python - Drop values after train test split

Question

May i know how do i drop values in y_train that correspond to x_train after splitting data?

For example: I want to drop those values in y_train that are NaN for X_train['Current_ratio']

X_train['Current_ratio'] = X_train[X_train['Current_ratio'].notnull()]
y_train ???

Answer 1

You can do:

 X_train = X_train.dropna(subset=['Current_ratio'])
 y_train = y_train.dropna()

You better do that before splitting though
