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

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
