Pipe character in Python
This is also the union set operator
set([1,2]) | set([2,3])
This will result in set([1, 2, 3])
It is a bitwise OR of integers. For example, if one or both of ax
or bx
are 1
, this evaluates to 1
, otherwise to 0
. It also works on other integers, for example 15 | 128 = 143
, i.e. 00001111 | 10000000 = 10001111
in binary.
Yep, all answers above are correct.
Although you could find more exotic use cases for "|", if it is an overloaded operator used by a class, for example,
https://github.com/twitter/pycascading/wiki#pycascading
input = flow.source(Hfs(TextLine(), 'input_file.txt'))output = flow.sink(Hfs(TextDelimited(), 'output_folder'))input | map_replace(split_words, 'word') | group_by('word', native.count()) | output
In this specific use case pipe "|" operator can be better thought as a unix pipe operator. But I agree, bit-wise operator and union set operator are much more common use cases for "|" in Python.
