In this article, we are going to find out how can we tell if a string repeats itself in Python. The first approach is by using slicing and find(). We want to see if the string we have is made up entirely of repeats of a substring of the string. We can confirm this by looking for a rotation of the string in a pair of strings. After adding a string and checking the root string in this string, except for the last and first character, we may search for the root string. This approach doesn’t work for strings with ...

In this tutorial, we will learn to POST unchecked HTML checkboxes. To interact with a user, it is necessary to take their input or data through the website. The HTML forms are used to take input from the user. Forms are essential to take the data of the user on the website. These forms take input from the user and send data to the server using HTTP requests. There are two types of HTTP requests one is GET, and the other is POST. The POST request is the most used type because it is secure and can send a large ... Read More
In this article, we are going to find out how to get integer values from a string in Python. The first approach is by using the filter() method. We will pass the string and the method isdigit() to the filter method. Python has a built-in function called Filter(). An iterable, like a list or dictionary, can have the filter function applied to it to create a new iterator. Based on the criteria you provide, this new iterator can filter out specific elements quite well. The filter() method checks the string for digits and filters out the characters that satisfy the ...

In this tutorial, we will learn about Max parallel HTTP connections in a browser. To know more about this topic, we will first understand what parallel connections are, the reasons behind blocking and how to solve it, and the browser limitations. Parallel Connections By entirely requesting the original HTML page, the first embedded item, the second embedded object, etc., a browser may naively process each embedded object in sequence. But it moves too slowly! HTTP enables clients to establish connections and parallelly carry out numerous HTTP transactions. Parallel Connections Could Speed Up Page Loading. If composite pages with embedded objects ... Read More
In this article, we are going to find out how to scan a string for specific characters in Python. The first approach is by using the ‘in’ keyword. We can use the ‘in’ keyword for checking if a character is present in the string. If it is present in the string, True is returned otherwise, False is returned. The ‘in’ keyword is also used to iterate through a sequence in a for loop which is also used for iterating over a sequence like list, tuple and string or other iterable objects. Example 1 In the example given below, we are ... Read More
In this article, we are going to focus on checking if a string can be converted to a float in Python. The first approach is by using the float() type cast. We will write a function using exception handling and check if the given string can be converted into string, if it can be converted then True is returned, else False is returned. A floating−point number is returned by the method float() for a given number or text. It will return 0.0 as the floating−point value if no value or a blank parameter is given. Example 1 In this example, ... Read More
In this article, we are going to find out how to split a string on whitespace in Python. The first approach is by using the inbuilt method split(). This method splits the given string at our desired delimiter. The split() method accepts a parameter named as a delimiter, it specifies at what character should a string be split. So, we have to send white space as a delimiter to the split() method. This method returns the modified list that is split in white space. Example In the example given below, we are taking a string as input and we are ... Read More
In this article, we are going to focus on how to create a long multi−line string in Python. The first approach is by using triple quotes, we should add a triple quote then we can add separate line inside the quotes, the multi-line string is created. Using triple quotes in Python, it is possible to span strings across many lines. It can also be applied to lengthy code comments. Triple quotes can also contain special characters like TAB, verbatim, or NEWLINES. As the name would imply, the syntax consists of three single or double quotes placed consecutively. Example In the ... 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
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
