How to solve FutureWarning: The default value of regex will change from True to False in a future version ?

In a future release, the default value of regex for Series.str.replace() will be changed from True to False. Furthermore, when regex=True is used, single character regular expressions are not processed as literal strings.

use regular expressions explicitly as given below.

dframe['colname'] = dframe['colname'].str.replace(r'\D+', regex=True)

Hope the above solution works.
