How to Use Python f-string, String Format, and String Template to Format String Output

1. Using f-string (formatted string literals). Python f-strings provide a concise and readable way to embed expressions inside string literals, using curly braces `{}`. def use_f_strings(): # Using f-strings language = “Python” rank = 1 print(f”{language} is number {rank}!”) name = “Alice” age = 30 formatted_string = f”Name: {name}, Age: {age}” print(formatted_string) if __name__ == […]

How to Read a File in Text and Binary Mode in Python

Python provides different modes for handling files, with text mode being the default option for readable or writable files. Text mode operates with Unicode strings, whereas binary mode, denoted by appending ‘b‘ to the file mode, deals with bytes. Let’s explore how to work with bytes and Unicode when reading and writing files in Python.
