The parameter font had been given a default value, that is, TNR. In the last line of the above code, we have passed only two parameters to the function, that is, the values for width and height parameters. However, after calling the function, it returned the values for the three parameters. This means for a parameter with default, we don’t need to specify its value or even mention it when calling the function.

However, it’s still possible for you to specify the value for the parameter during function call. You can specify a different value to what had been specified as the default and you will get the new one as value of the parameter. Example:

#! usr bin/python3

def windowFunction(width,height,font='TNR'):

# printing everything

print(width,height,font)

windowFunction(245,278,'GEO')

The program outputs this:
