To convert a number in scientific notation to decimal format in Python, you can use the `float()`

or `decimal.Decimal()`

function. Here are two examples:

Using `float()`

:

```
scientific_notation = '1.23e+5'
decimal_number = float(scientific_notation)
print(decimal_number)
```

Output:

`123000.0`

In this example, the `float()`

function is used to convert the scientific notation string `'1.23e+5'`

to a floating-point decimal number.

Using `decimal.Decimal()`

:

```
import decimal
scientific_notation = '1.23e+5'
decimal_number = decimal.Decimal(scientific_notation)
print(decimal_number)
```

Output:

`123000`

In this example, the `decimal.Decimal()`

function from the `decimal`

module is used to convert the scientific notation string to a `Decimal`

object. The resulting `decimal_number`

is a decimal representation of the scientific notation.

Both approaches will convert the scientific notation to decimal format. The `float()`

function is suitable for most common use cases, while the `decimal.Decimal()`

function provides higher precision and is suitable for situations where precise decimal arithmetic is required.

Make sure to replace `'1.23e+5'`

with the actual scientific notation string you want to convert. The resulting `decimal_number`

will be a decimal representation of the scientific notation.
