New submission from Reuven Lerner :
I just discovered that having whitespace inside of {min,max} causes the regexp
to report no matches, rather than an error:
>>> import re
>>> s = 'abbccce'
>>> re.findall('d{1, 4}', s)
[]
>>> re.findall('d{1,4}', s
New submission from Reuven Lerner :
Newcomers to Python are often frustrated and surprised when they define
variables such as "sum" and "list", only to discover that they've masked access
builtins of the same name.
External code checkers do help, but those don't work in J
