Python code of this video:

import pandas as pd # Load pandas

data = pd.DataFrame({'x1':range(5, 10), # Create pandas DataFrame
'x2':range(10, 15),
'x3':range(20, 25)})
print(data) # Print pandas DataFrame

for i in range(1, 4): # Append columns within for loop

The loop is not a good idea when you have several (200, 300, ...) columns to add. We have maybe use Dask or Multiprocessing...
