How can I use dictionaries in Python functions?

How can I use dictionaries in Python functions?

You can pass dictionaries as arguments to functions, allowing you to access key-value pairs inside the function.

Can you give me an example of a function that uses a dictionary?

Sure! Here's a simple example:

def print_student_info(student):
    print(f"Name: {student['name']}, Age: {student['age']}")

student = {'name': 'Alice', 'age': 20}
print_student_info(student)

What if I want to update a value in the dictionary inside the function?

You can modify the dictionary directly. For example:

def update_age(student, new_age):
    student['age'] = new_age

update_age(student, 21)
print(student)

Can I return a new dictionary from a function?

Absolutely! You can create and return a new dictionary like this:

def create_student(name, age):
    return {'name': name, 'age': age}

new_student = create_student('Bob', 22)
print(new_student)
