What is different between this Two Codes?

Question

def get_Input():
Command = input(": ").split()
verb_word = Command[0]

if verb_word in verb_Dic:
verb = verb_Dic[verb_word]
else:
print("Unknow Verb {}".format(verb_word))
return

if len(Command) >= 2:
noun_word = Command[1]
print_Input(noun_word)
else:
print_Input("Nothing")

def print_Input(noun):
print("You said {}".format(noun))
return

verb_Dic = {"say" : say}

while True:
get_Input()

I changed this EX, But It doesn't work.

So, I Changed again Like This..

def get_Input():
Command = input(": ").split()
verb_word = Command[0]

if verb_word in verb_Dic:
verb = verb_Dic[verb_word]
else:
print("Unknow Verb {}".format(verb_word))
return

if len(Command) >= 2:
noun_word = Command[1]
verb(noun_word)
else:
verb("Nothing")

def say(noun):
print("You said {}".format(noun))
return

verb_Dic = {"say" : say}

while True:
get_Input()

and FINALLY it works.

But I can't Understand what is different between that.

need someone help..

Answer 1

Print_input was not def in first code

Answer 2
