This Python program has a problem! See if you can find and fix it. It should ultimately print:

Question

I have played the kazoo since I was 7 years old.

instrument = "kazoo"
age = 7

print("I have played the + instrument + since I was + age + years old.")

Answer 1

The problem with your Python program is that the string concatenation is incorrectly formatted. You are attempting to use string concatenation with +, but you are doing it inside a string, which will not produce the desired output. Instead, you can use an f-string for better readability or traditional string formatting methods.

Here are two ways to fix the program:

Using f-strings (Python 3.6+)

instrument = "kazoo"
age = 7

print(f"I have played the {instrument} since I was {age} years old.")

Using the format() method

instrument = "kazoo"
age = 7

print("I have played the {} since I was {} years old.".format(instrument, age))

Using the old-style formatting operator %

instrument = "kazoo"
age = 7

print("I have played the %s since I was %d years old." % (instrument, age))

All three of these approaches will produce the intended output:

I have played the kazoo since I was 7 years old.
