First of all, the format specifiers (i.e, ":d") are completely optional
if you just care about the string representation of an object.
Secondly, I certainly hope that such code never passes code review
anywhere. Properly cleaning this up to
a = f(x,n)
b = g(x,n)
print(f"a={a}, b={b}")
is much more readable then the old-style
print("a=%d, b=%d" % (a, b))
or even the .format-style
print("a={}, b={}".format(a, b))
Also, format strings have the best performance for string interpolation
in python which is a non-bikeshed argument for them.
