This is a slightly confusing issue for new programmers in Python that have experience in object-oriented or procedural languages (c, Java etc.)

The difference between those languages is that Python does not support a "counting"-like for iteration that is constantly used in C,Java etc :

for(i = 0; i < 10; i++){
...
}

In contrast, Python implements only a for that is similar to the Iterator interface of object-oriented languages (Java programmers will be familiar with this) :

for object in object_list
    ....

So, in your example "range"[1,101] is the list (object_list) containing all numbers from 1 to 100 and "number" is the iterator (object) that takes the place of each one number
