I don t understand what s happening when the following function is called:
def doSmth(inFile): print inFile with open(inFile, r ) as trainSet: for instLine in trainSet: # do smth yield instLine
why when the last line with yield is removed there s an error that the file doesn t exist (it really doesn t exist). Whereas, when I have the line , there s no error. Another question, why in the second case, print inFile has no effect while it has in the first case. Thanks.
