Python String center() Method
Syntax
str.center(width[, fillchar])
width: Total width of the string.
fillchar: Filler character.
Problem Setter's code:
N,M = map(int,raw_input().split())
for i in xrange(1, N, 2):
print ( str('.|.')*i ).center(M, '-')
print str('WELCOME').center(M, '-')
for i in xrange(N-2, -1, -2):
print ( str('.|.')*i ).center(M, '-')
xrange name is not define -error
ReplyDeleteuse range instead of xrange
Deleteuse range instead of xrange and input instead of raw input
Deleten,m = map(int,input().split())
ReplyDeletepattern = [ ((".|.")*(2*i+1)).center(m,'-') for i in range(n//2) ]
print('\n'.join( pattern + ["WELCOME".center(m,'-')] + pattern[::-1] ))
N,M = map(int,input().split())
ReplyDeletec = ".|."
for i in range(N//2):
print((c*((i*2)+1)).center(M, '-'))
print(('WELCOME'.center(M,'-')))
for j in range(N//2):
print((c*((N-(j*2))-2)).center(M, '-'))
This is the solution I came up with
What's the meaning of
ReplyDelete"if__ name__=="__ main__":" in hackerrank
it represents main class just like void main in java
