tutorial on explicit type conversion in python (part 1)

introduction
in python, type conversion refers to the process of converting data from one type to another. there are two main types of type conversion:

1. **implicit type conversion**: automatically handled by python without any user intervention.
2. **explicit type conversion**: requires the user to specify the type conversion.

this tutorial will focus on **explicit type conversion**, where you manually convert one data type to another using built-in functions.

why use explicit type conversion?
explicit type conversion is useful when you need to ensure that your data is in the correct format for certain operations. for example, if you want to perform arithmetic operations on strings that represent numbers, you'll need to convert those strings to integers or floats.

common functions for explicit type conversion

here are some commonly used functions in python for explicit type conversion:

1. **int()**: converts a value to an integer.
2. **float()**: converts a value to a float.
3. **str()**: converts a value to a string.
4. **list()**: converts an iterable (like a string or tuple) to a list.
5. **tuple()**: converts an iterable to a tuple.
6. **set()**: converts an iterable to a set.

examples of explicit type conversion

1. converting to integer

you can convert various data types to an integer using the `int()` function.

```python
example: converting a float to an integer
num_float = 3.14
num_int = int(num_float)
print(f"the integer value of {num_float} is {num_int}")

example: converting a string to an integer
num_str = "42"
num_int = int(num_str)
print(f"the integer value of '{num_str}' is {num_int}")
```

output:
```
the integer value of 3.14 is 3
the integer value of '42' is 42
```

2. converting to float

you can convert integers and strings to floats using the `float()` function.

```python
example: converting an integer to a float
num_int = 5
num_float = float(num_int)
print(f"the flo ...
