convert list of list of float into one list

Question

This is a pretty basic question but I cannot get the answer. I have a list l = [[1500.0]] and I wish to convert it into l = [1500.0] but I am unable to do so. I've tried:

[float(x) for [x] in elements_in_l]

Thanks in advance!

Since you already have floats inside your list in your list, `[x[0] for x in l]` should be enough — MatsLindh, Jan 28 '21 at 14:25
This gives me an error ```TypeError: 'float' object is not subscriptable ``` @MatsLindh — M_Arora, Jan 28 '21 at 14:29
@M_Arora In that case you don't have the list you've included in your example. `l = [[1500.0]]`, `[x[0] for x in l]` => `[1500.0]`. — MatsLindh, Jan 28 '21 at 14:45

Use list comprehension:

lst = [item for sublist in l for item in sublist]
