tags = ProductInStore.objects.get(id=product_in_store_id).product.tags.values_list('name', flat=True)
        converted_list = list(tags)
        tags_string = ''
        for tags in converted_list:
            tags_string  = ','   tags
        return tags_string

The output is

,tag1,tag2,tag3,tag4,tag5

but i'd like to get rid of the first comma. Do you have any idea how to do it?

CodePudding user response：

You can simply use the str.join(iterable) method instead of the for loop:

tag_string = ",".join(tags)

CodePudding user response：

return tags_string.lstrip(",")

CodePudding user response：

return tags_string.strip(",")

Note: it will also remove "," (if any) from the end of string.

You will have three approaches in front of you:

Option 1: Using for loop and enumerate

tags_string = ""
length = len(converted_list)
for index ,tags in enumerate(converted_list):
  if index != length:
    tags_string  =  tags   ","
  else:
    tags_string  =  tags
tags_string 

Option 2: Using lstrip

for tags in converted_list:
    tags_string  = ','   tags
tags_string.lstrip(",")

Option 3: Using join

",".join(converted_list)

All three approaches would result in the same output:

tag1,tag2,tag3,tag4,tag5
