How to drop records with special characters in a dataframe

I am trying to drop records/ Rows in a dataframe with special characters. I have tried many things like:

df1['Day'] = df1['Day'].str.replace(r"[\"\'\|\?\=\.\@\#\*\,]", '')
df.drop(df[df.ID.str.contains(r'[^0-9a-zA-Z]')].index

But i am getting the following recurssion error.

Also, is there any way to impute the records with special characters with mean/median/mode

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from.
