Question

python: how would I format the grid below so that it is aligned correctly? as you see, I tried to center it but it is still not correct.

import random
row=random.randint(1,10)
col=random.randint(1,10)
for r in range(row):
for c in range(col):
if r %2==0 and c %2==0:
print(format('a','^3'),end=' ')
elif r %2!=0 and c %2!=0:
print(format("/x\\",'^3'),end=' ')
elif c%2!=0:
print(format('-','^3'),end='')
  
else:
print(format('s','^3'),end=' ')   
print() #go to next line

current Output is: (example if random function choses col=4 and row=3)

a - a -   
s /x\ s /x\   
a - a -   

Expected output: Rows Should be aligned so that each row and column line up together

import random
row=random.randint(1,10)
col=random.randint(1,10)
for r in range(row):
    for c in range(col):
        if r %2==0 and c %2==0:
            print('{:^3s}'.format('a'),end='')
        elif r %2!=0 and c %2!=0:
            print('{:^3s}'.format('/x\\'),end='')
        elif c%2!=0:
            print('{:^3s}'.format('-'),end='')
        else:
            print('{:^3s}'.format('s'),end='')
    print()
