TypeError: not all arguments converted during string formatting

This error occurs when the number of arguments provided in a string formatting operation does not match the number of placeholders in the string.
For example, consider the following code:
```
name = 'Alice'
age = 25
print('My name is %s and I am %d years old.' % name)
```
In this code, the `%s` and `%d` are placeholders for the `name` and `age` variables, respectively. However, we only provided one argument (`name`) in the string formatting operation. This will result in a `TypeError` because the code expects two arguments.
To fix this error, we need to provide the correct number of arguments:
```
name = 'Alice'
age = 25
print('My name is %s and I am %d years old.' % (name, age))
```
Here, we enclosed `name` and `age` in parentheses to create a tuple with two elements that can be passed as arguments to the string formatting operation.
