import random
line=5
def pyramid(line):
for each in range(1,line+1):
yield ' '*int((each/(each+1)*line)
for i in range(1,each+1):
yield str(random.randint(1,9))

yield str('\n')

pyramid=pyramid(line)

print(' '.join(pyramid))

Answer 1

Parenthesis missmatch at line 5... it should be:
yield ''*int(each/(each+1)*line)
... or:
yield ''*int((each/(each+1))*line)

However, that will only fix the Python syntax error, and you will get output, but not the one you expect ;P
Unfortunally, I doesn't understood what's the logic of your pyramid should be ^^

Answer 2

Replace the space used for the join() method to better see what doesn't work as expected:

print('.'.join(pyramid))

You'll see that you add a character at start of each line appart the first one, so you can fix it by:

print(' '+' '.join(pyramid))

Answer 3

I am sorry for my mistake 🙈

do you know why the first line of output is wrong ?
