[New-bugs-announce] [issue27738] odd behavior in creating list of lambda expressions

[John Sahr]

New submission from John Sahr:

The following produces unexpected behavior.
I think that it should produce a list of six different lambda expressions,
but after creation, all six lambda expressions produce the same output.
It's possible that I'm missing something about Python.

##### begin example #######
from math import *

mm = []

for n in range(6):
    f = lambda x: sin(n*x)
    print f, f(1.0)
    mm.append(f)
    
print '***'

for m in mm:
    print m, m(1.0)
###### end example ####
