The above code, copy/pasted to a file, and run from the command-line
gives the following output:
Enter Numbers to add to the sum.
Enter 0 to quit.
Current Sum: 0
Number? 1
Current Sum: 1
Number? 2
Current Sum: 3
Number? 3
Current Sum: 6
Number? 4
Current Sum: 10
Number? 0
Total Sum = 10

The syntax error seems to be the space between the '!' and the '='.
'!=' means 'does not equal'
'! =' doesn't mean anything, thus, the syntax error.
When you're beginning, you'll make plenty of errors like that.
Stop and read the error carefully, then look at the code closely.
As you gain experience, you'll learn to see those nit-picky syntax errors.
It doesn't matter which computer programming language you start out with,
each one has a specific syntax that must be followed, or you'll get syntax
errors. Python is very friendly, and the error messages it gives you are
much more helpful than other languages.
Happy Programming!
