I guess you are trying to put that function in the interpreter namespace for other uses.

The function has a useless line and looks as though you want Python version 2.x.x and the print STATEMENT.
If you require version 3.x.x then you need the print FUNCTION and the end=" " _flag_.
Code:
#!/usr/bin/python2.7
mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    for objects in mylist:
        objects = objects.replace('hello', "hi")
        # Note the comma below.
        print objects ,

printWithoutNewlines()

OSX 10.13.4, default bash terminal calling python2.7.

hi you are so cool
AMIGA:barrywalker~/Desktop/Code/Python> _


thank you. i intended to put the following in my original code:

Code:
printWithoutNewlines()

but it looks like its not part of what i copied and pasted.

another problem im having is, before and after implementing your suggested change, i have been unable to put the output of the called function into a variable.

My original code:

Code:
#!/usr/bin/python2.7
mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    for objects in mylist:
        objects = objects.replace('hello', "hi")
        print objects

functionsOutput = printWithoutNewlines()


when I run the script, even though Im not printing out the output of "functionOutput", i still see the output.

how can i keep the results of the printWithoutNewlines function in the "functionOutput" variable without it being outputted out to the screen?

and how can I do a replacement on the content of the functionOutput variable?

here is what i have tried:

# note that im removed the comma you recommended. i did that on purpose.

Code:
#!/usr/bin/python2.7
mylist = [ "hello", "you", "are", "so", "cool" ]

def printWithoutNewlines():
    for objects in mylist:
        objects = objects.replace('hello', "hi")
        print objects

functionsOutput = printWithoutNewlines()
functionsOutput.replace('\n', ' ')

what I'm intending to do with the above code is to run the defined function, then, remove the new lines from the output of the function.

When I run the above code, I get this error:

Code:
hi
you
are
so
cool
Traceback (most recent call last):
  File "./vego.py", line 10, in <module>
    functionsOutput.replace('\n', ' ')
AttributeError: 'NoneType' object has no attribute 'replace'
