expressions, check out How to Use Generators and yield in Python. Map The built-in functionmap() takes a function as a first argument and applies it to each of the elements of its second, an iterable. Examples
NumPy library is used in python to create one or more dimensional arrays. The unique() function is one of this library's useful functions to find out the unique values of an array and return the sorted unique values. How to use the python NumPy unique()
In thisPythontutorial, I will explain what thenp.argsort() functionis, and how to usenp.argsort in descending order in Pythonwith some illustrative examples. To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array ...
One of the things Python does well is abstracting complexity. One example of that is the Python function. A function is a reusable set of instructions to perform a task. Functions aren’t unique to Python; in fact, they work mostly the same as in other languages. If you want to know ...
If you’re using modules, such as math or random, then make sure not to use those same names for your custom modules, functions, or objects. Otherwise, you might run into name conflicts, which can cause in unexpected behavior. The Python Package Index and pip The Python package index, al...
Let's say you find data from the web, and there is no direct way to download it, web scraping using Python is a skill you can use to extract the data into a useful form that can then be imported and used in various ways. Some of the practical applications of web scraping could be...
Create a Main Function: The primary role will be to create the blockchain, mine for a few additional blocks, and then validate the blockchain. This function checks the accuracy and functionality of your implementation. Here is an example of a simple blockchain in Python: import hashlib import...
Method 2 – Insert the INDEX and MATCH Formula to Get Unique Values From Range Steps: Select cellE5. Use this formula in the cell: =INDEX(B5:B20,MATCH(0,COUNTIF($E$4:E4,B5:B20),0)) Formula Explanation The driving force of this formula is theINDEXfunction which will perform the basi...
values()returns the count of every unique value in the list. We can use thelen()function to get the number of unique values by passing theCounterclass as the argument. Example Codes: fromcollectionsimportCounter words=["Z","V","A","Z","V"]print(Counter(words).keys())print(Counter(wo...
By itself, a function does nothing. But, when you need to use a function, you can call it, and the code within the function will be executed. In Python, there are two types of functions: user-defined and built-in. Built-in functions are functions like: print(), which prints a state...
