You forgot the required colon (":"). It should be
for i in range(len(list)): # note trailing colon

In addition, "list" is a reserved word in python and while you can rebind it, it usually not recommended. Unless IPython is different?

It seems to me that it would be simpler to simply do it like
this:
mylist = list
for var in mylist:
(var is an entry in the list - do with it whatever you want
to do)

to do)
The new name mylist should be used in the place where you
defined **your** list. (mylist = list is used as an indication
only; never use reserved name for a variable name - bad practice
that will lead to grief sooner or later).
