python program to print pascal triangle

Pascal's Triangle is a mathematical concept that produces a triangular array of binomial coefficients. Each number in the triangle is the sum of the two numbers directly above it. The first few rows of Pascal's Triangle look like this:
In this tutorial, we will create a Python program to print Pascal's Triangle of a specified number of rows.
generate_pascals_triangle(rows): This function generates Pascal's Triangle up to the specified number of rows using the binomial coefficient formula.
print_pascals_triangle(triangle): This function prints the generated Pascal's Triangle in a visually appealing format, centering each number within its column.
main(): This is the main function where the user is prompted to enter the number of rows they want in Pascal's Triangle. It then calls the functions to generate and print the triangle.
The program uses the binomial coefficient formula to calculate the coefficients for each position in the triangle.
The map(str, row) converts each number in a row to a string for printing, and join is used to concatenate the elements of each row with spaces.
The if __name__ == "__main__": block ensures that the main() function is only executed if the script is run directly, not if it is imported as a module.
