Super newbie trying to understand certain concepts

[SheeppOSU]

I found it hard to understand first as well
My definition of a for loop where it's for a in array the for loop will go through every object in array and each time, the object can be identified as a.

Here's an example

array = ['start', 1, 3, 2, 'finish']
for item in array:
    print(item)

Output:
start
1
3
2
finish

array = range(1, 26) #Returns all the number 1-25 (It doesn't include the 26)
for number in array:
    print(number)

Output:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

I hope this helps
