Summary: patch for new func. string.findall
Initial Comment:
this finds all indices of a substring in a string
returning in list form. Its not in pydoc2.3.
This "patch" contains unittests.
#!/usr/bin/python
import string
def findall(sub,s):
if s =='' or sub =='':
return []
ret=[]
findval=0
pos=0
while findval != -1:
findval = s.find(sub,pos)
if findval != -1:
ret.append(findval)
pos = findval + len(sub)
return ret
if __name__ == '__main__':
units = [
'asdsad','l',
'l','asdlsds',
'l','lsdlsds',
'l','lsdsds',
'l','sdsds',
'l','sdsdsl',
'l','lsdsdsl',
'l','lsdlsdsl',
'l','l',
'l','ll',
'l','lll',
'lo','llollol',
'lo','llollolo',
'','',
'','asdasd',
'asdsad',''
]
for i in range(0,len(units),2):
sub,s = units[i],units[i+1]
print "'%s' in '%s':"%(sub,s)
print findall(sub,s)
print "-"*30
print 'done'

The string module is deprecated so adding anything to the module is a big
no-no. If you still want to see this functionality it will require being added to
the string type.
I am also changing this to a patch since it has working code (albeit as-is it
would be rejected).

This might be done as an iterator as well, as re.findall
also is complemented by an re.finditer.
