In python, Suppose you have loaded up the data in some variable train:
train = pandas.read_csv('file_name')
>>> train
train([[ 1., 2., 3.],
[ 5., 1., 2.]],)
I want to check what are the dimensions of the 'file_name'. I have stored the file in train
>>>train.shape
(2,3)
>>>train.shape[0] # will display number of rows
2
>>>train.shape[1] # will display number of columns
3
