Any help would be greatly appreciated -- note: I need to use for loops for this program identical to the one in my first example.

Answer

You can code the `4`

cases as follows (Note that you need to use `' '`

instead of `''`

)

```
base=int(input("Enter the triangle size: "))
# Four loops for four different patterns
for i in range(1, base + 1):
print (('*' * i) + (' ' * (base - i)))
for i in range(1, base + 1)[::-1]:
print (('*' * i) + (' ' * (base - i)))
for i in range(1, base + 1):
print ((' ' * (base - i)) + ('*' * i))
for i in range(1, base + 1)[::-1]:
print ((' ' * (base - i)) + ('*' * i))
```
