I have a column named Value in my jeopardy data frame. I am giving the column here
I want to remove the '$' and the ',' symbols and also convert the whole column into a float dtype. I used the following code:
jeopardy['Value'].replace(regex=True, inplace=True, to_replace=r'[$,]', value=r'')
jeopardy['Value'] = jeopardy['Value'].astype(float)
which gave me the following error:
ValueError: could not convert string to float: 'None'
I even tried this
jeopardy['Value'] = pd.to_numeric(jeopardy['Value'],errors='coerce')
which converts the whole column values into Nan.
I want to convert the whole jeopardy['Value']
column into a float dtype by removing the '$' and ','
I think you need espace $
because special regex character and pass to to_numeric
:
jeopardy['Value'] = pd.to_numeric(jeopardy['Value'].replace('[\$,]', '',regex=True),
errors='coerce')
