generator function that yield from a list

[buran]

Let's say we have a string lie this 'a b c' (simplified example)
so we can do

spam = 'a b c'
for ch in spam.split(' '):
    print(ch)

in this case str.split() will produce a list (i.e. it will generate the whole list in memory)

for same result we can do also

def chars(eggs):
   for ch in eggs.split(' '):
       yield ch

spam = 'a b c'
for ch in chars(spam):
    print(ch)

in this case the generator function chars will not produce the list from eggs.split() in memory, right? it will be evaluated lazy? I started to doubt myself today answering on SO question...
