I have this list, all the elements are float. Now i want to join them together with certain format for example exponent notation, so that I can print them out in one line.
So I did this
for line in fileinput.input(filename):
old_line = line.split()
new_line = [float(s) for s in old_line]
# some calculation
line_jn = ' '.join(['%15E' % (x for x in new_line)])
print >> fOUT, line_jn
I got the error msg:
line_jn = ' '.join()
TypeError: float argument required
But all the items in new_line are float, so x is float, where does it need float argument?
Alternatively, I don't have to do it this way, I can just print out the elements in the list new_line in one line with exponent notation. I know stdout.write can do that, but I am printing them to a file. Is there a way to do it?
Thanks in advance.
