Why we use concatenation in python?

Question

Why add two strings together instead of just type two words.

Answer 1

string concatination is usefull when you do not know the value of the strings you add together

s = "5 + 6 = " + "11"
wouldn't be very usefull here. However, in most code, you won't know most variable. Here is an example:

x = int(input())
y = int(input())
result = x + y
s = str(x) + " + " + str(y) + " = " + str(result)
print(s)

Using string concatination, I was able to print out the complete math used without knowing any actual values.

And little shortcut for those concatinations using f strings:
s = f"{x} + {y} = {result}"

I hope this helps!
