Split() [solved with re.split]

[MaxLindquist]

How do make a split on a string at a few different places? For example i wanna make a split on 5*4+1-1+3 to put all the numbers in a list. How do i do that?

Hi,

This should do the job although I don't believe it is the best solution.


a = "1+2-3+5-6*8"
z = []
for x in a:
try :
int(x)
z.append(x)
except:
pass
print z

Geos, Please use code tags so your post looks like this:

a = "1+2-3+5-6*8"
z = []
for x in a:
    try :
        int(x)
    z.append(x)
    except:
        pass
print z
 

Otherwise, it is very hard to use. Thanks,
Barton

You can use a regular expression to split the string. You still have to go through the list to convert to integers as in the previous example though.

import re
re.split('[*+-]', '5*4+1-1+3')

This is VERY cool! I've used the re module, but hadn't come across this usage. Thanks Fredrik!

Here is a possible solution...

for a in "5*4+1-1+3".split("*"):
 for b in a.split("+"):
  for c in b.split("-"):
   print c
