2,110 Pointslost on FOR syntax
how to interperate the Help() info, is there a help for the help?
the syntax is not understood from this
The "for" statement
The "for" statement is used to iterate over the elements of
a sequence
(such as a string, tuple or list) or other iterable object:
for_stmt ::= "for" target_list "in" expression_list ":"
suite
["else" ":" suite]
What do I need to do if the above is in comprehensible ??
def loopy(items):
for(items):
print(itmes)
if items = "STOP" : break

The syntax has 4 parts:
- keyword for
- loop variable, say, item
- keyword in
- an iterable or container object (such as a list, string, dict or other iterable)
In your case, the iterable is items, you need to provide a loop varaible. This is sometimes a "singular" for of the iterable name.
def loopy(items):
for item in items: # each time through loop take one element from 'items', assign it to 'item'
print(item)
if item == "STOP:
break
