I am learning python. I want to store one by one element in array or list. this is my code.
for u in durl:
p2 = requests.get(u)
tree = html.fromstring(p2.content)
dcode.append = tree.xpath(ecode)
print(dcode)
in dcode variable the elements are overriding not appending. i want to insert it one by one. please help me.
append is a method not a variable so if you want to append tree.xpath(ecode) to dcode then you should write dcode.append(tree.xpath(ecode)) rather than dcode.append = which is an assignment not a method call.
tree.xpath(...) returns a list so if you want to merge it with an existing list dcode of selected elements, you might do
dcode.extend(tree.xpath(ecode))
You can do it this way, it appends new value to the list and it makes more sense...sort of data structure
def main(decode=[]):
for u in durl:
p2 = requests.get(u)
tree = html.fromstring(p2.content)
dcode.append(tree.xpath(ecode))
print(dcode)
