I have the following dataframe column

>>> df2['Age]1    25
2    35
3    48 y
4    34 yea
5    29
...

I just want to keep the number en replace the value in df2['Age] like that

1    25
2    35
3    48
4    34
5    29
...

My code doesn't work :

df2.Age.replace('^.*','^[0-9]*[0-9]',regex=True,inplace=True)

here's the result

 1    ^[0-9]*[0-9]2    ^[0-9]*[0-9]3    ^[0-9]*[0-9]4    ^[0-9]*[0-9]5    ^[0-9]*[0-9]...

Thanks for any help in advance

Use \D+ for replace non numeric to empty string:

df2.Age.replace('\D+','',regex=True,inplace=True)
print (df2)Age
1  25
2  35
3  48
4  34
5  29
