# How Can I Solve it? TypeError: fillna() got an unexpected keyword argument 'implace' [closed]

I am trying to replace NaN values in a given dataset with this

import pandas as pd
import quandl
import math

df.fillna(-9999, implace=True)


But I keep on getting this error:

**

Traceback (most recent call last):

File "regression.py", line 44, in df.fillna(0,implace=True)

File "/home/compname/.local/lib/python3.6/site-packages/pandas/core/frame.py", line 3790, in fillna downcast=downcast, **kwargs)

TypeError: fillna() got an unexpected keyword argument 'implace'
