Shell script executes but does not register change to path [duplicate]

Question

I'm just trying to change this path with a simple shell script. If I type in the commands one by one it works no problem. If I put it in a shell script and run it it runs fine with no errors but does not alter the path.

#!/bin/bash
export PATH=~/Library/Python/3.4/bin:$PATH
source ~/.bash_profile

What am I doing wrong here?

If I double click on the file the output is...

    /Users/Parthenon/Desktop/ShellScripts/changeawsebpath ; exit;
Philips-MBP:~ Parthenon$ /Users/Parthenon/Desktop/ShellScripts/changeawsebpath ; exit;
logout
Saving session...
...copying shared history...
...saving history...truncating history files...
...completed.

How are you running the script and where are you expecting PATH to be changed? A script cannot alter its parent's environment, you must source for that to happen — Eric Renouf

The =~ is an conditional BRE operator vs an assignment

That only applies inside conditionals. (As an aside, the =~ operator supports (platform-dialect) EREs.)

...and not just inside conditionals in general, but specifically inside [[ ]].

@CharlesDuffy: Good point; additionally, =~ would only be recognized as an operator if surrounded by whitespace.
