I have to list a integers from a text file separated by newlines into a python list. I ended up with the code above which works (for my case) but certainly is far form optimal.
def readIntegers(pathToFile): f = open(pathToFile) contents = f.read() f.close() tmpStr = "" integers =  for char in contents: if char == '\r': integers.append(int(tmpStr)) tmpStr = "" continue if char == '\n': continue tmpStr += char return integers
Now I have much less code, but I'm not sure for which cases split() works correctly.
def readIntegers(pathToFile): with open(pathToFile) as f: a = [int(x) for x in f.read().split()] return a
