Why does the function return each element of the list on a new line?

So i have this code right here to separate only ints or floats out of a file and add them to a list, however when it returns the list, it returns each element on a new line and not the entire list on the same line, and I’m wondering why?
the list looks kind of like this:
12 w 21 d23g780nb deed e2 21.87
43 91 – . 222 mftg 21 bx .1 3 g d e 6 de ddd32 3412

def read_numbers(path: str) -> list:
    with open(path) as f:
        file_elem = f.read().split()
    a = []
    for x in file_elem:
        if x.isnumeric():
            a.append(int(x))
        elif "." in x:
            b = x.replace(".","")
            if b.isnumeric():
                a.append(float(x))
    return a

If I remove the looking for floats part it will only add the ints to the list but it will return the list as intended,
Out[101]: [12, 21, 43, 91, 222, 21, 3, 6, 3412, 0, 0, 0, 1, 70, 12, 1, 9, 445, 100]
however when adding the floats, it seems that the entire list gets messed up like this

and i’m wondering why?

>Solution :

I created a file like this:

file a:

12 43 12.145 546 23 76 5.54 231.1 32

then I run your code like this:

In [3]: def read_numbers(path: str) -> list:
   ...:     with open(path) as f:
   ...:         file_elem = f.read().split()
   ...:     a = []
   ...:     for x in file_elem:
   ...:         if x.isnumeric():
   ...:             a.append(int(x))
   ...:         elif "." in x:
   ...:             b = x.replace(".","")
   ...:             if b.isnumeric():
   ...:                 a.append(float(x))
   ...:     return a
   ...:

In [4]: read_numbers('./a')
Out[4]: [12, 43, 12.145, 546, 23, 76, 5.54, 231.1, 32]

And so everything is OK.

UPDATE:

I changed file like this:

new file a:

12 43 12.145 546 23 76 5.54 231.1 32
ad
adfad ga 235 1.12
adf a1 12 si
124 sd  1.12

and so output is like this:

In [5]: read_numbers('./a')
Out[5]: [12, 43, 12.145, 546, 23, 76, 5.54, 231.1, 32, 235, 1.12, 12, 124, 1.12]
