Example 1: dataframe create

>>> df2 = pd.DataFrame(np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]),
...                    columns=['a', 'b', 'c'])

import pandas as pd 
  
# initialize list of lists 
data = [['Group A', 85], ['Group B', 92], ['Group C', 88]] 
  
# Create the pandas DataFrame 
df = pd.DataFrame(data, columns = ['Name', 'Score']) 
  
# print dataframe. 
df

Example 3: creating a pandas df

>>> d = {'col1': [1, 2], 'col2': [3, 4]}
>>> df = pd.DataFrame(data=d)
>>> df
   col1  col2
0     1     3
1     2     4
