python - Concatenate numbers to URL in increasing order -


i want concatenate numbers in increasing order upto x in url. using:-

i=143  baseurl = 'https://example.com/listproduct/index/21/' + str(i)  while (i>0):     i-=1     print(baseurl)

instead of getting urls different end numbers, getting same i=143. proper way write above?

baseurl = 'https://example.com/listproduct/index/21/'  while (i>0):    i-=1    print(baseurl  + str(i))

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
