As all objects in python are implemented via references, you can re-write your struct to look like this: class Node: def :param df: A PySpark DataFrame """ null_counts = df.select ( [sqlf.count (sqlf.when (sqlf.col (c).isNull (), c)).alias ( c) for c in df.columns]).collect () [0].asDict () # 1 How do I change the size of figures drawn with Matplotlib?

We just check for None in all the values extracted using the values function and check for existence using the in operator. Under CPython, the most popular Python runtime, id() does its job by reporting the memory address of an object. None is falsy, which means not None is True. Empty dictionary is also created by dict() built-in function without any arguments. In this case, you can define a class specifically for use as a default, while being distinct from None: Here, the class DontAppend serves as the signal not to append, so you dont need None for that.
