Sirs:

I'm confused?
 >>>"the rain in spain falls mainly on the plain"
 >>> "falls " in "the rain in spain falls mainly on the plain"
1
         #"in" looks like a yes or no test.#
 >>>a = "the rain in spain falls mainly on  the plain"
 >>> "falls" in a.split()
1
 >>>print a.find("falls")
18
 >>>a.find("falls")
18
 >>>b = "the rain in spain falls mainly on the plain in june"
Is there a way to use find to "see" the second "in" in the above example?
A reverse find?
TIA
Re-v  ?
