An immutable sequence cannot be added or removed elements from it.Similar to a tuple, which is an immutable sequence a range is also immutable. The Python class range represents a sequence of numbers.After each iteration, the value of the number is increased. The inner for loop starts from 1 to i + 1, where i is the row number.The outer for loop iterates from 1 to the total number of rows.number variable is initialized with value 1.Here, i is the row number and j is the value ranging from 0 to i.ħ 8 9 10 Source Code rows = int(input("Enter number of rows: ")) The second inner loop first finds the number to be printed using statement coef = coef * (i - j) // j and then prints it.The first inner loop prints the spaces.The outer loop iterates from 1 to rows + 1.In this example, we have used three for loops. The second inner for loop prints the first half of the pyramid (vertically cut), whereas the last inner for loop prints the other half.ġ 5 10 10 5 1 Source Code rows = int(input("Enter number of rows: ")).The first inner for loop prints the spaces required in each row.The outer for loop iterates from i = rows to i = 1.In this example, we have used a total of 4 for loops. The while loop prints the numbers where 2 * i - 1 gives the number of items in each row.The inner for loop prints the required spaces using formula (rows-i)+1, where rows is the total number of rows and i is the current row number.Here we use two counters count and count1 for printing the spaces and numbers respectively.The outer for loop iterates through each row.Like example 6, this example also makes use of two loops inside a for loop. This formula gives the number of stars for each row, where row is i.ĥ 6 7 8 9 8 7 6 5 Source Code rows = int(input("Enter number of rows: ")) ![]()
