# Examples of handling TypeError exceptions in Python

# Variable declaration
num = 5
string = " day"

# TypeError demonstration and handling
try:
    num_string = num + string
    print("This line will not be executed")
except TypeError:
    print("You cannot directly add an integer and a string.")


print('=' * 40)

# Performing operations after correct data type conversion
try:
    # Convert the integer to a string using the str() function
    num_string = str(num) + string
    print(num_string)  # '5 day event'
except TypeError:
    print("Error occurred during type conversion")

# TypeError Due to Operations Between Different Data Types

A `TypeError` typically occurs when you try to perform arithmetic operations on incompatible data types, such as numbers and strings.

For example, adding a string (`apple`) and a number (`ten`), as shown below, will raise a `TypeError`.

```python title="TypeError Example"
ten = 10
apple = "apple"

result = apple + ten  # TypeError: unsupported operand type(s) for +: 'int' and 'str'
```

<br />

## How to Handle TypeError

To prevent a `TypeError`, ensure that data types match or are appropriately converted before performing operations.

```python title="Data Type Conversion Example"
number = 10
text = "apple"

result = str(number) + text  # '10apple'
```
