Let us suppose you wish to write a Python function that returns the square of a number like so: defsquare(x):return(x*x)print(square(5)) The output will be: 25 You can also write a function to compute cubes like
In this tutorial, I will explain how toconcatenate tuples in Python. As a data scientist working on a project for a US-based company, I recently encountered a situation where I needed to combine multiple tuples into a single tuple. After researching and experimenting with various methods, I ...
The Python list and tuple objects are different from the NumPy array object. When you need to get the shape of a list or a tuple, you need to use thelen()function to get the rows and columns defined in the object. A NumPy array must have the same number of values in each row or ...
Use for loop to iterate through an iterable object such as alist,set,tuple,string,dictionary, etc., or a sequence. This iteration process is done in one-line code this is the basic way to write for loop in one line. Let’s implement a one-lineforloop to iterate over Python iterable ...
However, as a data scientist, you’ll constantly need to write your own functions to solve problems that your data poses to you. To easily run all the example code in this tutorial yourself, you can create a DataLab workbook for free that has Python pre-installed and contains all code ...
Python Create and Open a File Python has an in-built function called open() to open a file. It takes a minimum of one argument as mentioned in the below syntax. The open method returns a file object which is used to access the write, read and other in-built methods. ...
In this example, we have a list of names, and we write each name to a new line in the filenames.txt. Here is the exact output in the screenshot below: Check outHow to Iterate Through a List in Python? Method 2: Using writelines() ...
2. Sort the List of Tuples in Python You can sort a list of tuples in Python by using thesort() method, to specify the criteria for sorting, you can use thekeyparameter with value aslambdafunction that calculates the value used for sorting. Note that this method updates the original li...
In Python, there are several modes for file handling (file open modes) including: Read mode ('r'): This mode is used to read an existing file. Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the fil...
Unpacking a tuple in Python is the process by which you can extract the contents of a tuple into separate variables. There are two ways to unpack a tuple: 1. Using the assignment operator. 2. Using the destructuring (*) operator.
