Question

### Code Explanation: String Formatting in Python

This image demonstrates the use of Python’s string formatting by showing a code snippet and its output.

#### Code:

```python
price = 9
num = 2
total = num * price
print('{2} tacos at ${2} each costs ${0}.'.format(total, price, num))
```

#### Breakdown:

1. **Variables:**
- `price = 9`: The cost of one taco.
- `num = 2`: The number of tacos.
- `total = num * price`: The total cost calculated by multiplying the number of tacos by the price of each taco.

2. **Print Statement:**
- The `print` statement uses curly braces `{}` as placeholders for variable values.
- Inside the `format` method, the variables are placed in order `(total, price, num)`.
- The numbers inside the curly braces `{}` correspond to the index position of each variable in the `format` method.

3. **Replacement Field Order:**
- `{2}` corresponds to `num` (number of tacos).
- `{2}` again corresponds to `price` (price per taco).
- `{0}` corresponds to `total` (total cost).

#### Output:
- Based on the provided field order in the `print` statement, the output will be:
```
2 tacos at $9 each costs $18.
```

The dropdown for selecting replacement fields highlights the correct indices needed to map variables accurately within the statement.

For this portion of the lab design the solution in the following manner: Create a table using a two-dimensional list that stores a Fahrenheit temperature and the equivalent Celsius temperature. Use the following range of Fahrenheit temperatures:Starting at -10 through 100 in increments of 10. Thus, the Fahrenheit temperatures will be:-10, 0, 10, 20, 30, 40, 50…and so on.Display the contents of the list.Similarly create tables/lists for the following, starting at 0 through 100 in increments of 10:Miles to kilometersGallons to litersPounds to kilogramsInches to centimetersDisplay the contents of each listSave the program as firstname_lastname_Lab7a.py where you will replace firstname and lastname with your actual first and last name.
