在文件和终端标准输出python 2.7中打印输出

Question

I've added the following line to a python file in order to output all print strings to a file:

sys.stdout = open(logf, 'wb')

This does what I wanted, but also stops all print strings from appearing in the terminal. Is there a way to configure stdout to print to both destinations? (I'm trying to avoid writing a function for each use of print because there are many and it's a lot to rewrite. Also, I've perused several similar topics, but I haven't found a simple method.)

Answer 1

def fprint(output):
    print output
    with open("somefile.txt", "a") as f:
        f.write("{}\n".format(output))

This function would do it for you, use instead of print.
