This library provides functions that allow you to define a string that contains brackets with numeric-ranges, and then expands that into a list of actual values.
There are two functions defined. The first function bracket_expansion
will create a generator. You can then iterate through the generator.
The expansion supports multiple brackets. See examples.
If you want to create a concrete list from the generate, there is
a function called expand
which will do this as a convenience.
$ pip install bracket_expansion
Simple example:
from bracket_expansion import bracket_expansion
for if_name in bracket_expansion("Ethernet[1-48]"):
print(if_name)
Would result in the output:
Ethernet1
Ethernet2
Ethernet3
...
Ethernet48
Multiple brackets:
You can define multiple brackets in the expression:
from bracket_expansion import bracket_expansion
for if_name in bracket_expansion("Ethernet[1-2]/[1-10]"):
print(if_name)
Would result in the output:
Ethernet1/1
Ethernet1/2
...
Ethernet1/10
Ethernet2/1
Ethernet2/2
...
Ethernet2/10
For more details see the bracket_expansion
docstring.
