df. dropna( how= 'all' )
remove nan particular column pandas
df= df. dropna( subset= [ 'columnname] )
how to filter out all NaN values in pandas df

pandas drop rows with nan in a particular column
In [ 30 ] : df. dropna( subset= [ 1 ] )

pandas remove nan, inf
df[ ~ df. isin( [ np. nan, np. inf, - np. inf] ) . any ( 1 ) ]
when converting from dataframe to list delete nan values
a = [ [ y for y in x if pd. notna( y) ] for x in df. values. tolist( ) ]
print ( a)
[ [ 'str' , 'aad' , 'asd' ] , [ 'ddd' ] , [ 'xyz' , 'abc' ] , [ 'btc' , 'trz' , 'abd' ] ]
