explain me something:

Question

I had to change my code because the interpreter that I was using claimed an error.
So, my code was:

A = int(input(""))
B = int(input(""))
X = A + B
print(f'X = {X}')

and I had to change the last line so my new code is:

A = int(input(""))
B = int(input(""))
X = A + B
print("X = %d" % (X))

and I wish that someone explain to me that last line because I don't get it.

Answer 1

Which python version does your interpreter use? f-strings are new to python 3.7 (or 3.6, not sure).

The last line of your second code uses a format specifier: https://pyformat.info
