Python Program to Format time in AM-PM format
In Python, we have some time built-in functions like strftime() and datetime.now() that can be used to find the time in AM/PM format. The format time in AM/PM format uses various applications such as user interface, report & document, data visualization, and event scheduling. We will speak the time of AM when timing between midnight 11:59:00 to 12 noon. In the same way, we can say that the time difference between 12 noon to 11:59:00 midnight is called PM. The abbreviation AM/PM is used to indicate the exact time. Syntax The following syntax is used in the example &miinus; strftime('%I:%M:%S ...
Read MorePython program to convert local time into GMT
When we are creating a web service that allows users all over the world to book events, we might use this program to convert each user's local time to GMT before putting it in our database. This would make comparing and displaying event times easier for users in different time zones comparing and displaying event times easier for users in different time zones. In Python, we have some time built-in functions like timezone(), localize(), now(), and astimezone() that can be used to convert the local time into GMT. The local time represents the current time whereas GMT is defined by ...
Read MorePython Program to convert the array of characters into the string
In Python, we have some built-in functions like join(), map(), reduce(), and len() that can be used to convert the array of characters into the string. The array of characters is defined by breaking each character from the string. Python has a predefined method join() to join all the characters to make the string. Another way to solve the program is by using list comprehension and the join() method. Let’s take an example to understand the conversion of an array of characters into a string − The character is ‘p’, ‘e’, and ‘n’: The string becomes a pen. The ...
Read MorePython Program to Print all the Pattern that Matches Given Pattern From a File
Finding lines in a file that match a particular pattern is a typical operation with many applications, such as log analysis, text processing, and data filtering. In this article, we will discuss the Python Program to Print all the Pattern that Matches Given Pattern From a File. To solve this problem, we will first create a pattern in a file to save it. Our task is to programmatically create the exact pattern that we see in the file. By applying some conditions it will check whether the pattern matches or not from a given file. Syntax with open("file_name.txt", "r") as file The ...
Read MorePython Program to demonstrate the time arithmetic
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 MorePython Program to Convert Milliseconds to Minutes and Seconds
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 ...
Read MorePython Program to Read and printing all files from a zip file
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 MorePython Program to Count number of lines present in the file
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 MorePython program to delete prefix substring from the given string
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 MorePython program to delete suffix from the given string
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 ...
