# Python Program To Print Pascal’s Triangle (2 Ways)

In this program, we will learn how to print Pascal’s Triangle using the Python programming language.

### What is Pascal’s Triangle?

In mathematics, It is a triangular array of the binomial coefficients. It is named after the French mathematician Blaise Pascal.

We will discuss two ways to code it.

• Using Factorial
• Without using Factorial

## Python Programming Code To Print Pascal’s Triangle

### Using Factorial

We have already discussed different ways to find the factorial of a number. So, you look up there to learn more about it.

### Code:-

```def fact(n):
res=1
for c in range(1,n+1):
res = res*c

return res

rows = int(input("Enter the number of rows : "))

for i in range(0, rows):
for j in range(1, rows-i):
print("  ", end="")

for k in range(0, i+1):
coff = int(fact(i)/(fact(k)*fact(i-k)))
print("  ", coff, end="")

print()```

### Ouput:-

```Enter the number of rows : 5
1
1   1
1   2   1
1   3   3   1
1   4   6   4   1
```

### Code:-

```rows = int(input("Enter the number of rows : "))
for i in range(0, rows):
coff = 1

for j in range(1, rows-i):
print("  ", end="")

for k in range(0, i+1):
print("  ", coff, end="")
coff = int(coff * (i - k) / (k + 1))

print()```

### Output:-

```Enter the number of rows : 8
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
```
