rotate matrix 90 degrees clockwise in python
#The program defines the square matrix 90 degrees clockwise direction.
m,n = map(int,input().split())
#m,n are the number of rows and columns.
#m = int(input('rows'))
l = []
for i in range(m):
x = list(map(int,input().split())) #for taking the rows a time and split it append to an empty list
l.append()
for i in range(m):
for j in range(m-1,-1,-1):
print(l[j][i],end=' ')
print(end='n')
