Day #214 - Python Working with Arrays / Data Collection

	#Working with arrays
	import numpy as np
	a = np.array([[1,2,3],[3,4,5]])
	print('a')
	print(a)
	#Reshape as three rows 2 columns
	b = a.reshape(3,2)
	print('b')
	print(b)
	#Reshape as two rows and three columns
	c = a.reshape(2,3)
	print('c')
	print(c)
	#Transpose
	d = a.T
	print('d')
	print(d)
	#Can only specify one unknown dimension
	#unknown dimension for rows but two columns
	e = a.reshape(-1,2)
	print('e')
	print(e)
	#2 rows one unknown dimension for columns
	f = a.reshape(2,-1)
	print('f')
	print(f)
	#parse the array
	i = 0
	print('print values of a')
	for row in a:
	for value in row:
	print('position',str(i))
	i = i+1
	print(value)
