The process of conducting mathematical operations on time values is referred to as time arithmetic. Adding or subtracting time durations, determining the difference between two-time values, or determining the average of a group of time values are a few examples of time arithmetic. Some of the applications are used to demonstrate time arithmetic such as time tracker, data analysis, and time scheduling. In Python, we have time built-in functions i.e. strptime() and divmod() that can be used to demonstrate the time arithmetic. There are two ways of time formats that are 12 hours and 24 hours. Let’s take an example ... Read More

In Python, we have a built-in function int(), timedelta(), and divmod() that can be used to get the number in the form integer and is useful for converting Miliseconds to Minutes and seconds. The milliseconds are defined by the short duration of time. The milliseconds are equal to one-thousandth of the second. When 5000 milliseconds convert into minutes the result value is 0.08 minutes and 5 seconds. For example- The photographer clicks the picture and saves it in a gallery which takes some seconds that time is preferred to be milliseconds. Syntax int() The int() function accepts the ...

Python has various internal functions like isspace(), lstrip(), and replace() are used for trimming a given string. It means it will remove the whitespace from the left side of the string. Let’s take an example to understand the trim of a string from the left side. In the given string “MICROBOX” remove the left string MI and get the result value as “CROBOX”. In the given string “synapse” remove the left string syn and get the result value as “apse”. In this article, we will learn how to develop a Python program that will trim the string from ...

Multiple files are compressed together and stored in a single file format called a zip file. There are some applications such as file management, data processing, file conversion, and backup & archive of files. In Python, we have zip in-built functions like infolist() and namelist() that can be used to Read and printing all files from a zip file. We utilize the predefined method 'namelist()' or 'infolist' to read the data within the zip folder in order to output all of the files that are currently present inside the zip file. Input // This is a zip folderOutput The ... Read More

In Python, we have some file in-built functions that can be used to count the number of lines present in the file. We will open the notepad and write some lines of text into it. Then use this file in the file handling program in Python to count the total number of lines present in the file. The ‘r’ mode is defined by reading the file's text. Syntax The following syntax is used in the example is − with open("file_name.txt", mode) The open method is used for opening a file in Python. This accepts the two parameters − ... Read More

In Python, we have file handling in-built functions like open(), write(), and close() that can be used to Append a String or Text to an Existing File. The term append is used in the program of file handling in Python. To append the text or string means that the user writes the new text to the existing file. The main purpose of adding text to an existing file means giving extra information to the existing file. Note-taking and Data collection are such applications of this program. Syntax The following syntax is used in the example is − open("file_name.txt", mode) ... Read More

In this article, we will learn how to create a Python program to delete prefix substrings from a given string. Sometimes in data, we have a prefix of multiple words of the same type and if we want to delete them then it will take a lot of time but this can be solved by giving an algorithm to it. A prefix is a group of characters that are added to the beginning. Let’s take an example to understand this. The given string variable is “My shirt color is Red” and delete the prefix variable i.e. “My”. Then, the final ... Read More

In Python, we have some built-in string functions like rstrip(), replace(), and endswith() that can be used to delete suffix from the given string. The delete suffix is termed by removing the group of characters at the end of the string. Sometimes we find errors like suffix in any data and if we want to delete it, it takes a lot of time and this can be solved by giving an algorithm to it. The end character or substring is termed a suffix. Let’s take an example to understand this − The given string variable is BRIGHTNING and after removing ... Read More

Python has various built-in functions that can be used for capitalization of the string. In this article develop a python program to perform this task using its lower() function. The lower() method converts each uppercase character in the input string to lowercase before returning the lowercased strings. It returns the original string if the given string contains no uppercase letters. The lower function doesn’t take any parameters. Let’s take an example to understand the conversion of string in lowercase − SCHOOL ----------- school UnIvErSiTy ----------- university Syntax ord() The ord() is a predefined function used in Python ...

While creating plots using Matplotlib which is a library of Python one common task is to add markers to indicate data points. Matplotlib provides a variety of marker styles which includes circles, triangles, squares, dots, and diamonds. These markers can be customized further with different sizes, colors, and edge sizes. In this article, we will discuss how to add markers to a graph plot and customize them in Matplotlib with Python. Matplotlib Matplotlib is a library that is mainly used for plotting graphs and plots for the Python programming language and NumPy, its extension for numerical mathematics. Tkinter, wxPython, ...
