Pandas error when using resample and groupby to apply function - python

I am new to python. I used to code in R and work with period_apply function. So I tried the following approaches in python below.
First, I do not understand what the errors are trying to tell me.
Second, I do not understand why I only get errors with groupby if I include the first row of the data. Yet with resample, i get error no matter whether I include the first row or not.
Third, how do I resolve this problem, please do not tell me skip the first row, because I work with a much much bigger dataset
Data
Best_Bid Best_Ask
Timestamp
2019-05-02 11:59:59.602 29636.0 29638.0

And I am trying to apply the below function(I know I could have just done .agg({'Best_Bid':['last']}) but this is a simplified version of my original code).
Function
def func(x):
best_bid = (x['Best_Bid'])[-1]
best_ask = (x['Best_Ask'])[-1]
return pd.Series([best_bid,best_ask], index=['bbbid', 'aaask'])
groupby and grouper
If I skip the first row and run. Things work fine.
df.iloc[1:,:].groupby(pd.Grouper(freq='180S',closed='right',label='right',base=-0.0001)).apply(func)
bbbid aaask
Timestamp
2019-05-02 12:59:59.999899904 NaN NaN
However, if i include the first row, I got the following error.
df.groupby(pd.Grouper(freq='180S',closed='right',label='right',base=-0.0001)).apply(func)

KeyError: 'Best_Bid'

From what I can tell you are getting an error with the (x['Best_Bid'])[-1] because it is returning a KeyError: -1
Your apply function is iterating though each element (x) from the column (Best_Bid and Bid_Ask) and trying to grab the last index from the element (x) which doesn't make sense.
I don't have your dataset in front of me to work with but I would try this code to see if it works.
gdf = df.groupby(pd.Grouper(freq='180S',closed='right',label='right',base=-0.0001)).copy()
print(gdf['Best_Bid'][gdf.index[-1]],gdf.index[-1])
print(gdf['Best_Ask'][gdf.index[-1]],gdf.index[-1])
Now this code can definitely be simplified but it should work for all rows and it will be much faster than the .apply method if it is a large dataset.

pandas: code works in pycharm but doesn't work in replit

I'm trying to run this code in replit:
df_cat = pd.melt(df, id_vars='cardio', value_vars=['active', 'alco', 'cholesterol', 'gluc', 'overweight', 'smoke'])
c = df_cat.groupby(['cardio','variable','value'], as_index=False,level=None, sort=True, group_keys=True, observed=False).size()
cardio_0 = c[c['cardio']==0]
cardio_1 = c[c['cardio']==1]
the code works perfectly in pycharm, but it doesn't work in replit and I don't know
what else to do. I got this error:

saving coordinates from Dataframe as Polygons (shapely.geometry) AttributeError

I want to create a Polygon from a list of coordinates:
import pandas as pd
from shapely.geometry import Point, Polygon
data = pd.read_csv('path.csv', sep=';')
the data is in the following format
Suburb

I = data.loc[data['Suburb'] == 1]
I['coordinates'] = list(zip(I['features_geometry_x'], I['features_geometry_y']))

I think the issue here is that you need more than one data point to create a polygon where as your suburb 2 and 3 each got only a single point.

This is not happening in the scala version of spark.

Get the last value of dataframe's column with indexing

I am trying to get the last value of column named "mass".
df = pd.read_csv('0000.csv', names=["chi", "mass"])
df_1 = pd.read_csv('0001.csv', names=['chi', 'mass'])
x=df['mass'][-1]
print(x)
And it raised error:

However, I did succeed for the first value using df['mass'][0]. Why it does not work for index "-1"? I know there are alternative methods like using iloc iat values. But I just think df['mass'][0] would be the simplest one if it works.

from geopandas import GeoSeries
x_data = np.arrange(20)
y_data = np.arrange(20)
Now, I want to have an array of points and later, to create a LineString from a region of that array. Now I have:
points = GeoSeries(map(Point, zip(x_data, y_data)))
My problem is regarding the creation of the LineString. I do:
line = LineString([points[initial:last]])
But this is giving me errors:
Traceback (most recent call last): File
"shapely\speedups\_speedups.pyx", line 86, in
