Python - list the content of an algorithm

Dear Experts,

Actually trying to analyze the machine learning logics behind in algorithms, for example the KNeighborsClassifier():

import pandas
from sklearn.neighbors import KNeighborsClassifier
model = KNeighborsClassifier()
print(model)

Select allOpen in new window

Could you please advise would it be possible to list the content of an algorithm in Python and with which syntax concretely? The above print(model) of course just provides some overall information about the algorithm, but not the content

Thanks in advance,
