Removing Prefix from column of names in python

I have this dataset

ID      Name     
101    DR. ADAM SMITH
102    BEN DAVIS
103    MRS. ASHELY JOHNSON
104    DR. CATHY JONES 
105    JOHN DOE SMITH

Desired Output

ID        Name 
101     ADAM SMITH
102     BEN DAVIS
103     ASHELY JOHNSON
104     CATHY JONES
105     JOHN DOE SMITH 

I need to get rid of the prefix I tried df['Name'] = df['Name'].replace(to_replace = 'DR. ', value = '')I repeated the same code for all prefixes, but I have when I do it nothing happens. Any reason for this?

Thank you in advance.

>Solution :

Use a regular expression to match the first word if it ends with ..

df['Name'] = df['Name'].str.replace(r'^[A-Z]+\.\s+', '', regex=True)
