with statement odd feature
#1
an editing error exposed this to me which i did not find in the reference manual. on a with statement i omitted the "with_item", that is, the as followed by the variable name. but it still worked. i was using the variable f. so, i left it out, and removed it in another with statement. the script still works. maybe, some day, it will break.

is this supposed to happen? is this a Cpython glitch?

#!/usr/bin/env python3
import os,sys
a='~/.'+(sys.argv[0].rsplit('/',1)[1])
try:
 with open(os.path.expanduser(a+'-pre.py')):
  p=[x[:-1] for x in f]
except:
 p="""
import os
from subprocess import call,DEVNULL,PIPE,Popen,run
from sys import stderr,stdin,stdout,version_info
from time import sleep,time as secs
""".splitlines()
try:
 with open(os.path.expanduser(a+'-suf.py')):
  s=[x[:-1] for x in f]
except:
 s=[]
c='\n'.join(p+sys.argv[1:]+s)
if len(sys.argv)>1:os.execvp('/usr/bin/env',['env','python3','-c',c])
