 # Learn How To Make Python Pattern Programs With Examples 45 / 62 Blog from Python Fundamentals

Python programming language is quite easy to learn. The implementation of various libraries with the ease of syntax makes it stand out, one of the many reasons why it has become the most popular programming language in this decade. While the learning part is easy, the interviewers often seek your approach in building the logic for pattern programs. As tricky as it may sound, with python it is a piece of cake. In this article, we will learn about various pattern programs in python. The following topics are covered in this blog:

The pattern programs incorporate a lot of nested loops. So if you are not familiar with loops in python, make sure to check out the detailed tutorial on loops in python.

## Star Pattern Programs

Following are a few star pattern programs in python.

### Pyramid Pattern Program

```def pattern(n):
k = 2 * n - 2
for i in range(0,n):
for j in range(0,k):
print(end=" ")
k = k - 1
for j in range(0, i+1):
print("*", end=" ")
print("&#92r")

pattern(5)
```

Output: ### Reverse Pyramid Pattern Program

```def pattern(n):
k = 2*n -2
for i in range(n,-1,-1):
for j in range(k,0,-1):
print(end=" ")
k = k +1
for j in range(0, i+1):
print("*", end=" ")
print("&#92r")

pattern(5)
```

Output: ### Right Start Pattern Program

```def pattern(n):
for i in range(0, n):
for j in range(0, i + 1):
print("* ", end="")
print("&#92r")
for i in range(n, 0 , -1):
for j in range(0, i + 1):
print("* ", end="")
print("&#92r")

pattern(5)
```

Output: ### Left Start Pattern Program

```def pattern(n):
k = 2 * n - 2
for i in range(0, n-1):
for j in range(0, k):
print(end=" ")

for j in range(0, i + 1):
print("* ", end="")
print("&#92r")
k = -1
for i in range(n-1,-1,-1):
for j in range(k,-1,-1):
print(end=" ")
k = k + 2
for j in range(0, i + 1):
print("* ", end="")
print("&#92r")

pattern(5)
```

for j in range(0, i+1):
print("* " , end="")
print("&#92r")
k = 2 * n  - 2
for i in range(0 , n+1):
for j in range(0 , k):
print(end="")

```def pattern(n):
k = 2 * n - 2
for i in range(0, n):
for j in range(0, k):
print(end=" ")

print("* ", end="")
print("&#92r")

pattern(5)
```

```def pattern(n):
k = 2 * n - 2
for i in range(0, n):
for j in range(0 , k):
print(end=" ")
k = k - 1
for j in range(0 , i + 1 ):
print("* ", end="")
print("&#92r")
k = n - 2
for i in range(n , -1, -1):
for j in range(k , 0 , -1):
print(end=" ")
k = k + 1
for j in range(0 , i + 1):
print("* ", end="")
print("&#92r")

pattern(5)
```

Output: ### Diamond Star Pattern Program

```for i in range(5):
for j in range(5):
if i + j == 2 or i - j == 2 or i + j == 6 or j - i == 2:
print("*", end="")
else:
print(end=" ")
print()
```

Output: ## Number Pattern Programs

Here are a few programs with numeric patterns in java.

### Simple Numbers Program

```def pattern(n):
x = 0
for i in range(0 , n):
x += 1
for j in range(0, i + 1):
print(x , end=" ")
print("\r")
pattern(5)```

Output: ### Pascal’s Triangle Program

```def pascal(n):
for i in range(0, n):
for j in range(0, i + 1):
print(function(i, j)," ", end="")
print()

def function(n, k):
res = 1
if (k &gt; n - k):
k = n - k
for i in range(0, k):
res = res * (n - i)
res = res // (i + 1)

return res
