Hey guys!
I’m doing a separate project…This is my code…
new = []
def extract_nums(string):
trash = []
for x in string:
if x.isalpha:
trash.append(x)
else:
new.append(x)
print new
extract_nums("hello 123")
Apperently, it only prints two brakets, []
@drewteriyaki,
Try it with Duck typing
def extract_nums(string):
new = []
trash = []
for x in string:
try:
x = int(x)
trash.append(x)
except Exception:
new.append(x)
print("isalpha: {0}".format(new))
print("trash : {0}".format(trash))
extract_nums("hello 123")
Hey Drewteriyaki,
Swap the order around so you’re printing new
after running extract_nums
- new
is empty by default, and so has to be modified before being printed if you want to have anything in it when you print the list
