You need to convert the elements to strings.

print (", ".join(map(str, Floatlist)))

or

print (", ".join(str(f) for f in Floatlist)))

.join only operates on iterables that yield strings. It doesn't convert to strings implicitly for you -- You need to do that yourself:

','.join([str(f) for f in FloatList])

^{^{','.join(str(f) for f in FloatList) also works (notice the missing square brackets), but on CPython, it's pretty well known that the version with the list comprehension performs slightly better.}}

You just make a for statement:

for i in Floatlist:
    print(i, ', ', end='')

Hope that helps

P.S: This snippet code only works in Python3

According to the documentation, all objects are converted to strings (using str() function), then they are written to the stream. – Luis Alves Aug 26 '16 at 11:44

Just to print:

print(str(Floatlist).strip('[]'))
#out: 14.71525893389, 10.215953824, 14.8171645397, 10.2458542714719
