Python help a newbie?

Question

Python

Good day to all, I decided to study programming from books, it turns out a little, tell me with a simple question, maybe stupid, but I don’t understand.
I write the script
a=4
b=5
c=9
print("c","-b","=",a)

Why does it give it out later like this
cb=4
I need to get an answer in numbers instead of letters

what and where I'm doing wrong how right

Answer 1

a=4
b=5
c=9

print('{2:d}-{1:d}={0:d}'.format(a, b, c))

# выведет: 9-5=4

In simple terms about formatting
{2:d} , this is the place to display the value. 2 is the position of the argument, the third will go here, c.
After the colon, format dmeans number.

Answer 2

if python is fresh, then you can use f-string:
print(f"{c}-{b}={a}")

Answer 3

Instead of "c", write str(c), respectively, the same with b.
And open at least the textbook, seriously.
