Question

I was having trouble on how to write out my function, so that when more than one character is entered, it prints out the statement that the delimeter is too long. and returns the value none.But I don’t know how to do it. New to python and it would be a great help with some information. thanks in advance
this what I have done.

def my_split(_,_):
    my_sep = input("seperator: ")
    my_str = input("sentence: ")



def main():
    #your main program here
    print("Enter a string to be split: ")
    print("Enter the delimiter character: ") 
    print("the result is: ")


for(my_sep):
    if(my_sep <1):
    print(" the delimeter is too long.")

return None

print("enter a string to be split: ")
print("enter the delimeter character: ")
print(" the result is: ")



main()

if len(my_sep) > 1:
    print(" the delimiter is too long")
    return None

But it’s not clear where you want to put this in your code. What function are you trying to return None from? I think you want something like this:

def main():
    #your main program here
    my_str = input("Enter a string to be split: ")
    my_sep = input("Enter the delimiter character: ") 
    if len(my_sep) > 1:
        print(" the delimeter is too long.")
        return None
    result = # do the actual splitting code here
    return result

result = main()
print("the result is:", result)

Having filled in the # do the actual splitting code here, here’s what happens when I run this twice:

Enter a string to be split: Hello, World
Enter the delimiter character: ,
 the result is: ['Hello', ' World']

Enter a string to be split: Hello, World
Enter the delimiter character: lo
 the delimiter is too long.
 the result is: None
