from pyspark.sql import SparkSession
spark=SparkSession.builder.appName("boye").getOrCreate()
#spark = SparkSession.builder.appName("test").master("local[2]").getOrCreate() #运行在本地（local），2个线程
sc = spark.sparkContext

datas = ["hi I love you", "hello", "ni hao"]
sc = spark.sparkContext
rdd = sc.parallelize(datas).filter(lambda x:x.__contains__("he"))
print(rdd.collect())
print(rdd.count())
