When a function is called, it accepts only one value per parameter. Python interpreters will raise a SyntaxError when they see something like ``++myfunction(a=1, a=2)++``, but there are other cases which will only fail at runtime:
|
|
|
|
* An argument is provided by value and position at the same time.
|
|
* Some arguments are provided via unpacking and the same argument is provided twice.
|
|
|
|
This rule raises an issue when a function is called with multiple values for the same parameter.

== Noncompliant Code Example
|
|
|
|
----
|
|
def func(a, b, c):
|
|
return a * b * c
|
|
|
|
func(6, 93, 31, c=62) # Noncompliant: argument "c" is duplicated
|
|
|
|
params = {'c':31}
|
|
func(6, 93, 31, **params) # Noncompliant: argument "c" is duplicated
|
|
func(6, 93, c=62, **params) # Noncompliant: argument "c" is duplicated

== Compliant Solution

def func(a, b, c):

return a * b * c
|

print(func(c=31, b=93, a=6)) # Compliant
