        fd2.close()

        print time.ctime()

        print " ending thread\n"

i=-1

while i<0:

current = testit()

time.sleep(0.001)

current.start()

I'm getting an error stating invalid syntax for the line:

print time.ctime()

Please help me out.

回答1:

This is because (in Python 3.0 onwards at least), print is a function.

Use:

print (time.ctime())

and it should be fine.

回答2:

From this page:

ctime(...)

ctime(seconds) -> string

Convert a time in seconds since the Epoch to a string in local time.

This is equivalent to asctime(localtime(seconds)).

ctime requires an argument and you aren't giving it one. If you're trying to get the current time, try time.time() instead. Or, if you're trying to convert the current time in seconds to a string in local time, you should try this:

time.ctime(time.time())
