The Python TypeError: unhashable type: 'dict' usually occurs when trying to hash a dictionary, which is an unhashable object. For example, using a dictionary as a key in another dictionary will cause this error. This is because dictionaries only accept hashable data types as a key. Only immutable objects such as strings, integers and tuples are hashable since they have a single unique value that never changes.
The Python TypeError: 'int' object is not iterable is an exception that occurs when trying to loop through an integer value. In Python, looping through an object requires the object to be “iterable”. Since integers are not iterable objects, looping over an integer raises the TypeError: 'int' object is not iterable exception.
Python Flask is a popular framework for building web applications and APIs in Python. It provides developers with a quick and easy way to create RESTful APIs that can be used by other software applications. Flask is lightweight and requires minimal setup, making it a great choice for building small to medium-sized APIs. This makes Flask an ideal choice for developers looking to build robust and scalable APIs in Python. This example will review how to create a simple rest API Flask tutorial.
Discover the power of configuration files in Python and learn how to work with YAML and INI file formats. From understanding the benefits of configuration files to comparing YAML and INI, this article is your one-stop guide for mastering configuration file management in Python.
There are several types of errors that can occur in Python. Each type indicates a different kind of problem in the code, and comprehending these error types is crucial in creating effective Python applications. The most common types of errors you'll encounter in Python are syntax errors, runtime errors, logical errors, name errors, type errors, index errors, and attribute errors. Let's go through each with examples.
The list and dictionary are the data structures that captivates data. In Dictionary, data is stored as key-value pairs, while in List, heterogeneous data types are stored. Python lists are converted into dictionaries here. As lists are ordered, and dictionaries are unordered, results can differ based on the order of inputs. Python collections encompass objects like lists and dictionaries. They enable you to hold numerous values equivalent to a specific data structure.
As you know, computers totally depend on program code to function properly. There are so many programming languages available that helps developers create applications. Python is one of the high-level, interpreted and general-purpose programming languages that is easy to use, comprehensive and powerful. In 1991, Guido van Rossum (referred to its father) developed the Python programming language.
In Python, a ZeroDivisionError is raised when a division or modulo operation is attempted with a denominator or divisor of 0.
The Python RecursionError is an exception that occurs when the maximum recursion depth is exceeded. This typically occurs when a function calls itself recursively, and the recursion doesn't have a proper stopping condition (base case).
In this article, you'll learn how to use Selenium with Python for automated testing. You will run a variety of tests on a sample website to get a fundamental understanding of automated testing with these tools.
