print(f"Year = ", years + f"Future value = \n", future_value)When joining a
string with a number, use an f-string otherwise, code a str() because a implicit convert of an int
to str causes a TypeError!Well...WTF! Am I not using the f-string function correctly...in the above
line of code???
There's no implicit conversion. An f-string always gives you a string.
'years' is an int, f"Future value = \n" is a str, and you can't add an
int and a str.
Maybe you meant this:
print(f"Year = {i}, Future value = {future_value}")
or this:
print(f"Year = {i + 1}, Future value = {future_value}")
These are equivalent to:
print("Year = {}, Future value = {}".format(i, future_value))
and:
print("Year = {}, Future value = {}".format(i + 1, future_value))
