Generate list of numbers and their negative counterparts in Python

Generate list of numbers and their negative counterparts in Python

You can generate a list of numbers and their negative counterparts in Python using a list comprehension. Here's how you can do it:

# Generate a list of numbers from 1 to 10 numbers = list(range(1, 11)) # Create a list of numbers and their negative counterparts using list comprehension numbers_with_negatives = [num for num in numbers + [-num for num in numbers]] # Print the result print(numbers_with_negatives)

In this code, range(1, 11) generates a list of numbers from 1 to 10 (inclusive). The list comprehension [num for num in numbers + [-num for num in numbers]] creates a new list containing the numbers from the original list numbers and their negative counterparts (e.g., if numbers contains [1, 2, 3], the resulting list will be [1, 2, 3, -1, -2, -3]). The list comprehension iterates over each number in the numbers list, and for each number, it appends both the original number and its negation to the new list.

The numbers_with_negatives list will contain the numbers from 1 to 10 and their corresponding negative counterparts in the same order.

Examples

  1. "Python code to generate positive and negative numbers"

    Description: This Python code generates a list of positive numbers along with their corresponding negative counterparts using list comprehension.

    positive_numbers = list(range(1, 11)) # Generate positive numbers from 1 to 10 numbers_with_negatives = positive_numbers + [-num for num in positive_numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)

  2. "Python generate list of numbers and their negatives"

    Description: This Python code generates a list of numbers and appends their negative counterparts using a loop.

    numbers = list(range(1, 6)) # Generate numbers from 1 to 5 numbers_with_negatives = [] for num in numbers: numbers_with_negatives.append(num) numbers_with_negatives.append(-num) print("Numbers with their negative counterparts:", numbers_with_negatives)

  3. "Python code for positive and negative number generation"

    Description: This Python code generates positive numbers and their corresponding negative counterparts using a list comprehension approach.

    numbers = list(range(1, 8)) # Generate numbers from 1 to 7 numbers_with_negatives = [num for num in numbers] + [-num for num in numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)

  4. "Python generate numbers with negatives in list"

    Description: This Python code generates a list of numbers and their negatives using the zip function and list comprehension.

    numbers = list(range(1, 6)) # Generate numbers from 1 to 5 numbers_with_negatives = [item for pair in zip(numbers, [-num for num in numbers]) for item in pair] print("Numbers with their negative counterparts:", numbers_with_negatives)

  5. "Python code to create list of numbers and their negatives"

    Description: This Python code generates a list of numbers and appends their negative counterparts using list comprehension and the extend method.

    numbers = list(range(1, 9)) # Generate numbers from 1 to 8 numbers_with_negatives = [] numbers_with_negatives.extend([num, -num] for num in numbers) flattened_list = [item for sublist in numbers_with_negatives for item in sublist] print("Numbers with their negative counterparts:", flattened_list)

  6. "Python generate positive and negative numbers list"

    Description: This Python code generates a list of positive numbers and their corresponding negative counterparts using list comprehension and concatenation.

    positive_numbers = list(range(1, 11)) # Generate positive numbers from 1 to 10 numbers_with_negatives = [num for num in positive_numbers] + [-num for num in positive_numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)

  7. "Python code for generating numbers with their negatives"

    Description: This Python code generates a list of numbers along with their negative counterparts using list comprehension and the append method.

    numbers = list(range(1, 7)) # Generate numbers from 1 to 6 numbers_with_negatives = [] [numbers_with_negatives.append(num) or numbers_with_negatives.append(-num) for num in numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)

  8. "Python generate list of numbers and their opposite"

    Description: This Python code generates a list of numbers and their opposite (negative) counterparts using a combination of list comprehension and the zip function.

    numbers = list(range(1, 9)) # Generate numbers from 1 to 8 numbers_with_negatives = [item for pair in zip(numbers, [-num for num in numbers]) for item in pair] print("Numbers with their negative counterparts:", numbers_with_negatives)

  9. "Python code to generate numbers along with negatives"

    Description: This Python code generates a list of numbers and their negatives using list comprehension and the append method.

    numbers = list(range(1, 11)) # Generate numbers from 1 to 10 numbers_with_negatives = [] [numbers_with_negatives.append(num) or numbers_with_negatives.append(-num) for num in numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)

  10. "Python generate list of numbers and their opposites"

    Description: This Python code generates a list of numbers and their opposite counterparts (negative numbers) using list comprehension.

    numbers = list(range(1, 11)) # Generate numbers from 1 to 10 numbers_with_negatives = [num for num in numbers] + [-num for num in numbers] print("Numbers with their negative counterparts:", numbers_with_negatives)
