# Python Program to print pattern of letter N

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 N. In the previous tutorials, I have shown you the patterns of letters A to M. Here it’s now time for Pattern N. You can check the complete series on letter patterns here.

#### Print Pattern N – Code Visualization

Python program to print the pattern of letter N

#### 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 that 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 N
• following are 2 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 column
```column == 0 ```

Print last column
```column == n - 1 ```

Print slanting line
```row == column ```

• print ` ` in remaining all cases.

#### Program:

```__author__ = 'Avinash'

# *             *
# * *           *
# *   *         *

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

def print_pattern(n):
for row in range(n):
for column in range(n):
# first column
if ((column == 0 or
# last column
column == n-1) or
# slanting line
row == column
):
print("*", end=" ")
else:
print(" ", end=" ")
print()

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

if size < 8:
print("Enter a value minumin of 8")
else:
print_pattern(size)
```
