I have a function, which I put into an expression like this:
def func(a, b=None):
global spam
import math
spam = [a, b]*3
print spam
del spam
value = [1, "hello", int, func]
del func
How would I use lambdak to write that as an expression
value = [1, "hello", int, ??????? ]
without the intermediate def?
# Untested, but seems like this should work.
value = [1, "hello", int, given_(lambda a, b=None:
import_("math", lambda math:
import_("operator", lambda operator:
do_(lambda: operator.setitem(globals(), 'spam', [a, b]*3), lambda:
print_(globals()['spam'], lambda:
do_(lambda: operator.delitem(globals(), 'spam')))))))]
To the OP: I note that although import_ is used in the examples, it's
not found in the list of functions in the README.
Just what I've been looking for, highly readable, higly maintainable
Python code. Please put this up as an Activestate recipe so it's
preserved for prosperity, so that the entire world can see its
asthetically pleasing properties.
