Keyword Arguments


Keyword Arguments in Python 3


Keyword arguments are related to the function calls. When you use keyword arguments in a function call, the caller identifies the arguments by the parameter name. This allows you to skip arguments or place them out of order because the Python interpreter is able to use the keywords provided to match the values with parameters.

You can also make keyword calls to the printme() function in the following ways-

#!/usr/bin/python3

# Function definition is here
def printme( str ):
    "This prints a passed string into this function"
    print (str)
    return

# Now you can call printme function
printme( str = "My string")


When the above code is executed, it produces the following result-

My string

The following example gives a clearer picture. Note that the order of parameters does not matter.



and the output is :
