How to split a string in Python

One of the everyday operations when dealing with strings is to divide a string using a given delimiter into an array of substrings. We will explore how to break a string in Python in this post. .split() function: Strings are depicted as it has immutable property in Python. The a class contains a variety of string methods to manage the string. The .split() method returns a delimiter-separated list of substrates. The following syntax is required: a.split(xyz=None, maxsplit =-1) The boundary can be a character or character set, not a regular expression. In this example, we divide the string a using the comma (,): a = ‘John,Harry,Ricky’s.split(‘,’) The outcome is a string list: [‘John’, ‘Harry’, ‘Ricky’] As a delimiter may also use a series of characters: S = ‘John: :Harry: :Ricky’s.split(‘: :’) [‘John’, ‘Harry’ and ‘Ricky’] If Max split is defined, the number of splits will be reduced. There is no limit on the number of splits, if not stated or -1. s = ‘John; Harry; Ricky’s.split(‘;’, 1) The maxsplit+1 element in the result list will be maximized: [‘John,’ ‘Harry; Ricky’] If the xyz is not defined or Null, the string will be split as a delimiter using whitespace. As a…

How to Install Python Pip on Ubuntu 20.04

If Python is still new to you, Python is a high-level programming language oriented towards objects that have become increasingly popular over the years. Python is commonly used in software, device management, analyzing scientific and numeric data, and much more. It is possible to install either Python 2 or Python 3 on Ubuntu 20.04. With Ubuntu 20.04, though, Python 3 is the default version. PIP is a software tool that allows you to install different packages of Python on your device. Packages can be installed from the PyPI Python Package index repository and other index repositories into your framework with the PIP tool’s help. It is strongly recommended to install the module’s dev package with the apt tool when installing a global Python module. They are checked to function correctly on Ubuntu systems. The prefix for Python 3 packages is python3- and the prefix for Python 2 packages is python2-. Using Pip to globally install a module only if no deb package exists for that module. You prefer to use pips only in a virtual world. For a particular project, Python Virtual Environments allows you to install Python modules in an isolated area rather than installed globally. This way, you…

How to Find the Length of a List in Python

Lists are one of the most commonly used data types in Python and store collections of the same kind. In this article, we will see how to find the length of a list. len() Function If you want to find the length of the given object, then in Python, there is a built-in function len(), giving you the length of the given object (object means a list, tuple, string, dictionary, etc.) The syntax of the len() function is as follows: len(list) The function allows only one argument. The declared value is an integer that is the number of elements in the list. Here is an example: capitals = [‘Tokyo’, ‘Sofia’, ‘India’, ‘Budapest’, ‘America’] list_len = len(capitals) print(“The list has {0} elements.”.format(list_len)) Output: The list has 5 elements. Using Loop The another way to find the length of a list is to use them for a loop. This works by fixing up a counter and looping through all the elements of the list. On each repetition, the current value of the counter variable is incremented by one. With the help of the following code, the snippet will get an idea of finding the length of an object using the loop. capitals…

How to Convert String into Integer in Python

Objects can be any kind of data type in Python, i.e. integer and string. Sometimes, you will need to convert one data form to another while writing Python code. For example, it needs to be transformed into an integer to perform a math operation on a number represented as a string. Here’s how to convert a string in Python to an integer. int() function in Python The built-in function int() returns an integer decimal object from a given number or String. It takes the form below: int(a, base=10) Two arguments are accepted by the function: a – The number or String to be transformed to an integer. base – Reflects the first argument’s numeral scheme. It can have a value between 0 and 2–36. It is optional to render this statement. The default base is always 10 if no base is defined (decimal integer). Integers are usually expressed in hexadecimal format i.e., base 16, decimal has base 10, octal has base 8, and binary has base 2. If the given string cannot be interpreted as an integer, the ValueError exception is executed by the function. Converting a String to Integer in Python A ‘string’ is a list of characters declared…

How to Check Python Version

Python is one of the most successful programming languages in the world. It is used to develop websites, write scripts, machine learning, analyze data, and many more. This article explains how to check what Python version is installed on your operating system working the command line. This can be beneficial when installing applications that require a particular version of python. We will also explain to you how to programmatically determine what Python version is installed on the system where the Python script is running. For example, when writing Python scripts, you will require determining whether the script supports python’s version on the user’s machine. Python Versioning Python uses semantic versioning. Production-ready releases are versioned in the following scheme: MAJOR.MINOR.MICRO For example, in Python 3.6.8, 3 is a major version, 6 is a minor version, and 8 is a micro version.  MAJOR – a python, has two major versions that are not fully cooperative: Python 2 and Python 3. For example, 3.5.7, 3.7.2, and 3.8.0 are all part of the Python 3 major version. Minor: These announcements are bringing new features and roles. For example, 3.6.6, 3.6.7, and 3.6.8 are all part of the Python 3.6 minor version. Micro: The new micro versions include…
