Python List to String Conversion

Question

This seems like a simple task and I'm not sure if I've accomplished it already, or if I'm chasing my tail.

values = [value.replace('-','') for value in values] ## strips out hyphen (only 1)
            print values ## outputs ['0160840020']
            parcelID = str(values) ## convert to string
            print parcelID ##outputs ['0160840020']
            url = 'Detail.aspx?RE='+ parcelID ## outputs Detail.aspx?RE=['0160840020']

As you can see I'm trying to append the number attached to the end of the URL in order to change the page via a POST parameter. My question is how do I strip the [' prefix and '] suffix? I've already tried parcelID.strip("['") with no luck. Am I doing this correctly?

your first line is a list comprehension so you are making another list. You need to pull items out of that list as you need them. — Paul Seeb, Jan 28 '13 at 18:35
It looks like `values` is already a list of strings. Do you really need that `str()` cast? — kojiro, Jan 28 '13 at 18:37

values is a list (of length 1), which is why it appears in brackets. If you want to get just the ID, do:

parcelID = values[0]

Instead of

parcelID = str(values)

There's also `''.join(values)` – kojiro Jan 28 '13 at 18:33

Assuming you actually have a list of values when you perform this (and not just one item) this would solve you problem (it would also work for one item as you have shown)

values = [value.replace('-','') for value in values] ## strips out hyphen (only 1)

# create a list of urls from the parcelIDs
urls = ['Detail.aspx?RE='+ str(parcelID) for parcelID in values]

# use each url one at a time
for url in urls:
    # do whatever you need to do with each URL

Use the Following code to select single value from multiple value of list randomly and then convert this value to the string

location_list=["Pakistan","China","Rusia","UAE","USA","UK","Saudia Arab"]
loc=random.choice(location_list)
print(str(location_list[0]))
