python - Pyspark convert a standard list to data frame

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/48448473/pyspark-convert-a-standard-list-to-data-frame

Answer 1

This solution is also an approach that uses less code, avoids serialization to RDD and is likely easier to understand:

from pyspark.sql.types import IntegerType

# notice the variable name (more below)
mylist = [1, 2, 3, 4]

# notice the parens after the type name
spark.createDataFrame(mylist, IntegerType()).show()

NOTE: About naming your variable list: the term list is a Python builtin function and as such, it is strongly recommended that we avoid using builtin names as the name/label for our variables because we end up overwriting things like the list() function. When prototyping something fast and dirty, a number of folks use something like: mylist.
