In this lecture, we are discussing types of arguments in python :
-- formal argument
-- actual argument
Actual arguments have 4 types:
1)position
2)keyword
3)default
4)variable length argument
Position argument:
-- During a function call, values passed through arguments should be in the order of parameters in the function definition. This is called positional arguments.
e.g
def person(name,age):
print(name)
print(age)
add(5,6)
keyword argument:
-- During a function call, values passed through arguments don’t need to be in the order of parameters in the function definition. Keyword arguments can achieve this.
-- All the keyword arguments should match the parameters in the function definition.
e.g
person(age=28,name='navin')
default argument:
-- Default arguments are values that are provided while defining functions.
-- The assignment operator = is used to assign a default value to the argument.
-- Default arguments become optional during the function calls.
-- If we provide a value to the default arguments during function calls, it overrides the default value.
-- The function can have any number of default arguments.
-- Default arguments should follow non-default arguments.
e.g
def person(name,age=28):
print(name)
print(age)
person('navin')
variable length argument:
-- if you want to pass multiple value in a function call we can use variable length argument
def sum(a,*b):
print(a)
print(b)
c=a
for i in b:
c=c+i
print(c)
sum(5,6,34,78)
