将if条件与for循环混合

Question

我有以下for和if条件，for循环后跟if条件， 关于如何将它们组合成一行的任何建议？

for x in ids:
   if x!=12345

Answer 1

for x in (i for i in ids if i!=12345):
    # do stuff

In [37]: ids
Out[37]: [12343, 12344, 12345, 12346, 12347, 12348]

In [38]: for x in (i for i in ids if i!=12345):
   ....:     print x
   ....:     
12343
12344
12346
12347
12348
