python optional function arguments code example

Example 1: python optional parameters

def my_func(a = 1, b = 2, c = 3):
	print(a + b + c)
    
my_func()
#OUTPUT = 6

my_func(2)
#This changes the value of a to 2
#OUTPUT = 7

my_func(c = 2)
#This changes the value of c to 2
#OUTPUT = 5

Example 2: python optional arguments

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

Example 3: python create a function with optional parameter

def some_function (self, a, b, c, d = None, e = None, f = None, g = None, h = None):
    #code

Example 4: optional argument python

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

Example 5: how to make an argument optional in python

#set the variable = to None, and then write over none if there the argument 
#is used.
async def joke(ctx, args=None):
    if args == None:
        await ctx.send('you :D')
    else:
        await ctx.send('%s is the true joke' % args)

Example 6: optional arguments python

def some_function (self, a, b, c, d = None, e = None, f = None, g = None, h = None):
    #code
