# Python: Create all possible permutations from a given collection of distinct numbers

## Python Basic - 1: Exercise-12 with Solution

Write a Python program that generates a list of all possible permutations from a given collection of distinct numbers.

**Pictorial Presentation:**

**Sample Solution**:

**Python Code:**

```
def permute(nums):
result_perms = [[]]
for n in nums:
new_perms = []
for perm in result_perms:
for i in range(len(perm)+1):
new_perms.append(perm[:i] + [n] + perm[i:])
result_perms = new_perms
return result_perms
my_nums = [1,2,3]
print("Original Cofllection: ",my_nums)
print("Collection of distinct numbers:\n",permute(my_nums))
```

Sample Output:

Original Cofllection: [1, 2, 3] Collection of distinct numbers: [[3, 2, 1], [2, 3, 1], [2, 1, 3], [3, 1, 2], [1, 3, 2], [1, 2, 3]]
