df = pd.DataFrame(columns=['A','B','C','D','E','F','G'])

Example 4: python initialise dataframe

import pandas as pd

data = [[0, 0, 0] , [1, 1, 1]]
columns = ['A', 'B', 'C']
df = pd.DataFrame(data, columns=columns)

Example 5: dataframe pandas empty

>>> df_empty = pd.DataFrame({'A' : []})
>>> df_empty
