Remove characters from string in a column

Question

I have a column which contains number of months in string and int format. Need to convert it into just integers. (eg 12)

df1=pd.DataFrame({'Term':["12"," ","12 Months","12months","12mthsb","12 *4months"]})

Output:

df1=pd.DataFrame({'Term':["12","12","12","12","12"]})

Tried using str.replace(r'\D', '') and str.replace(r'[^0-9]', '') but then the row with just the number (ie 12) gets replaced by NaN

Answer 1

You probably have int/float/str mix in the column

You can try to convert to str and then replace:

df1['someColumn'].astype(str).str.replace(r'\D', '')
