A string is a group of characters that can represent a single word or a complete sentence. In Python there is no need to declare variables explicitly using the datatype specifier you can directly assign them to a literal. Therefore, compared to other technologies like Java it is easy to use Python strings. For manipulating and accessing strings, Python includes several built in functions and methods. You can find these functions in a class named String. In this article, we are going to focus on how to invert the case for all letters in a string in Python. Using the ... Read More

In this article we are going to check whether the string starts with the substring or not, It is useful for checking whether the string starts with the substring, which is helpful in tasks like filtering data or validating input. In Python there are various ways to perform this check, such as startswith(), string slicing and regular expression. Let's dive into the article to learn more about them. Using python startswith() Method The Python startswith() method is used to check whether the string starts with a given substring or not. This method accepts a prefix string that you ... Read More

In this article, we are going to find out how to split at newlines in Python. In general, split means to divide or to make a group of objects divide into smaller groups. The first approach to split at NEWLINES in python is by using the inbuilt method splitlines(). It takes a multi-line string as input and it returns a separated string that is divided at the new line. It doesn’t take any parameters. The splitlines() method is an inbuilt string method and it is used only for splitting at the new lines. Example 1 In the program given below, ... Read More

While working with the strings in python, we will find the situations to break the string into parts. This is called splitting a string and is usually done based on a delimiter, this is nothing but a character or sequence of characters that separate the parts of the string. Python provides the several ways for achieving this, depending on whether the delimiter is simple string or a pattern. Let's dive into the article to learn more about splitting string by delimiter. Using python split() Method The python split() method is used to split the words in a string separated by ... Read More

Any character or group of characters that depicts horizontal or vertical space is known as whitespace. A whitespace character usually takes up space on a page even though it does not correspond to any visible mark when it is rendered. Pressing the spacebar will allow you to enter a whitespace character. On many keyboards, the Tab key can also be used to enter horizontal whitespace, although the length of the space may vary. Any spaces or tabs that follow the final non-whitespace character on the line until the newline are considered trailing whitespace. Whitespace in Python Whitespace is a type ... Read More

In python, Right-aligning the strings with space padding is a common requirement when formatting the text-based output such as reports, logs or tabular data. This can be done by using the built-in string methods. Let's dive into the article, to learn different ways to get a space-padded string with the original string right-justified in python. Using python rjust() Method The python rjust() method is used to right-align a string by padding it with a specified character on the left. Syntax Following is the syntax of python rjust() method − str.rjust(length, character) Example Let's look at the ... Read More

In this article, we are going to find out how to search a string in backward direction in Python. The first method is to use the inbuilt python String class's rindex() method. The highest index of any substring in the given string is returned by the Python string rindex() method. By highest index, we mean that if a given substring appears twice or three times in a string, the rindex() method will return the index of the substring's rightmost or final occurrence. The main disadvantage of this function is that it throws an exception if the string contains no substrings. ... Read More

In Python, working with strings is a common task in data processing and text analysis. The common operation is finding the last occurrence of a specific substring. It is useful in situations like extracting the domain names or locating the repeated elements in logs. Python provides several methods to accomplish this; the most commonly used are − Python rfind() Method Python rindex() Method Using python rfind() Method The Python rfind() method is used to find the last occurrence of the substring in the given string; if not found, ...

A string is a group of characters that may be used to represent a single word or an entire phrase. In Python strings not require explicit declaration and may be defined with or without a specifier therefore, it is easy to use them. Python has various built in functions and methods for manipulating and accessing strings. Because everything in Python is an object, a string is an object of the String class, which has several methods. In this article, we are going to focus on replacing all occurrences of a string with another string in python. Using the replace() method ... Read More

A string is a collection of characters that can represent a single word or a whole sentence. Unlike Java there is no need to declare Python strings explicitly we can directly assign string value to a literal. For manipulating and accessing strings, Python include several built in functions and methods. A string is an object of the String class, which contains multiple methods because everything in Python is an object. In this article, we'll look at how to retrieve the minimum alphabetical character from a string in Python. The min() function The most common solution for this problem is to ... Read More
