Note that it does not do any changes in the dictionary itself but returns a string variant. The str() function takes an object (since everything in Python is an object) as an input parameter and returns a string variant of that object. A dictionary in Python constitutes a group of elements in the form of key-value pairs. You can easily convert a Python dictionary to a string using the str() function. Given below are a few methods to convert dict to string in Python. 3 Ways to Convert Dict to String in Python The image gives you a better idea of indexing after conversion of the dictionary in string. Have a look at the image below to get a clear understanding: Hence, after this conversion, the opening bracket marks the beginning of the string and hence, is assigned an index = 0. For example: def drawpoint(x, y): do some magic pointfoo (3, 4) pointbar. When converting dict into strings in Python, the dictionary's curly brackets are also converted to be a part of the strings. You can convert a JSON string to python collections like lists, dictionaries using json.loads() method in python. You can unpack a list or a dictionary as function arguments using and. Now, you must be wondering why did it give '1' at string? This is because of "indexing". This confirms the conversion of dict to string in Python. Note the difference between the output when we try to access the value using keys. In Python Programming, key-value pairs are dictionary objects and ordered list are list objects. ![]() What is a Dictionary in Python?Ī dictionary is a mutable data type in Python, that stores data in the form of key-value pairs.ĭictionary = type In this article, we'll look at methods for converting a dictionary to a string in Python. As a result, dictionaries must be converted into strings and vice versa. However, dictionaries in Python do not allow duplicate keys. If you want to store a dictionary's data in a file or database, a string is a more convenient format for storage.įurthermore, if you're familiar with JSON files, you must be aware that text is one of the permitted forms for storing data in JSON. As we know, a dictionary is a collection of elements that are ordered and can be modified. Its key-value format makes it easier to map data. In this, we perform mapping values using dictionary comprehension. ![]() ![]() While programming, you will come across the problem of converting one data type to another.ĭictionary is a convenient format to store and map data. Method 1 : Using loop + dictionary comprehension This is one of the ways in which this task can be performed. Python offers a variety of data types for storing values in various formats, including strings, dictionaries, lists, and more.
