Each Answer to this Q is separated by one/two green lines.
I have a
var_1 = "hello" , and I want to convert it to a single element
list, I try this:
>>> list(var_1) ['h', 'e', 'l', 'l', 'o']
which is not the
['hello'] that I want.
How do I do that?
Just put square brackets
>>> var_1 = "hello" >>> [var_1] ['hello']
var1 = [var1] accomplish what you’re looking for?
Just do the following:
var_1 = ['hello']
It can be useful to add a check before doing so, as such:
if not isinstance(var_1, list): var_1 = [var_1]
A use case for this code is in functions that can take either a string or a list of strings and want the functions to handle that silently. E.g.:
def dataframe_key_columns(dataframe, keys): if not isinstance(keys, list): keys = [keys] return [dataframe[key] for key in keys]
Let me provide you a much easier and authentic way to do it.
You will get a list with ‘hello’ as its element.
And you can use the list L anyway you like.
