And so you can change it to:.
Expanding further, rather than using str. This has the benefit that it will escape ' and " characters for you, which your code doesn't correctly handle. Thanks Mathias. When you would try to use list later on you'd get an Error. You need to send a string. Instead of creating a list and then converting to a string you can build the string from the start.
EDIT: I only just noticed that using this was recommended at the bottom of an already existing answer - but I think this deserves a full answer. I consider it much cleaner than the potentially inaccurate string manipulation answers. Sign up to join this community. The best answers are voted up and rise to the top.

It is also possible to delete items using del statement by specifying a position or range with an index or slice. You can remove the item at the specified position and get the value of that item with pop. You can use negative values to specify the position from the end.
The index at the end is You can remove the first item from the list where its value is equal to the specified value with remove.
You can also remove elements from a list with del statements. Specify the item to be deleted by index. The first index is 0and the last index is Removing items that satisfy the condition is equivalent extracting items that do not satisfy the condition.
In the list comprehension, a new list is generated. Unlike the list type method or del statement introduced so far, the original list is not changed. Remove all items: clear Remove an item by index and get its value: pop Remove an item by value: remove Remove items by index or slice: del Remove multiple items that meet the condition: List comprehensions See the following post for adding items to the list.

After I assign a string to a variable, I know that the print function will remove the single quotes around the value, but is there a way to assign a variable without the quotes around the value? I need a new variable which has the quotes omitted because from there the script will take the value of the last variable which is a path to a fileand tar up that file.
It won't recognize the path to the file if the value has quotes around it. If not, what's an alternative? Last edited by linuxuser; at PM. Last edited by dugan; at PM.

Each element or value that is inside of a list is called an item. Just as strings are defined as characters between quotes, lists are defined by having values between square brackets [ ]. Lists are great to use when you want to work with many related values.
How to strip both single and double quotes
They enable you to keep data together that belongs together, condense your code, and perform the same methods and operations on multiple values at once. When thinking about Python lists and other data structures that are types of collections, it is useful to consider all the different collections you have on your computer: your assortment of files, your song playlists, your browser bookmarks, your emails, the collection of videos you can access on a streaming service, and more.
As an ordered sequence of elements, each item in a list can be called individually, through indexing. Lists are a compound data type made up of smaller parts, and are very flexible because they can have values added, removed, and changed. Each item in a list corresponds to an index number, which is an integer value, starting with the index number 0. The first item, the string 'shark' starts at index 0and the list ends at index 4 with the item 'anemone'. The index numbers for this list range from 0 - 4as shown in the table above.
So to call any of the items individually, we would refer to the index numbers like this:. In addition to positive index numbers, we can also access items from the list with a negative index number, by counting backwards from the end of the list, starting at This is especially useful if we have a long list and we want to pinpoint an item towards the end of a list.
So, if we would like to print out the item 'squid' by using its negative index number, we can do so like this:. We were able to concatenate the string item at index number 0 with the string 'Sammy is a '. We can use indexing to change items within the list, by setting an index number equal to a different value. This gives us greater control over lists as we are able to modify and update the items that they contain. If we want to change the string value of the item at index 1 from 'cuttlefish' to 'octopus'we can do so like this:.

It looks as though you have a kind of CSV where either all elements, or at least all string elements, are surrounded by quotation marks.
