Question

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

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+)
```python
instrument = "kazoo"
age = 7

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

### Using the `format()` method
```python
instrument = "kazoo"
age = 7

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

### Using the old-style formatting operator `%`
```python
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.
```
