Price column object to int in pandas

I have a column called amount with holds values that look like this: $3,092.44 when I do dataframe.dtypes() it returns this column as an object how can i convert this column to type int?

in regex \D means not digit... so we can use pd.Series.str.replace

dataframe.amount.replace('\D', '', regex=True).astype(int)

0    309244
1    309244
Name: amount, dtype: int64
