add new column to dataframe based on 3 conditions of row code example
Example 1: add a value to an existing field in pandas dataframe after checking conditions
# Create a new column called based on the value of another column
# np.where assigns True if gapminder.lifeExp>=50
gapminder['lifeExp_ind'] = np.where(gapminder.lifeExp >= 50, True, False)
gapminder.head(n=3)
Example 2: add a value to an existing field in pandas dataframe after checking conditions
gapminder['gdpPercap_ind'] = gapminder.gdpPercap.apply(lambda x: 1 if x >= 1000 else 0)
gapminder.head()
