Jannik Müller thanks yes it helped.

Answer 3

Oma Falk Ich schreibe es jetzt einfach mal auf Deutsch, weil es etwas schneller geht: Lokale Variablen sind Variablen, die wieder gelöscht werden, wenn die Funktion, in der sie definiert wurden, durchgelaufen ist. Globale Variablen sind Variablen, die so lange wie der Prozess des Programms selbst erhalten bleiben. (Außer man löscht sie)
Variablen, die außerhalb einer Funktion deklariert werden, sind standardmäßig global, und Variablen, die in einer Funktion deklariert werden, sind standardmäßig lokal.
Wenn man eine globale Variable in einer Funktion deklarieren / weiterverwenden will, dann kann man das mit "global <Name>" machen.
Ich hoffe, das hat geholfen.

Answer 4

translation
Oma Falk I just write it in German because it is a bit faster: Local variables are variables that are deleted again when the function in which they were defined has run through. Global variables are variables that remain as long as the process of the program itself. (Unless you delete them) Variables that are declared outside of a function are global by default, and variables that are declared in a function are local by default. If you want to declare / continue to use a global variable in a function, you can with "global <name>". I hope that helped.

Answer 5

Jannik Müller TheWh¡teCat 🇧🇬
why globals???

Answer 6

haaaaaaarg
locals are the locals of dict comprehension which creates a closure😱😱😱

Answer 7

I think you have to replace locals() with globals(), because the variables were not declared in a function.

Answer 8

I want to understand one thing In below program, Can't we update globals() outside the comprehension?

Could you people help?

basically I want to understand the trick inside below function,

def func(args):
[*map(globals().update, [{a: val(a)} for a in args.split()])]
