How to invert the result of this for loop pyramid?
Question:
Our professor wants us to perform our previous problem of inverting the result of a pyramid of numbers, given a certain height, but now using for loops. I seem to be doing something wrong with my code.
What I have so far:
size = int(input("Height: "))
for num in range(size, 0, -1):
for num2 in range(1, num + 1):
print(num2, end=" ")
Output:
12345678
1234567
123456
12345
1234
123
12
1
Desired Output:
87654321
7654321
654321
54321
4321
321
21

Any help would be appreciated!
Answers:
you need to reverse your second for loop to achieve your the desired output.
Try like this:
size = int(input("Height: "))
for num in range(size, 0, -1):
for num2 in range(1, num + 1)[::-1]:
print(num2, end=" ")
print("n")
You just need a descending range within a descending range.
This should do it:
height = int(input('Height: '))
for i in range(height, 0, -1):
print(*map(str, range(i, 0, -1)))
Output:
Height: 8
8 7 6 5 4 3 2 1
7 6 5 4 3 2 1
6 5 4 3 2 1
5 4 3 2 1
4 3 2 1
3 2 1
2 1
