Im new in Python and i am try to do recursion. why this return None, but when I return print it, it has a value
my_list = [30, 40, 50, 1000, 20, 60, 90, 100]
print(largest(my_list))
def largest(my_list):
if len(my_list) > 1:
x = my_list[len(my_list)-1]
if x is max(my_list):
return x
my_list.pop()
largest(my_list)
The code above will print None, but if I change the return function to print(x) instead of return x, like the code below:
my_list = [30, 40, 50, 1000, 20, 60, 90, 100]
largest(my_list) #This is the change
def largest(my_list):
if len(my_list) > 1:
x = my_list[len(my_list)-1]
if x is max(my_list):
return print(x) #This is the change
my_list.pop()
largest(my_list)
this will give me the right value
