# create a dataframe
x = {
	"Name": ["Harris", "Miss. Elizabeth"],
	"Age": [22, 58],
	"Sex": ["male", "female"]
	}
df = pd.DataFrame(x)

print(df.shape)
# this will print (2,3)

print('Number of rows = {0}'.format(df.shape[0]))
print('Number of columns = {0}'.format(df.shape[1]))
'''
this will print
Number of rows = 2
Number of columns = 3
