Assign default value to function parameters
Adding default value to parameters
For named parameter we can provide default value. If no value is provided during the method calling the default values are used.
def hello(greeting='Hello', name='world'):
print '%s, %s!' % (greeting, name)
# ww w .j a va 2 s . c o m
hello()
hello('Greetings')
hello('Greetings', 'universe')
# To supply only the name, leaving the default value for the greeting.
hello(name='Gumby')
def fun(name, location, year=2006):
print "%s/%s/%d" % (name, location, year)
fun("Teag", "San Diego")
def fun(name, location, year=2006):
print "%s/%s/%d" % (name, location, year)
fun(location="L.A.", year=2004, name="Caleb" )
The code above generates the following result.
