Problem –
You want to add an empty column to a pandas dataframe.
Solution –
Let’s read a dataset to illustrate.
import pandas as pd
import numpy as np
url = 'https://raw.githubusercontent.com/bprasad26/lwd/master/data/Restaurant.csv'
df = pd.read_csv(url)
df.head()
Now, let’s say I want to add an empty column location to this dataframe. To do that I will just create a new column and fill it with np.nan.
df['location'] = np.nan
