I read in a csv like this
df = pd.read_csv(self.file_path, dtype=str)
then I try this:
df = df[df["MY_COLUMN"].apply(lambda x: x.isnumeric())]
I get an AttributeError:
AttributeError: 'float' object has no attribute 'isnumeric'
Why is this happening? The column contains mostly digits.
I want to filter out the ones where there are no digits.
This question is not how to achieve that or do it better but why do I get an AttributeError
here?
Why is this happening?
I think because NaN is not converting to string
if use dtype=str
, still is missing value, so type=float
Use Series.str.isnumeric
for working isnumeric
with missing values like all text functions in pandas:
df[df["MY_COLUMN"].str.isnumeric()]
