In Python, we can easily create Pascal’s Triangle with a loop to create a multi-dimensional list for a given number of rows.

```
def pascalsTriangle(rows):
t = []
for i in range(rows):
t.append([])
t[i].append(1)
for j in range(1,i):
t[i].append(t[i-1][j-1]+t[i-1][j])
if i != 0:
t[i].append(1)
return t
print(pascalsTriangle(5))
#Output:
[[1], [1, 1], [1, 2, 1], [1, 3, 3, 1], [1, 4, 6, 4, 1]]
```

To print a generated Pascal’s Triangle, we can loop over the triangle and print the elements.

```
def pascalsTriangle(rows):
t = []
for i in range(rows):
t.append([])
t[i].append(1)
for j in range(1,i):
t[i].append(t[i-1][j-1]+t[i-1][j])
if i != 0:
t[i].append(1)
return t
def printTriangle(t):
printString = ""
for i in range(0,len(t)):
printString = " " * (len(t) - i)
for j in range(0,len(t[i])):
printString = printString + str(t[i][j]) + " "
print(printString)
printTriangle(pascalsTriangle(5))
#Output:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
```

Pascal’s Triangle is a very interesting construct from the field of mathematics. Pascal’s Triangle is a triangular array constructed from summing adjacent elements in preceding rows.

In Python, we can easily create Pascal’s Triangle for a given number of rows with a for loop that loops over the number of rows and sums the adjacent elements from the previous row.

We can easily define a function which will create a multi-dimensional list with each row of the triangle.

Below is an simple Python function which generates Pascal’s Triangle for a given number of rows.

```
def pascalsTriangle(rows):
t = []
for i in range(rows):
t.append([])
t[i].append(1)
for j in range(1,i):
t[i].append(t[i-1][j-1]+t[i-1][j])
if i != 0:
t[i].append(1)
return t
print(pascalsTriangle(5))
#Output:
[[1], [1, 1], [1, 2, 1], [1, 3, 3, 1], [1, 4, 6, 4, 1]]
```

## How to Print Pascal’s Triangle in Python

The example above only shows how to create the numbers in Pascal’s Triangle. We can use Python to print a created Pascal’s Triangle by looping over each row and printing the elements.

We can print Pascal’s Triangle in a triangle so you can easily visualize the pattern and beauty of the construct.

Below are two examples printing Pascal’s Triangle with 5 and 10 rows to the console in Python.

```
def pascalsTriangle(rows):
t = []
for i in range(rows):
t.append([])
t[i].append(1)
for j in range(1,i):
t[i].append(t[i-1][j-1]+t[i-1][j])
if i != 0:
t[i].append(1)
return t
def printTriangle(t):
printString = ""
for i in range(0,len(t)):
printString = " " * (len(t) - i)
for j in range(0,len(t[i])):
printString = printString + str(t[i][j]) + " "
print(printString)
printTriangle(pascalsTriangle(5))
print()
printTriangle(pascalsTriangle(10))
#Output:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1
1 7 21 35 35 21 7 1
1 8 28 56 70 56 28 8 1
1 9 36 84 126 126 84 36 9 1
```
