What is the iterator (loop) variable in the following? rest = ["sleep", 'dormir', 'dormire', "slaap", 'sen', 'yuxu', 'yanam']
let = ''
for phrase in rest:
let += phrase[0]
The iterator variable is:.

The iterator variable is phrase

Explanation:

Given:

The above code segment

Required

Determine the iterator variable

The given code segment is written in python;

To determine the iterator variable, we simply make use of the following syntax:

for iterator-variable in iterable:

Compare this syntax to the instruction on line 3

for phrase in rest:

We have that the

iterator-variable = phrase

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
