#4
n=int(input('give the length of staircase'))
for i in range(1, n+1):
print((n-i)*' ' + i*'#')

How can i know i have to initialise the var=0 before starting loop for them.
Please solve my query

[govindkeshari]

for i in range(n):
x=" "*(n-1-i)
y="#"*(i+1)
print(x, y)
Output is correct but its showing error.

can you tell me what's wrong with my code it prints exactlly the same but it says wrong answer
for i in range(n):
print(" "*(n-(i+1)), "#"*(i+1) )

[madhumetha]

for i in range (1, n+1) can you explain this y we put n+1

[marioamatucci]

skill up - use gen :P
```

def staircase(i):
while True:
res = "#" * i
yield str.rjust(res, n)


if __name__ == "__main__":
n = int(input().strip())
res = (next(staircase(i)) for i in range(1, n + 1))
print("\n".join(res))

```
