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: make parameter optional python
def myfunc(a,b, *args, **kwargs):
for ar in args:
print ar
myfunc(a,b,c,d,e,f)
Example 4: 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 5: python print without optional argument
a = [0, 1, 2, 3, 4]
print(*a) # print 0 1 2 3 4
print('[' + ' '.join(map(str, a)) + ']') # print [0 1 2 3 4]
Example 6: optional arguments python
def some_function (self, a, b, c, d = None, e = None, f = None, g = None, h = None):
#code
