Example 1: python arguments
import sys
print ("the script has the name %s" % (sys.argv[0])
Example 2: how to define function in python
def example(): #This defines it
print("Example.") #This is the defined commands
example() #And this is the commands being run
Example 3: python function arguments
#*args and **kwargs are normally used as arguments when calling the function.
#*args returns as tuple and **kwargs returns as dictionary.
#*args and **kwargs let you write functions with variable number of arguments in python.
def func(required,*args,**kwargs):
return f"{required} {args} {kwargs}"
func("Nagendra",5,32,2,1,23,) #output == 'Nagendra (5, 32, 2, 1, 23) {}'
func("Nagendra",5,32,2,1,23,key1="55",key2="75") #output == "Nagendra (5, 32, 2, 1, 23) {'key1': '55', 'key2': '75'}"
#Very understable example of args.
#Given n number of arguments in a function calculate its average
def average(*args):
'''
As we already know *args means collection of values in a tuple.
INPUT: arguments are given. example average(4,10,)
OUTPUT: average of two numbers (4+10)/2 == 14
'''
return sum(args)/len(args)
average(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) #output == 8.0
