In the realm of programming, ‘..’ represents a special operator known as the dot-dot operator, commonly used in conjunction with the range() function to create sequences of numbers. It signifies a consecutive range of values and acts as a convenient shorthand for defining number sequences.

In the realm of programming, ‘..’ represents a special operator known as the dot-dot operator, commonly used in conjunction with the range() function to create sequences of numbers. It signifies a consecutive range of values and acts as a convenient shorthand for defining number sequences. The general syntax for using the dot-dot operator in Python is: “`python range(start, stop, step) “` where: * start: The starting value of the sequence. * stop: The ending value of the sequence (excluded). * step: The increment value between each element in the sequence (optional; defaults to 1). The dot-dot operator (..) allows us to specify a range without explicitly listing all the values within it. For example: “`python my_range = range(1, 10) # Creates a range from 1 to 9 (since the stop value is exclusive) “` This code snippet creates a range object that contains the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. We can access individual elements of the range using square brackets ([]) or iterate over the entire range using a for loop: “`python # Accessing the first element print(my_range[0]) # Output: 1 # Iterating over the range for number in my_range: print(number) # Output: 1 2 3 4 5 6 7 8 9 “` The dot-dot operator can also be used with the negative step argument to create a range of numbers that decrement instead of increment. For example, the following code snippet creates a range from 10 down to 1: “`python my_range = range(10, 0, -1) # Creates a range from 10 to 1 (decrementing by 1) “` In summary, the dot-dot operator (..) is a versatile tool in Python that allows programmers to easily define sequences of numbers using the range() function. It simplifies the process of creating ranges and makes code more concise and readable… (dot-dot).. (dot-dot) Function: .. is a shorthand notation used in file paths to represent the parent directory of the current directory. Usage: .. is typically used in file paths to: * Move up one level in the directory hierarchy. * Refer to the parent directory of the current working directory. * Specify a path relative to the parent directory. Syntax: In a file path, .. is preceded by a forward slash (/) to indicate its absolute position. For example: “` /path/to/file.txt “` To access the parent directory of the above path, you can use: “` /path/to/.. “` This will navigate one level up in the directory hierarchy, resulting in the following path: “` /path/.. “` Examples: * To move up one level from the current working directory: “` cd .. “` * To refer to a file in the parent directory: “` mkdir Documents touch /Documents/my_file.txt cd Documents cat ../my_file.txt “` Benefits: Using .. simplifies file path navigation by reducing the need to specify the full path. It also makes file paths more portable, as the parent directory will remain the same regardless of the current working directory. Note: Remember that .. only refers to the immediate parent directory. To move up multiple levels, you can use .. multiple times. For example: “` /path/to/subfolder1/subfolder2/file.txt “` To move up two levels: “` /path/to/subfolder1/.. “`[News Article] [Date] [Dateline] [Lead Paragraph] [Write a brief and attention-grabbing summary of the main event or topic covered in the article.] [Body Paragraph 1] [Provide more detailed information about the event or topic, including key facts, figures, and quotes from relevant sources.] [Body Paragraph 2] [Explore the context and background of the event or topic, discussing its significance and potential implications.] [Body Paragraph 3] [Highlight any perspectives or reactions from individuals or organizations affected by or involved in the event or topic.] [Body Paragraph 4 (Optional)] [Provide additional context, analysis, or expert opinions to enhance the reader’s understanding of the subject matter.] [Concluding Paragraph] [Summarize the key points of the article and offer a brief outlook on what may happen next or what the ongoing consequences may be.] [Byline] [Name of the author or reporting team]
