how to iteratively create a grid within a bigger grid in python
def grid_print(area, units):
print_Area = (area * area)
grid_rows = units + (units + 1) + 2
grid_cols = units + 2
if units % 2 == 0: # If grid entry is even (it will end up making
grid_rows += 1 # the square uneven, so increase number of rows by 1
# now grid is technically uneven
for i in range(print_Area):
for row in range(grid_rows): # for each item in number of items(rows)
for col in range(grid_cols): # for each item in number of items(columns)
if row == 0 or row == int(grid_rows/2) or row == grid_rows -1: # if item is beginning, middle or end
# -- Formatting beam structure -- #
if col == 0: # beginning, print '+' no '\n'
print('+', end='')
elif col == grid_cols -1: # end, print '+'
print('+')
elif int(grid_cols/2) == col: # middle:
if grid_rows % 2 == 0: # if grid is even, pad '+' with ' '
print(' + ', end='') # if grid is uneven, no padding
else: # print '+' no '\n'
print('+', end='')
elif col % 2 == 0: # if col item is an even number
print('-', end='') # print '-' with no '\n'
else: # else if col item is uneven item num
print(' ', end='') # print ' ' no '\n'
else:
# -- Formatting line structure -- #
if col == 0: # if column is at starting position 0
print('|', end='') # print '|' no '\n'
elif col == int(grid_cols/2): # if column is at middle pos
if units % 2 == 0: # print '|' no '\n'
print(' | ', end='') # (has padding if grid is even or not)
else:
print('|', end='')
elif col == grid_cols -1: # if column is at end position of grid
print("|") # print '|'
else:
print(' ', end='') # all other circumstances, print ' ' no '\n'
