how to replace null values with 0 in python

#Utilise the fillna function from pandas.DataFrame.
#Note: It will fill na values for every column.
import pandas as pd

df = pd.DataFrame(dict)
#or
df = pd.read_csv("csv_file")

df = df.fillna(0)

#Note: the fillna function comes from the pandas dataframe function.
#For example:

pd.DataFrame(dict).fillna(int)

#Pandas DataFrame function is also a class because it contains functions
#of its own.

#The same with read_csv function and
#other pandas functions that read diffrent file formats.
