Once we have defined a function, we can call it?

53. Once we have defined a function, we can call it?

1. True
2. False

Answer: A) True

Explanation:

Once a function has been defined, it can be called from another function, a program, or even from the Python prompt itself. To call a function, we simply type the name of the function followed by the appropriate parameters into the command line.

For example-

def user_name(name):
    # This function greets to user 
    # to put name
    print("Hello, " + name + ".")

user_name("Amit")	# Amit passed as function argument

# Output: Hello, Amit.
