But this code will produce an incorrect answer to arr = [1,1,1]. Or do I understand something wrong?

can someone explain what the *n in the format function does I'm new to python. Thank you

bealtiful

Nope, I think the first comment's correct.

You can't multiply an integer by a string, but you CAN multiply a string with an integer.

Really cool!

this is the way.

did the same lol

Amazing

gorgeous solution! Didn't know about this possibility

no he mean he use "join" method while he can do this like this

why you when to join first?

Write a function that accepts an array of 10 integers (between 0 and 9)

Amazing!!!
Although the test wasnt made to catch exceptions, it would be nice to implement one to catch errors if the input contains something other than integers and a lenght different than 10.
