>>> import tempfile >>> with tempfile.TemporaryDirectory(prefix="text") as d: ... # Write a DataFrame into a text file ... df = spark.createDataFrame([("a",), ("b",), ("c",)], schema=["alphabets"]) ... df.write.mode("overwrite").format("text").save(d) ... ... # Read the text file as a DataFrame. ... spark.read.schema(df.schema).text(d).sort("alphabets").show() +---------+ |alphabets| +---------+ | a| | b| | c| +---------+
