Could anyone explain to me the below exercise with for loop?
The solution
from robot_control_class import RobotControl
robotcontrol = RobotControl()
l = robotcontrol.get_laser_full()
maxim = 0
for value in l:
if value > maxim:
maxim = value
print ("The higher value in the list is: ", maxim)
Thanks in advance!
Hello @vasileios.tzimas ,
Could you specify a little bit more with your question? What is it that you donāt understand? Is it the exercise requirements? Is it the solution code? The entire code? A specific part of the code?
Thanks in advance,

Hello again! Yes, of course, I didnāt understand how to find the higher value of l. It will have 719 values. Also, what does in do in for loop?
The how is to check each value in the list (array) one by one to determine the largest value, and the for-loop can help you do that.
it means inside
The general structure of a for-loop is
for item in iterable_object:
# do something with item
and it simply means āfor every item inside this objectāā¦
That solution could be better written as:
from robot_control_class import RobotControl
robotcontrol = RobotControl()
laser_readings = robotcontrol.get_laser_full()
maxim = laser_readings[0] # the very first item, let's assume it's the largest for now
for value in laser_readings:
if value > maxim:
maxim = value
print ("The higher value in the list is: ", maxim)
- We set the first item in the
laser_readings
list as the largest to begin with. We store the value in maxim
.
- We then go over the items in the array one by one and check if they are larger than
maxim
.
- If any item is larger than
maxim
, we store itās value in maxim
so that it becomes the largest for the moment and move to the next element and check again. We repeat this check until we have checked all elements.
- By the time we finish checking all items, the largest value would have been stored in
maxim.
- Eventually, we print the value of
maxim
.
Thank you very much @bayodesegun !!
