hot to set optional argument python code example

Example 1: 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 2: 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]
