![]() The map() function is a built-in function in Python that applies a function to all the elements of an iterable (such as a list). Next, we pass this list and the int() function to another function called map(). Suppose marks = '1, 2, 3, 4', the split() method splits the string into the list. In our code above, we pass ',' as the delimiter. This method splits a string into a list, using the argument as a delimiter. Next, on line 14, we do a number of things.įirst, we use marks to call the split() method for strings. If the user enters -1, we use the break statement on line 10 to exit the while loop.Įlse, we proceed to line 12 where we prompt users to enter the class marks, and assign the input (which is a string) to a variable called marks. On line 7, we prompt users to enter the class name or -1 to quit. Next, we use a while True loop to repeatedly prompt users for input. Inside the function, we declare an empty dictionary called result. In the suggested solution above, we first define a function called getMarks() on line 1. Result = list(map(int, marks.split(','))) Marks = input('Enter Marks, Separated by Commas: ') Note that it does not do any changes in the dictionary itself but returns a string variant.A Python dictionary of lists refers to a dictionary that consists of lists as values.įor instance, if dict1 = ĬlassName = input('Enter Class Name or -1 to Quit: ') 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. 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. When converting dict into strings in Python, the dictionary's curly brackets are also converted to be a part of the strings. 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. 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. 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. Its key-value format makes it easier to map data. 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. ![]() Python offers a variety of data types for storing values in various formats, including strings, dictionaries, lists, and more.
