# Python Program to print pattern of letter H

Hello everyone! Welcome back to programminginpython.com. I am continuing with this pattern programming series, here I will tell you how to print the pattern of the letter H. In the previous tutorials, I have shown you the patterns of letters A to G. Here it’s now time for Pattern H. You can check the complete series on letter patterns here.

#### Print Pattern H – Code Visualization

Python program to print the pattern of letter H

#### Approach:

• Read an input integer for asking the size of the letter using `input()`
• Check if the entered number is greater than 8,
• if yes, call the function `print_pattern()`
• else, show a message to enter a number which is greater or equal to 8
• print_pattern()
• here we only do two things, print star(`*`) and print space(` `), just writing conditions so the pattern of `*`‘s and ` `‘s will display the pattern H
• following are 3 conditions for printing *’s
We have 2 loops, an outer loop() for rows, and an inner loop for columns.
• ```# Outer for loop
for row in range(n):

# Inner for loop
for column in range(n):```
• Print first and last column
• `(column == 0 or column == n-1)`
• Print middle row
• `(row == n //2 )`
• print ` ` in remaining all cases.

#### Program:

# Python3 program to print alphabet pattern H

# *         *
# *         *
# *         *
# * * * * * *
# *         *
# *         *
# *         *

def print_pattern(n):
# Outer for loop for number of rows
for rows in range(n):

# Inner for loop columns
for columns in range(n):

# prints first and last column
if ((columns == 0 or columns == n-1) or
# prints middle row
(rows == n // 2)
):
print("*", end=" ")
else:
print(" ", end=" ")
print()

size = int(input("Enter size: \t"))

if size < 8:
print("Enter a size greater than 8")
else:
print_pattern(size)
