PYTHON 3: Iterators and Iterator Decorators via Generators (Please answer ALL parts (a & b), they're connected to each other. THANK YOU!) **if an argument is iterable, it means that you can call only iter on it, and then call next on the value iter returns (for loops do this automatically). There is no guarantee you can call len on the iterable or index/slice it. You may not copy all the values of an iterable into a list (or any other data structure). You may create local data structures storing as many values as the arguments or the result that the function returns, but not all the values in the iterable. 1) Write generators below that satisfy the following specifications. You may not import any of the generators in itertools or any other modules to write your generators. You may use any of the standard functions like zip and enumerate. a. The sequence generator takes any number of iterables as parameters: it produces every value from the first iterable, followed by every value from the second iterable, etc.,. Hint: I used only for loops. For example prints abcdefghi: all characters from 'abc', followed by all in 'd', followed by all in 'ef' etc.. b. The group_when generator takes one iterable and one predicate as parameters: it produces lists that each end in a value from the iterable where the predicate is True. If the iterable ends on a value for which the predicate returns False, yield a final list containing all the values from the one after the previous end to the last value produced by the iterable. Hint: I used a for loop . For example

prints the 5 lists['c', 'o']['m', 'b', 'u']['s', 't', 'i']['b', 'l', 'e']['s'].

for i in sequence ('abc', 'd', 'ef', 'ghi'): print ( i , end-' ' ) for i in sequence ('abc', 'd', 'ef', 'ghi'): print ( i , end-' ' )
