# Example of checking data types using the type() function in Python

# Define variables of different data types
student_name = "Jordan"    # String
student_name_type = type(student_name)

age = 20                # Integer
age_type = type(age)

average_grade = 3.7     # Float
average_grade_type = type(average_grade)

is_enrolled = True      # Boolean
is_enrolled_type = type(is_enrolled)

courses = ["Computer Science", "Mathematics", "Physics"]  # List
courses_type = type(courses)

# Print the data type of each variable
print("student_name type:", student_name_type)  # <class 'str'>

print("age type:", age_type)                    # <class 'int'>

print("average_grade type:", average_grade_type)# <class 'float'>

print("is_enrolled type:", is_enrolled_type)    # <class 'bool'>

print("courses type:", courses_type)            # <class 'list'>

# How to Check Variable and Value Types

The `type()` function is used to check the type of a variable or value.

<br />

## How to Use the type() Function

The `type()` function returns the data type of a variable or value passed inside the parentheses.

```python title="Using the type() Function"
number = 10           # Assign integer 10 to variable number

print(type(number))   # <class 'int'> : Integer type


text = "Python Programming" # Assign string to variable text

print(type(text))     # <class 'str'> : String type
```

<br />

## Checking Types

The `type()` function works with both built-in and user-defined data types in Python.

```python title="Checking Various Data Types"
is_active = True

print(type(is_active))  # <class 'bool'> : Boolean type


my_list = [1, 2, 3]

print(type(my_list))    # <class 'list'> : List type


my_dict = {"key": "value"}

print(type(my_dict))    # <class 'dict'> : Dictionary type
```

The `type()` function is used to check the data type of a variable or value. For example, `type(10)` returns `<class 'int'>`, indicating it's an integer.
