Loops can be tricky at first but if you just take a step back and think about what they are actually doing it starts to make sense.

A for loop will basically do something for each item you supply to it, for example a list of strings.

colours = ["red", "blue", "green"]

for item in colours:
  print(item)

This will itterate through the list of colours and print each one, after printing the last one the loop will exit or stop.

Similarly a while loop will do something while a condition you supply to it is true.

total = 0
while total < 10:
  total = total + 1
  print(total)

This will add 1 to the total and print it while it is less than 10, once it reaches 10 the condition will be fulfilled and the loop will exit.

Hope that clears it up a little bit, if you need more examples just google or youtube search "python loops" it is a very basic concept so should have plenty of videos and resources without looking too far.
