Not able to display add labels to existing data - python

I am trying to execute this cell in jupyter but the following error is thrown tried different methods to solve but no use
This is the line that throws error:
data['label'] = data['label'].apply(lambda x:labelling(x))

trying to do regression analysis so that i can define predictors

Housing_df = Housing_df.iloc[0:22000]
predictors = ['bedrooms','bathrooms','sqft_living','sqft_lot','floors','waterfront','view','condition','yr_built','sqft_above','sqft_basement','yr_built','zipcode']
outcome = 'Price'
I'm getting an error on the Outcome however if I run the same code on a different file it runs prefectly

I am trying to predict the price of housing based on some predictors which I would want from the regression analysis or correlation
However, when I am trying to split the data the above mentioned error shows up

why do I get the keyerror exception?

here's the part of my code in googlecolab where I get the error :
arguments = {'Epoch':6000, 'LearningRate':0.005}
SoftmaxRegression = Multinomial_Regression(X_train,y_train,arguments)
SoftmaxRegression.fit(X_train,y_train)

I can't subset rows in pandas this way: df[0] (or with any integer)

I loaded a csv and then tried to get the first row with the row index number
import pandas as pd
pkm = pd.read_csv('datasets/pokemon_data.csv')
pkm[0]
But for some reason I get this error, as far as I know, you can subset the way I did.

When I use .iloc or .loc I don't face any issues
I used pandas 1.1.5 and 1.2.0 and I got the same error
This is how the data looks:
pokemon_data

pkm[0] calls for the column named 0 in pkm. That's why it's not working.
Try pkm['HP'] or using a column name and it will be clear.
