Examples of the comparison of the array data ( list and numpy ndarray).

# Comparison of the 'list'
####################################

# In case of the 'list' data, 
# the result of the comparison using '==' and/or '!=' 
# is whether all the elements meet the condition.
# The result is just 'True' or 'False', not elementwise.

# Comparison of the numpy 'ndarray'
##############################################

# In case of the 'ndarray' data, 
# the result of the comparison using '==' and/or '!=' is elementwise.
# If you want to check whether all the elements meet the condition,
# use '.all()' command of the numpy or 'all()' command of the native python.

test_data = np.array([1,2,3])
test_data1 = np.array([0,2,3])
actual = np.array([1,2,3])

# element wise comparison
print(test_data == actual)
# [out] >> [True, True, True]
print(test_data1 == actual)
# [out] >> [False, True, True]

# comparison of all the elements
# Using .all() command of the numpy
print((test_data == actual).all())
# [out] >> True
print((test_data1 == actual).all())
# [out] >> False

# Using all() command of the native python
print(all(test_data == actual))
# [out] >> True
print(all(test_data1 == actual))
# [out] >> False
