what are default arguments in python code example
Example 1: how to set a default parameter in python
def my_function(num1,num2=0): #if num2 is not given, it will default it to zero
return num1 + num2
print(my_function(1,2)) #prints out 3
print(my_function(4)) #prints out 4 since num2 got defaulted to 0
Example 2: default values python
class Test:
def __init__(self, val, num = 0):
self.val = val
self.num = num
# you can write this:
t = Test(1)
print(t.num) # prints 0
# OR this
t = Test(1, 2)
print(t.num) # prints 2
