Question
What do these lines print?
>>> def my_function(counter=89):
>>> print("Counter: {}".format(counter))
>>>
>>> my_function(12)
Counter: 12
Counter: 89
Solution
The code you provided defines a function called my_function
that takes one argument counter
with a default value of 89. Then it calls this function with the argument 12.
Here's a step-by-step explanation:
-
def my_function(counter=89):
This line defines a function namedmy_function
that takes one argumentcounter
. If no argument is provided when the function is called,counter
will default to 89. -
print("Counter: {}".format(counter))
This line is inside the functionmy_function
. It prints the string "Counter: " followed by the value ofcounter
. The value ofcounter
is inserted into the string using theformat
method. -
my_function(12)
This line calls the functionmy_function
with the argument 12. So, when the function is called,counter
is 12, and the function prints "Counter: 12".
The lines you provided do not include a call to my_function
without an argument, so "Counter: 89" is not printed. If you were to call my_function()
without an argument, then it would print "Counter: 89", because 89 is the default value for counter
.
