There are multiple variations of generating triangle using numbers in Python. Let's look at the 2 simplest forms:
for i in range(5):
for j in range(i + 1):
print(j + 1, end="")
print("")This will give the output:
1 12 123 1234 12345
You can also print numbers continuously using:
start = 1
for i in range(5):
for j in range(i + 1):
print(start, end=" ")
start += 1
print("")This will give the output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
You can also print these numbers in reverse using:
start = 15
for i in range(5):
for j in range(i + 1):
print(start, end=" ")
start -= 1
print("")This will give the output:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
