how to apply filter in dataframe in python code example

Example 1: filter df by column value

# does year equals to 2002?
# is_2002 is a boolean variable with True or False in it
>is_2002 =  gapminder['year']==2002
>print(is_2002.head())
0    False
1    False
2    False
3    False
4    False

Example 2: pandas filter

df[(df['year'] > 2012) & (df['reports'] < 30)]
