System information.

• Have I written custom code (as opposed to using a stock example script provided in Keras): NA
• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): NA

Describe the problem.

Absent comma results in unwatned string concatenation on line 330:

tensorflow/tensorflow/python/keras/engine/training_generator_test.py

Lines 330 to 336 in 0d8705c

	x = [
	'I think juice is great',
	'unknown is the best language since slicedbread',
	'a a a a a a a',
	'matmul'
	'Yaks are also quite nice',
	]

So 'matmul' gets appended with 'Yaks are also quite nice' resulting in matmulYaks are also quite nice being used in the test.

Describe the current behavior.

'matmulYaks are also quite nice' is used in the test

Describe the expected behavior.

'matmul', 'Yaks are also quite nice' is used in the test
