Problem Name: Python - Designer Door Mat

In this HackerRank Functions in PYTHON problem solution,

Mr. Vincent works in a door mat manufacturing company. One day, he designed a new door mat with the following specifications:

• Mat size must be NxM. (N is an odd natural number, and M is 3 times N.)
• The design should have 'WELCOME' written in the center.
• The design pattern should only use |, . and - characters.

## Code Examples

### #1 Code Example with Python Programming

Code - Python Programming


N, M = map(int, input().split())

carac = ".|."
fill = "-"
middle = N//2
fac = 1

for x in range(N):
if x < middle:
print((carac*fac).center(M, fill))
fac += 2
elif x > middle:
fac -= 2
print((carac*fac).center(M, fill))
else:
print("WELCOME".center(M, fill))
