## Print series of number every 50

I need to paginate through an API and I am creating the URLs.

The URL looks like this:
`/search/officers?q=XXXXX&items_per_page=50&start_index={}`

The maximum items per page allowed in the returned JSON is 50, and based on the number of pages I need to change the `start_index={}`

string.

I calculated the number of pagination i need to execute by dividing the number of total results by the maximum items per page.

pages = 355 count_by_n = 50 for i in range(pages+1): if i is 0: print("start_index={}".format(i)) else: global count_by_n count_by_n += 50 print(str("start_index={}".format(str(count_by_n + 1))))`

which produces:

start_index=0 start_index=101 start_index=151 start_index=201 start_index=251 start_index=301 start_index=351 start_index=401 <>:7: SyntaxWarning: name 'count_by_n' is assigned to before global declaration

Technically it is the result i want but I was wondering if there was a way to get around that message and maybe solve this with recursion.

Yes, you can specify the `start`

(inclusive), `stop`

(exclusive) and `step`

in a range, so you can write this as:

pages = 123 count_by_n = 50 for i inrange(1, 50*pages + 1, 50): print('start_index={}'.format(i))

This then yields:

>>> pages = 355 >>> for i in range(1, 50*pages + 1, 50): ... print('start_index={}'.format(i)) ... start_index=1 start_index=51 start_index=101 start_index=151 start_index=201 start_index=251 start_index=301

**Python range() Function Explained with Examples,** print("Python range() example") print("Get numbers from range 0 to 6") for i in The step is a difference between each number in the result. 1 is 20 List item at index 2 is 30 List item at index 3 is 40 List item at index 4 is 50. Print Number Series in C - In c language you can print any number series. Here i will show you how to print number series in c language with explanation. In case of print number series you need to focus on common difference between two numbers.

As you already calculated your pagination, IMHO the easiest solution would be to simply iterate over that range and print `50*i + 1`

:

pages = 355 for i in range(pages): print(f'start_index={50*i+1}') # start_index=1 # start_index=51 # start_index=101 # ... # start_index=17601 # start_index=17651 # start_index=17701

And if you do *not* want to calculate the number of pages beforehand, because you want to do that loop based on the number of urls `n`

, I'd recommend to do

n = 17710 for i in range(0, n, 50): print(f'start_index={i+1}')

for the sake of readability.

**Print numbers from 1-50,** This will correctly print each number in sequence, but relies on features of Bash that aren't portable across shells. If you need portability, consider� In c++ language you can print any number series. Here i will show you how to print number series in c language with explanation. In case of print number series you need to focus on common difference between two numbers..

The `SyntaxWarning`

occurs because `global count_by_n`

is being evaluated multiple times in the for loop and, more importantly, after a value has already been assigned to the variable. In order to get rid of the warning you should use the `global`

keyword only once per variable (and thus outside the for loop) and **before assigning a value**, like so:

pages = 123 global count_by_n count_by_n = 50 for i in range(pages+1): if i is 0: print("start_index={}".format(i)) else: count_by_n += 50 print(str("start_index={}".format(str(count_by_n + 1))))

**R Programming: Create a sequence of numbers from 20 to 50 and ,** print("Sequence of numbers from 20 to 50:") print(seq(20,50)) print("Mean of print("Sum of numbers from 51 to 91:") print(sum(51:91)). Program to display even numbers from 1 to n where n is 100. In the following example we are displaying the even numbers from 1 to n, the value of n we have set here is 100 so basically this program will print the even numbers between 1 to 100.

**Python Exercise: Fibonacci series between 0 to 50,** Note : The Fibonacci Sequence is the series of numbers : 0, 1, 1, 2, 3, 5, 8, 13, 21, . Every next number is found by adding up the two numbers before it. Pictorial Python Code: x,y=0,1 while y<50: print(y) x,y = y,x+y. Sample� Method:2 Even numbers between 1 to 100. In second method we use ‘for’ loops and ‘if’ condition to print even numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 1, when ‘if’ condition will be true, it print even numbers.

**Python Program to Print Numbers in an Interval,** Given a range of numbers, find all the numbers between them. Input : l = 2, u = 5. Output : 2 3 4 5. Input : l = 10, u = 20. Output� Problem Definition Create a Python program to print numbers from 1 to 10 using a for loop. Solution In programming, Loops are used to repeat a block of code until a specific condition is met. A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. Also, we are going to use one of Python’s built-in function

A Prime number is a natural number greater than 1 that is only divisible by either 1 or itself. All numbers other than prime numbers are known as composite numbers. There are infinitely many prime numbers, here is the list of first few prime numbers 2 3 5 7 11 13 17 19 23 29 31 37.

- Why do you start with
`start_index=0`

? Furthermore`51`

is missing. - Cuz the first page is from 0 to 50, the second page from 51 to 100. Yes, I figured after posting, editing now.
- but that does not make much sense, either the first page is from 1 to 50 (and the second from 51 to 100), or the first page is from 0 to 49, and the second from 50 to 99. Otherwise the two pages have a different number of elements. It is also not in "harmony" with the later requests you do, since then you fetch from
`101`

to`151`

which thus makes a hop of 50, not of 51. - You're right it's from 1 to 50 - 51 to 100 etc...
- No, this is wrong. The syntax error is thrown because the variable which is declared as global is already used before this declaration. This is btw also written in the error message: "
*name 'count_by_n' is assigned to before global declaration*". Besides that there is no need to declare anything to be global in this context. Test your own code without this line. - I did test this code and it works without warnings because here global is used before assigning a value: fixing the exact problem the warning was about. Check your words before posting a comment.
- If I should check my words - why did you edit your answer accordingly? However - checking words before replying is a good advice: Note that I didn't doubt that you checked your code. I asked you to check your code
*after deleting the line*`global count_by_n`

. Because global is not needed here. Of course using it doesn't result in a warning, but that's not a good reason to use any statement, right?
