Let me fix that for you: /s/approach/bad idea/ All you have done is replace one anti-pattern (assignment as an expression) with another (use of global variables). Your approach needs to have the name of the variable hard-coded, if you have three such variables you have to write three functions, you can't use local variables, and it has all the disadvantages of global state. And you don't even save any lines! Instead of a one-liner, you have six lines! > x = None > def assign_to_x(val): > global x > x = val > return val [...] > if assign_to_x(a(b,c)) == 'TRUE': > print(x) Just because a programming language allows something doesn't make it a good idea. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
