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

`l = l[0]`? Or could there be more than one element? – Tim Pietzcker Jan 28 '21 at 14:26

There could be more than one element @TimPietzcker – M_Arora Jan 28 '21 at 14:27

Please show an example. – Tim Pietzcker Jan 28 '21 at 14:27

This gives me an error ```TypeError: 'float' object is not subscriptable ``` @MatsLindh – M_Arora Jan 28 '21 at 14:29

1@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]
