To create a DataFrame with this list of tuples, we will simply use pandas.DataFrame() method inside which we will pass a list of tuples, but we have to pass a parameter called columns=[] for which we will assign
You can create a DataFrame from a list of simple tuples, and can even choose the specific elements of the tuples you want to use. Here we will create a DataFrame using all of the data in each tuple except for the last element. import pandas as pd data = [ ('p1', 't1', 1, 2...

I would like to combine several iterators together, however instead of having a tuple, I would like the values to be "named", as in a dict or a namedtuple. This would allow to gain some abst... Turing Machine - Learning Skills

Finally, let’s create an RDD from a list. Note that RDDs are not schema based hence we cannot add column names to RDD. # Convert list to RDD rdd = spark.sparkContext.parallelize(dept) Once you have an RDD, you can also convert this into DataFrame. ...

I wanted to use jsonpickle for a bioinformatics project of mine, but this behavior is a killer; I regularly have dataframes with lists of floats. Could an implementation like this, which stores lists as lists of tuples of (value, type), be useful? It roughly doubles the size of the re...
