revenue', 'Total_Revenue', 'Clicks', 'Spend']]
calc_2 = DF_1[['Impressions', 'Spend', 'Conversions_10D', 'Impressions', 'Clicks' ]]
def agg_avg(df, group_field, list_a, list_b):
grouped = df.groupby(group_field, as_index = False).apply(lambda x, y: x/y, list_a, list_b)
grouped = pd.DataFrame(grouped).reset_index(drop = True)
return grouped
