In my data science project, I had to perform string slicing, where I needed to extract the domain part of the URLs in the dataset. For that, I applied the slicing concepts using Python’s slicing operator. In this tutorial, I have explained string slicing in Python in detail, using sever...
String slicing can accept a third parameter in addition to two index numbers. The third parameter specifies thestride, which refers to how many characters to move forward after the first character is retrieved from the string. So far, we have omitted the stride parameter, and Python defaults to...
NumPy stands for numeric python. This is used for computation in python; it is a computational package; we use this NumPy library to work efficiently with an array in python. NumPy provides us fast access to array elements. By the use of NumPy, we can perform computation on a homogenous n...

A side note: Although the above solution works, when adding to the end of a list, check out the methods aList.append() or aList.extend(). + and += can also be used.Python 3 documentation SUMMARY Slicing is a way of getting subsets of data structures. The basic notation is: ...
While it works, you may have noticed that.split()adds an empty string when the text ends with a final newline. This may not always be what you want. Additionally, splittling text into lines is a very common text processing task. Therefore, Python provides a dedicated string method called...
In short, there are so many different ways to copy a list. In this article alone, we share eight solutions. If you’re looking for something safe, use the copy method (i.e. my_list.copy()). Otherwise, feel free to try slicing (i.e. my_list[:]) or the list constructor (i.e...
