What does it take to design a door-mat using Python?

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 X. ( is an odd natural number, and is times .)
• The design should have ‘WELCOME’ written in the center.
• The design pattern should only use |, . and - characters.

Let’s dive into the code for it!

# Enter your code here. Read input from STDIN. Print output to STDOUT

if __name__ == ‘__main__’:

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

assert ((5 < N < 101) and (15 < M < 303) and M == 3*N), “N should be greather than 5 and less than 101. M should be greater than 15 and less than 303.”

c1, strn = ‘-’, “.|.”

wel = “WELCOME”

n = N//2

count1 = 1

dec1 = 1

count2 = int((M-6)/3)

#Upper half

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

print((c1*int((M-(3*dec1))/2) + (strn*count1) + (c1*int((M-(3*dec1))/2))))

count1 += 2

dec1 += 2

#Middle Line

print((c1*int((M-7)/2)) + wel + (c1*int((M-7)/2)))

#Lower half

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

print((c1*int(i*3)) + (strn*count2) + (c1*int(3*i)))

count2 -= 2
