The aspect ratio of a plot refers to the ratio of the width to the height of the plotting area. It is a crucial parameter in data visualization as it determines the shape and proportions of the plot which directly affects how the data is visually represented. For example in a square plot the aspect ratio would be 1:1 which means the width is equal to the height. In contras if the width is twice the height then the aspect ratio would be 2:1 and the plot would be wider horizontally. The below are the effects of changing the plot’s ... Read More
Consecutive Character Maximum Difference refers to finding the maximum absolute difference between the ASCII values of consecutive characters in a string. It is used to measure the maximum "gap" or "jump" in the character sequence based on their ASCII values. In Python, each character in a string is represented internally as a Unicode code point, and the corresponding ASCII value can be obtained using the `ord()` function. The ASCII values of consecutive characters can be compared to calculate the absolute difference between them. For example, consider the string "abcdefg" − The ASCII value of 'a' is 97. The ASCII ...

Concatenation is the process of combining two or more strings, sequences, or data structures together to create a single larger entity. In the context of strings, concatenation involves joining multiple strings end-to-end to form a new, longer string. In many programming languages such as Python, the concatenation operation is typically represented using the + operator. When we use the + operator with strings, it performs string concatenation, joining the strings together in the order they appear. Example Here's an example of string concatenation in Python. string1 = "Welcome to " string2 = "Tutorialspoint!" result = string1 + string2 print(result) ... Read More
Converting a character matrix to a single string in Python means taking a 2D representation of characters such as a list of lists or a NumPy array and combining all the characters into a single string. The order of the characters in the resulting string is determined by the arrangement of characters in the matrix. In this implementation, the matrix_to_string() function takes a 2D list of characters (matrix) as input. The function first uses list comprehension to join characters in each row into individual strings. The result is a list of strings representing each row in the matrix. Next, the ... Read More
Concatenation is the process of combining two or more strings, lists, or other sequences into a single entity. It involves joining the elements of the sequences in a specific order to create a new sequence or string. In Python, concatenation can be performed on various types of sequences, including strings, lists, tuples, and more. The specific method or operator used for concatenation depends on the type of sequences being combined. Let's explore different approaches to concatenation in Python − String Concatenation When concatenating strings, the '+' operator or the str.join() method is commonly used. In the below example, the strings ... Read More
Concatenation is the process of combining two or more strings, lists, or other sequences into a single entity. It involves joining the elements of the sequences in a specific order to create a new sequence or string. In the context of strings, concatenation means appending one string to the end of another, resulting in a longer string. For example, if we have two strings, "Hello" and "World", concatenating them would produce the string "HelloWorld". The concatenation operator (+) or the str.join() method is commonly used for string concatenation in Python. Similarly, concatenation can be applied to other sequence types, such ... Read More
Python is an interpreted programming language. However, when we want to check whether Python is compiled or interpreted can be a bit confused. Let's dive into a detailed explanation to understand the inner workings of Python's execution model and how it combines aspects of compilation and interpretation. Interpreted languages are typically executed directly by an interpreter without a separate compilation step. In contrast, compiled languages go through a compilation process where the source code is translated into machine code or an intermediate representation before execution. However, Python's execution model is a blend of both interpretation and compilation. At a high ... Read More
Gradients displays the combination of two or more colors. Linear gradients are used to arrange two or more colors in linear formats like top to bottom. Radial gradients appear at center. Linear-Gradient The linear gradient is set using the background-image property. The angle is set as the first parameter. Here is the example − body { font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif; } div ... Read More
We can use a combination of percentage and em to specify the font-size of elements for better compatibility of font. This allows us to have uniform text across different browsers. Both percentage and em are relative measurements. Syntax The syntax of CSS font-size property is as follows. The below works for both the percentage and em units in place of value. Also, other length units can also be set − Selector { font-size: /*value*/ } Example The following example illustrate how CSS font-size property can be set. First, we have set the font using ...

To customize the style for the input textbox having a placeholder, we use the :placeholder-shown pseudo-class of CSS. Placeholder text is a hint for the user to understand what is to be typed in the input text field. The following examples illustrate CSS :placeholder-shown pseudo-class. Set the border for the text field The border for the text field is set using the border-color property. Place it inside the placeholder-shown pseudo-class as shown below − input:placeholder-shown { border-color: dodgerblue; } Example Let us see the example − ... Read More
