What is The Difference?

@PythonPr The second option. In line 3. There is no 'comma ' on the right hand side of the code that separate a from b. That is one of the differences.

@PythonPr option A : 20 option B : if it’s space - Syntax Error if it’s a dot - Attribute Error

@PythonPr Comma is missing 🙃

@PythonPr a, b = b, a → swaps values (valid syntax, a becomes 20) a . b = b, a → invalid (tries to access attribute b of a, causes error)

@PythonPr Difference is comma

@PythonPr a, b. And a. b

@PythonPr SyntaxError ... .@PythonPr

@PythonPr There is no difference, Python sucks !
