Regular Expression for Range (2-16)

With delimiters (out of habit): /^([2-9]|1[0-6])$/

The regex itself is just: ^([2-9]|1[0-6])$

Use the python package regex_engine for generating regular expressions for numerical ranges

You can install this package with pip.

pip install regex-engine

from regex_engine import generator

generate = generator()
    
regex = generate.numerical_range(2, 16)
    
print(regex)

^([2-9]|1[0-6])$

You can also generate regexes for floating point and negative ranges.

from regex_engine import generator

generate = generator()

regex1 = generate.numerical_range(5, 89)
regex2 = generate.numerical_range(81.78, 250.23)
regex3 = generate.numerical_range(-65, 12)

^([2-9]|1[0-6])$

will match either a single digit between 2 and 9 inclusive, or a 1 followed by a digit between 0 and 6, inclusive.

^([2-9]|1[0-6])$
