Adding Words Problem

Question

Hi, here is my code for “adding word” problem:
def concatenate(*args):
for i in range(len(args)):
print(args[i], end="-")

concatenate("I", "love", "Python", "!")

After running this code, I am getting the output like below:
I-love-Python-!-

How to remove the last - ?

TIA

Answer 1

we can use the join() function with '-' as argument.

'-'.join(...) creates a string and separates the elements of variable args by a '-' :

def concatenate(*args):
print('-'.join(args))
...

Answer 2

Try it this way, using the unpacking operator * to replace the loop and print the list elements without their enclosing brackets. Specify the separator between elements by using sep= instead of end=.

def concatenate(*args):
print(*args, sep="-")

concatenate("I", "love", "Python", "!")

Answer 3

def concatenate(*args):
print('-'.join(args))

concatenate("I", "love", "Python", "!")

OR

def concatenate(*args):
print(*args, sep='-')

concatenate("I", "love", "Python", "!")

Answer 4

Thanks all.

Answer 5

Hi Shine1Tek!
You may find the ternary operator useful in this case. You can keep adding the "-" symbol until it meets the last word.
Here's how you do it

def concatenate(*args):
for i in range(len(args)):
print(args[i], end="-" if args[i] != args[-1] else "")

concatenate("I", "love", "Python", "!")
