Functions and the various types of arguments they can take

This code snippet is about functions, its parameters and the various types of arguments a function can take.

def funct():
    print("I am a function that takes no value as input.")

def country(countryname="Pakistan"): #parameter with default value
    print("The name of my country is", countryname)

def greet(fname, lname): # fuction takes NMT and NLT 2 parameters
    print("Good evening", fname, lname)
    
def person(*args): # accepts variable number of positional arguments
    print(args) # returns result with quotes, commas and brackets
    print(*args) # returns result without quotes, commas and brackets
    print(len(args)) # returns number of arguments given
    print(type(args)) # returns type of data which is tuple
    
def personData(**kwargs): # accepts variable number of keyword arguments
    print(kwargs) # returns result with quotes, commas and brackets
    print(*kwargs) # returns only keys (without quotes, commas and brackets)
    print(len(kwargs)) # returns number of keyword arguments given
    print(type(kwargs)) # returns type of data which is dict here

# calling a function
funct()
print("\n")
# Function with default values, if value supplied default value is overrided
country() # returns default value
country("India") # returns india as country name
print("\n")
# positional arguments vs. keyword arguments
greet("abdur", "rehman") # positional arguments: order matters
greet(lname="rehman", fname="abdur") # keyword arguments: order doesn't matter
print("\n")
# functions that can take variable number of arguments
person("abdur", 35, "pharmacist", "pythonista", "runner", "vegetarian")
print("\n")
personData(name="abdur", age=35, profession="pharmacist", passion="pythonista")
print("\n")
