In many languages, such as C, one can use assignments in conditionals
and expressions. The most common, and useful case turns up when you
have if/else if/else if/else constructs. Consider the following
non-working pseudoPython.
import re
r1 = re.compile("hello (\d)")
r2 = re.compile("world([!?])")
w = "hello world!"
if m = r1.search(w):
handleMatch1(m)
elif m = r2.search(w):
handleMatch2(m)
else:
print("No match")
What you're looking for is a pocket function:
#untested
class assign(object):
def set(self, value):
self._assignment = value
return value
def get(self):
return self._assignment
m = assign()
if m.set(r1.search(w)):
handleMatch1(m.get())
elif m.set(r2.search(w)):
handleMatch2(m.get())
else:
print("No match")
