groupby
suggest changeIntroduction
In Python, the itertools.groupby()
method allows developers to group values of an iterable class based on a specified property into another iterable set of values.
Syntax
- itertools.groupby(iterable, key=None or some function)
Parameters
| Parameter | Details | | —— | —— | | iterable | Any python iterable key |Function(criteria) on which to group the iterable
Remarks
groupby() is tricky but a general rule to keep in mind when using it is this:
Always sort the items you want to group with the same key you want to use for grouping
It is recommended that the reader take a look at the documentation [here] 1 and see how it is explained using a class definition.
