Loops
Loops are used when there are multiple elements that need to undergo the same series of calculations
or same blocks of code. Typically, items are placed in a list and we write a for loop such that
the same block of code is executed across each element in the list.
The key here is that we are not copy-pasting code multiple times to perform this repeated action.
Given a list of integers, you can write a for loop to print each integer in the list.
Note, just like conditional statements, indentation matters.
int_list = [1, 2, 3, 4]
for value in int_list:
print(value)
1
2
3
4
This exercise will build on the previous example, but instead of a single value to test our binge drinking status, you will have a list of values.
