Error-"'Column' object is not callable".

hv — Thu, 30 Mar 2023 16:43:07 GMT

I am trying to lowercase one of the columns(A_description) of a dataframe(df) and getting the error-"'Column' object is not callable".

Code: def new_desc():

for line in df:

line = df['A_description'].map(str.lower)

return line

new_desc()

Have used the following methods:

.str.lower()

.apply(str.lower)

.apply(lambda x: x.lower())

.map(str.lower)

All gave the same error.
