Python Python Basics (Retired) Putting the "Fun" Back in "Function" Functions

Make a function named add_list that takes a list. The function should then add all of the items in the list together....

can some one please just help me understand whats going on. I checked another post it had the answer but I still do not get it. whats the for loop doing exactly? how is the for loop returning 6?

functions.py
def add_list(my_list):
  total = 0
  for item in my_list:
    total = total + item
  return total

# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.

I think its best off for me to start the python basic track again. I always find it easy going through the videos, but when it comes to the code challenges I forget everything. How can I improve this?
