Pattern programs in python

Pattern programs in python

Patterns can be printed in python using simple for loops. The outer loop is used for handling the number of rows and the inner loop handles the number of columns.

Here are few patterns and the python program to print the pattern.

Pattern 1 :

Given a number, a simple pyramid pattern with n number of rows is created with the values as column number.

For n = 4, the following number pattern will be printed.

1

1 2

1 2 3

1 2 3 4

Code :

n = int(input("Enter a number : "))

for i in range(n+1):

for j in range(1, i+1):

print(j, end = " ")

print()

Sample input :

n = 5

Sample output :

1

1 2

1 2 3

1 2 3 4

1 2 3 4 5

Pattern 2 :

For n =4, the following pattern will be printed.

Code :

n = int(input("Enter a number : "))

for i in range(n, 0, -1):

for j in range(1, i+1):

print(j, end = " ")

print()

Code :

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

k = (2*n) - 2

for i in range(0, n):

for j in range(0, k):

print(end=" ")

k = k - 2

for m in range(0, i+1):

print("* ", end="")
