Hi,
Is it not clear to me if you must distinguish ints from other type of
numbers, or if, for instances floats and ints must be dealt
differently.
Anyway, I would propose something like the following function:
def FindNumbers(a_string):
print "You entered:", a_string
out_list = []
for item in a_string.split():
try:
num = int(item)
except ValueError:
out_list.append(item)
else:
out_list.append("%s" % (num+a,))
out_string = ' '.join(out_list)
# do whatever you want to do with the resulting out_string:
return it, or display it...
Some comments:
1) I would pass the input string as argument rather than using it as a global.
2) You could use float instead of int to make it more general
3) If you need to distinguish between ints and floats, then you must
add a couple of extra lines
I hope it helps.
Best
