Please can someone explain this to me, and how is the say function a value in the dictionary

Question

def get_input():
command = input(": ").split()
verb_word = command[0]
if verb_word in verb_dict:
verb = verb_dict[verb_word]
else:
print("Unknown verb {}". format(verb_word))
return

if len(command) >= 2:
noun_word = command[1]
print (verb(noun_word))
else:
print(verb("nothing"))

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

verb_dict = {
"say": say,
}

while True:
get_input()

Answer 1

Values in dictionaries can contain functions as well.
You defined the function say() and added it as a value in the dictionary, with the key "say". There, the key is a string and the value is a function.

When you assign say() to the parameter verb, verb stores a pointer that points to the function say()'s location. So when verb() is called, it executes say().

get_input() function takes an input and splits using spaces.
If it only has 1 argument, it will proceed to call say(" nothing").
ex: "say" outputs "You said nothing"
If it has more than 1 argument, it will call say(first_argument) and ignores the rest of the arguments.
ex: "say some thing nice" as an input will only call say("some") and ignores "thing", "nice". So the output is " You said some"
