I want to make a table of alternating 1's and 0's using for statements and lists for a given number of rows and columns (similar to the code below). Any ideas as to how I would do this?
#fill elements in left and right columns with ones
ROWS = m
COLUMNS = n
table = []
for i in range(COLUMNS):
if i ==0 or i == (COLUMNS-1):
column = [1] * ROWS
else:
column = [0] * ROWS
table.append(column)
for i in range(ROWS):
for j in range(COLUMNS):
print(table[j][i], end=" ")
print()
Maybe you want something like this:
ROWS = 5
COLUMNS = 5
table = [[1 if i%2==0 else 0 for i in range(COLUMNS)] for j in range(ROWS)]
for row in table:
for cell in row:
print (cell, end=' ')
print()
1 0 1 0 1
1 0 1 0 1
1 0 1 0 1
1 0 1 0 1
1 0 1 0 1
OR maybe:
table = [[(i+j)%2 for i in range(COLUMNS)] for j in range(ROWS)]
0 1 0 1 0
1 0 1 0 1
0 1 0 1 0
1 0 1 0 1
0 1 0 1 0
