Passing variable to another function

[JonnyDriller]

All I'm trying to do here is give the variable more scope without using the global function.
Sorry guys I thought I could solve this. At first I just did as you asked Michael. Removed the 2 function calls and placed the function inside the other. As I mentioned - this caused it to print:

Mylocation
Mylocation

So I removed the "return"

And I got

Mylocation
None

After a series of attempts my last one is below
This weirdly prints

Mylocationfoo
Mylocationfoo

I though it would print

Mylocationfoo
Mylocation

I thought only the second one was going to have the foo
def dataread():
    test_file = open('Database.txt', 'r')
    test_lines = test_file.readlines()
    test_file.close()
    #Print line
    liner = (test_lines[1])
 
    colon = liner.find(":")
    semi = liner.find(";")
    comma = liner.find(",")
    length = len(liner)
 
    name = (liner[colon+1:semi])
    location = (liner[semi+1:comma])
    gps = (liner[comma+1:length])
 
    htmlwr(location)
    return location
 
 
def htmlwr(location):
   Tester = location + "foo"
   print(tester)
 

htmlwr(dataeread())

If I remove the "return value" from this one it prints

Mylocationfoo
Error

It's as if the things looping inside itself. Which I'm sure might be a useful trait at some point. But not with this

Lastly I tried to switch the functions

dataeread(htmlwr())

But it gave me a position error
