I'm struggling with nested loops in Python.
So say I want to:
Design a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. The outer-loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for the inches of rainfall for that month.
After all iterations, the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.
Now, I'm not asking you to do this for me. What I'm struggling with is how to set this up.
From what I understand I need to make 'years' a variable like
years = int(input('Type the number of years:')
and then use a for loop like:
for num in range(years):
rainfall = int(input('Enter the amount of rainfall for this month'))
right? Do I make a list containing each month? What is the nested loop going to look like inside?

Not asking for anyone to do it for me, I'm asking if I'm setting this shit up in the right direction.

Thanks

I uh... forgot to escape the code tag
use the code tag for code
Your nested loop would look like thisfor i in range(years):
#code
for j in range(12):
#code for asking rainfall per month
#code for putting data in list
#code
#code

Thanks fampai

They're certainly more difficult in python compared to nested lists.

Also, using a list for the months would be necessary I'm assuming?

If you want to have specific data for a specific year, a nested list like this[ [m1,m2...m12], #for year 1
[m1,m2...m12], #for year 2
...
[m1,m2...m12] ] #for year n
would be helpful.
Otherwise, you can just store each datapoint in a big list.
