What is the difference between the function func and its call func() in Python?

func is the name of the function (the function object in memory).

func() is a call to the function, executing its code.

	func	func()
Object type	Function	Result of function execution
Action	Reference to the function object	Executing the function code
Result	The function object itself	The value returned by the function (None if no explicit return)

# Example 1: Using func as a function object
def greet(name):
    return f"Hello, {name}!"

my_function = greet # my_function now references the same function object as greet
print(type(greet))
print(type(my_function))

# Example 2: Calling the function func()
result = greet("World")
print(result)

# Example 3: Usage difference
def add(a, b):
    return a + b

print(add)     # Prints the function object: <function add at ...>
print(add(2, 3)) # Calls the function and prints the result: 5
