Pandas: replace function syntax

Question

I have a huge DataFrame with a column that has a list of names. Names have numbers and brackets attached to them. I try to remove them from their names. I found that a method that will work for this:

df.Name = df.Name.str.replace(r'[\(\)\d]+', '')

Can someone help me understand the syntax inside the replacement function?

(r'[\(\)\d]+', '')

In this regular expression, means a group of characters . Here the group of characters is filled in (open bracket), (closing bracket) and (numbers). [...]\(\)\d
