[MINOR][DOC] Use raw triple double quotes around docstrings where there are occurrences of backslashes. From [PEP 257](https://www.python.org/dev/peps/pep-0257/): > For consistency, always use """triple double quotes""" around docstrings. Use r"""raw triple double quotes""" if you use any backslashes in your docstrings. For Unicode docstrings, use u"""Unicode triple-quoted strings""". For example, this is what help (kafka_wordcount) shows: ``` DESCRIPTION Counts words in UTF8 encoded, ' ' delimited text received from the network every second. Usage: kafka_wordcount.py <zk> <topic> To run this on your local machine, you need to setup Kafka and create a producer first, see http://kafka.apache.org/documentation.html#quickstart and then run the example `$ bin/spark-submit --jars external/kafka-assembly/target/scala-*/spark-streaming-kafka-assembly-*.jar examples/src/main/python/streaming/kafka_wordcount.py localhost:2181 test` ``` This is what it shows, after the fix: ``` DESCRIPTION Counts words in UTF8 encoded, '\n' delimited text received from the network every second. Usage: kafka_wordcount.py <zk> <topic> To run this on your local machine, you need to setup Kafka and create a producer first, see http://kafka.apache.org/documentation.html#quickstart and then run the example `$ bin/spark-submit --jars \ external/kafka-assembly/target/scala-*/spark-streaming-kafka-assembly-*.jar \ examples/src/main/python/streaming/kafka_wordcount.py \ localhost:2181 test` ``` The thing worth noticing is no linebreak here in the help. ## What changes were proposed in this pull request?
