Python: request to add a variable in url

Question

Since I am using a for loop to request a URL which changed with a constant number, how can I parsed the variable in?

    total_page = 4
    for y in range (total_page):
        variable = 20*y+1
        base_url = 'https://abcd.com/r='
        url = ''.join([base_url, variable])
        finviz1 = requests.get(url)

However, an error occurred

    url = ''.join([base_url, variable])
TypeError: sequence item 1: expected string or Unicode, int found

How to eliminate the error?

variable is an integer, while string.join expects a list of strings. Convert variable to string by variable = str(variable) — muyustan

It expects all elements of the array to be a string, whereas you are passing variable as an integer. Convert it into a string before passing it, like this:

url = ''.join([base_url, str(variable)])
