Python is an object-oriented programming language. It means almost everything is an object. When becoming a Python developer, it’s crucial to learn what is a Python class and how to use it to create those objects. A Python class is a blueprint for creating objects. For example, here is a simple class Person, that has […]

The most convenient way to merge two dictionaries in Python is by using the dict.update() method: This code merges dict1 at the end of dict2. Notice that it doesn’t create a new dictionary. This approach works with Python 2 and Python 3, so it’s the “safest bet” when merging two dictionaries. Besides, there are other

Python list is a common data type used to store multiple values for easy access. Sometimes, you may want to clear Python lists either by removing all the elements or removing elements one by one. This is a comprehensive guide to clearing a list in Python in 4 different ways. The short answer: To clear

To access all values in a dictionary in Python, call the values() method. For example: Or if you want to get a single value, use the square bracket [] access operator: In case you’re unsure whether the value exists, it makes more sense to use the dict.get() method to access the values. This prevents the

To end a Python program, press one of the following key combos depending on your system: This stops your program from running. How to End the Interactive Python Command-Line Session To leave the interactive Python command-line session, press: Or run the exit() function in your session: How to Terminate a Python Script If you need

Here is a list of 10+ Python tricks and tips you can use to write cleaner code. I hope you enjoy it. One-Liner If-Else in Python Sometimes when an if-else expression is simple enough, it might actually be cleaner to write it as a one-liner: But be careful not to overdo this. It can make

A loop is a programming structure that repeats a set of instructions until a condition is met. You can use loops to for example iterate over a list of values, accumulate sums, repeat actions, and so on. In Python, you can use for and while loops to achieve the looping behavior. For example, here is

In Python, everything is an object. But each object represents some particular data type, such as an integer, string, or float. To check the type of an object in Python, use the built-in type() function. Here are some examples of checking data types of different Python objects: This quick yet comprehensive guide teaches you the

To add elements to a list in Python, use the append() method: For example: Output: To add multiple elements to a list, use the built-in extend() method: For example: Output: This is a comprehensive guide to adding to lists in Python. Besides the quick answer above, you’ll learn different methods of how to add values

To copy a file in Python, use the shutil module’s copyfile() function. This piece of code copies the contents of the file src to a destination file dst. Both src and dst are strings that represent the names of the files (or rather, paths to the files). If a file dst does not exist, a
