How To Call A Dictionary In A Function Python

Python is a programming language that is widely used for web development, data analysis, artificial intelligence, and more.

One of the most important features of Python is the capability of creating and manipulating dictionaries.

Dictionaries can be used to store and retrieve data in a structured and organized way. In this tutorial, we will show you how to call a dictionary in a function in Python.

Steps

1. First, create a dictionary that you want to call in a function.

1
my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}

2. Next, create a function that takes a dictionary as an argument.

1
2
def my_function(dictionary):
    # do something with the dictionary

3. Inside the function, you can access the dictionary using the dictionary parameter.

1

def my_function(dictionary):
    for key in dictionary:
        value = dictionary[key]
        print(key, value)

4. You can also modify the dictionary inside the function.

1
2
3
def my_function(dictionary):
    dictionary['key1'] = 'new value'
    return dictionary

5. Call the function and pass the dictionary as an argument.

1
2
my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
result = my_function(my_dict)

6. You can now access the modified dictionary by using the result variable.

1
print(result)

my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
 
def my_function(dictionary):
    for key in dictionary:
        value = dictionary[key]
        print(key, value)
    dictionary['key1'] = 'new value'
    return dictionary
 
result = my_function(my_dict)
print(result)

This will output:

{'key1': 'new value', 'key2': 'value2', 'key3': 'value3'}

Conclusion

Calling a dictionary in a function is a simple process that can help you organize your code and improve its readability. By following these steps, you can easily create functions that accept dictionaries as arguments and modify them as needed.
