Print Half Diamond Star Pattern

In this Python Program, we will be discussing about how to write a program to print Half Diamond Star Pattern. In this pattern, there are n rows with i numbers of time of iterations through all the rows and i+1 numbers of column are present for printing upper stars. Run another loop with i numbers of time of iterations through all the rows and num-1 numbers of column are present for printing lower stars. So, User have to enter a single value, that will be determine as a number of rows of the pattern. With the help of “Two Different Different Nested For Loop” , we will print the Half Diamond Star Pattern.

Python Program for Printing Half Diamond Star Pattern

Working:

Step 1. Start

Step 2. Take number of rows as input from the user and stored it into num.

Step 3. Run a loop ‘i’ number of times to iterate through all the rows which is Starting from i=0 to num.

Step 4. Run a nested loop inside the main loop for printing stars which is starting from j=0 to i+1.

Step 5. Move to the next line by printing a new line using print() function.

Step 6. Run another outer loop ‘i’ number of times to iterate through all the rows which is Starting from i=1 to num.

Step 7. Run a nested loop inside the main loop for printing stars which is starting from j=0 to num-1.

Step 8. Move to the next line by printing a new line using print() function.

Stop 9. Stop

Python Program:

num = int(input("Enter the Number: "))

for i in range(0, num):
    for j in range(0, i+1):
        print("*", end="")
    print()

for i in range(1, num):
    for j in range(0, num-i):
        print("*", end="")
    print()

    TRY THIS BRO, IT’S WAY EASIER:
    n = int(input(‘enter no.of rows: ‘))

    for i in range(1, n+1):
    if i<=(n+1)/2:
    print('*'*i)
    else:
    print('*'*(n+1-i))

    rows = int(input(“Enter the number of rows: “))
    for i in range(rows-1):
    for j in range(i+1):
    print(“*”, end=” “)
    print()
    for i in range(rows):
    for j in range(i,rows):
    print(“*”, end=” “)
    print()

    num = int(input(“enter number star pattern”))
    for i in range(1,num+1):
    print(“* ” * i )
    for j in range(1, num):
    print(“* ” * (num – i))

    for i in range(n,0,-1):
    why the range is taken as mentioned above? please explain

    n=int(input(“Enter the number: “))
