I don't understand the concatenation here in this string. Please help me understand.

Question

Let's say you want to print something like "John [Smith] is a coder."
first = 'John'
last = 'Smith'
message = 'first + ' [' + last + '] is a coder'
print(message)

Answer 1

Thanks so much for solution guys.

Answer 2

What specifically?

Answer 3

The main problem is that there was a mistake with using the quotes:

# Missing a quote?
# v
'first + ' [' + last + '] is a coder'

But you might be interested in the format method, supports performing string concatenations much easier:
message = '{0} [{1}] is a coder'.format(first, last)

Answer 4

Okay I get it. What I don't quite understand is line 4 on the variable message.

Answer 5

The problem is, that between 'first +' and ' [' were not performed a string concatenation, because + was outside the string. Propably just a typing/thinking mistake

Answer 6

I don't get it because I just began. I'm really bad at coding. I shouldn't be replying. sorry.
