Write stdout to file - mcmxl22 - Dec-31-2016 I need the lines() function to write the results of a = [int(x) for x in str(i)] to fibo.txt but it's coming up empty.I have tried taking the f.write() out of the for loop but it has the same results. Do I need a separate function for f.write() ? def F(): a, b = 0, 1 yield a yield b while True: a, b = b, a + b yield b def subfib(StartNumber, endNumber): for cur in F(): if cur > endNumber: return if cur >= StartNumber: yield cur def lines(): for i in subfib(2, 400): a = [int(x) for x in str(i)] with open('fibo.txt', 'w') as f: f.write(a) f.close() lines() RE: Write stdout to file - Mekire - Dec-31-2016 Probably something like this? def F(): a, b = 0, 1 while True: yield a a, b = b, a + b def subfib(StartNumber, endNumber): for cur in F(): if cur > endNumber: return if cur >= StartNumber: yield cur def lines(): with open('fibo.txt', 'w') as f: for fib in subfib(2, 400): f.write("{} ".format(fib)) if __name__ == "__main__": lines()If this isn't what you need then you need to be more explicit about what the final file should look like.
