Thank you for your inputing which has been great inspirational:)
What I tried to do is to write a string.split() module, so I started
with:
def spilt(a):
l=[]
index=0
if not isinstance(a, basestring): #Or isinstance(a, str)
return
for i in len(a):
if a[i]=' ':
item=a[index:i]
l.append(item)
..................
I'm still working on it:)
Thank you again
Peace
PS: Is str() the same as repr() ?
