Assignments to vars() behave incorrectly if those variables are use
later on in a function.
For example, try this:
======
#!/usr/bin/python
def zz():
for i in [1,2,3]:
for j in [4,5,6]:
vars()['fw_%s_%s' % (j,i)] = 'test %s %s' % (j, i)
print vars()['fw_%s_%s' % (j,i)]
fw_4_2 = 'zz'
print fw_4_2
zz()
======
The assignments work fine up till 4_2. At 4_2, the assignment apparently
fails silently, and the print raises a keyError exception.

According to http://docs.python.org/library/functions.html#vars >The returned dictionary should not be modified: the effects on the >corresponding symbol table are undefined. Same can be said for locals() as well. |
