Can anyone tell me how to assign a variable to a function?

Question

hello()

def hello():
print("Hello world!")
In this case how to assign a variable to hello() function

Answer 1

you want to assign the function to a variable and then invoke the function through the variable. right?
If so, after assignment, invoke function using fn(). if not, pls elaborate your problem

Answer 2

I'm not quite sure of what you meant exactly, but here's my thoughts.

If you simply want to create a variable that contains the function you can for example:

phello = hello()
print (phello)

However, if you meant to ask how to make a function that takes arguments:

def hello (response=0):
list = ["Hello World", "Hai there", "Greetings"]
try:
print(list[response])
except IndexError:
print("List doesn't contain that response!")

If no arguments are given:
hello ()
# Same as hello (response=0)
# Prints "Hello World"

But with arguments, prints the specified line

Answer 3

fn=hello
