With a negative "step", python keeps on yielding¹ elements while the current value is greater than end. In this case, you start at 0. 0 is not greater than or equal to 10 so python's done and nothing gets yielded.

What does "for i in range" mean in Python?

Use a 'code block' in the 'new' reddit to paste code so we can see indents which are vital to python! for i in range(n + 1): sum = sum + i * i * i when you say 'for i in range(n + 1)' you are creating a variable called 'i' and setting it equal to the first value in the second part of the line called range(). every time the loop loops, i becomes the next value in the second part of the line (in this case range()) Check this code out to understand it: my_list = ['potato', 'pineapple', 'strawberry', 'banana', 'orange'] for var in my_list: #instead of 'i' i used 'var' you can use any name you want, since you are creating the variable. var is = to a value in my_list, and will go to the next value every time the loop loops. This will run a total of 5 times, because there are 5 items in the list we are looping through (my_list) print(var) now put that in your terminal/whatever and see the output, itll look like this: potato pineapple strawberry banana orange its the same with range() -- example: range(5) just means every number between 0 and 5, including 0 but not 5. so range(5) has 5 items, 0, 1, 2, 3 and 4. our loop should run 5 times: for i in range(5): print(i) you should see the output: 0 1 2 3 4 if you ever want to know more about certain parts of python, google it, for example: 'python range()' will give you tons of results that are helpful.

There is no evaluation of the first element by the range() call, and Python's range() function will not return anything if step is negative and start + i * step is not greater than stop. For your example, start = 0 + 0 * -1 is not greater than stop = 10, so your range call returns the empty list, and your for loop has nothing to iterate over.

$ python -c 'print(range(0,10,-1))'
[]

range()'s documentation:

range(stop)

range(start, stop[, step])

This is a versatile function to create lists containing arithmetic progressions. It is most often used in for loops. The arguments must be plain integers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns a list of plain integers [start, start + step, start + 2 * step, ...]. If step is positive, the last element is the largest start + i * step less than stop; if step is negative, the last element is the smallest start + i * step greater than stop. step must not be zero (or else ValueError is raised).

Python Program To Print Numbers From 1 to 10 Using For Loop

The range() function generates a sequence of numbers, starting from the first argument (1) up to, but not including, the second argument (11), similar to list indexing in range starts from 0 which means range( j )will print sequence till ( j-1) hence the output doesn’t include 11.

Here is a stack overflow question, might help you know what too google if you're still confused https://stackoverflow.com/questions/11364533/why-are-slice-and-range-upper-bound-exclusive There are a few reasons I understand: If your starting index is 0, the upper bound is the same as number of elements (if they're ints) so that's nice Cutting up consecutive sections is nice, since the upper bound of 1st slice is the beginning index of the next It doesn't really matter, some languages are upper bound inclusive. Someone just chose thus convention and it's kept for consistency

r/learnpython on Reddit: What does "for i in range" mean in Python?

September 9, 2019 -

So, I had a question where I was supposed to find the sum of the first natural numbers using Python.

Here's the problem:

Write a program to find the sum of the cubes of the first n natural numbers, where the value of n is provided by the user.

And this is the code that my professor used to allow the interpreter to produce the result:

= int(input("Enter a number:"))

sum = 0

for i in range (n+1): sum = sum + i*i*i

# for i in range starts as a loop, and then tries to get to (n + 1), whatever that may be

print("the sum of the first", n, "integers is", sum)

However, I can't seem to understand what "for i in range (n + 1): sum = sum + i * i * i" means. In other words, I don't understand what role this part of the code is doing to produce the result. Especially, I don't understand what the role of "for i in range (n + 1)" is doing. Does anyone mind explaining this to me?

It means that you're looping through the function body n times. So, for i in range(n) means that you're going to do something n times. For example: for i in range(10): print(n) means you're going to print the numbers 0 to 9, because the range function goes from 0 to n-1 if you provide a single argument, and from a to b if you provide two, as in range(a, b)
