shape python pandas code example

Example 1: df.shape 0

count_row = df.shape[0]  # gives number of row count
count_col = df.shape[1]  # gives number of col count

Example 2: pandas shape

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

Example 3: .shape[0] python

In [46]: Y = np.arange(12).reshape(3,4)

In [47]: Y
Out[47]: 
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

In [48]: Y.shape
Out[48]: (3, 4)

In [49]: Y.shape[0]
Out[49]: 3
