# Python: Create a list of random integers and select multiple items from the said list

## Python module: Exercise-8 with Solution

Write a Python program to create a list of random integers and randomly select multiple items from the said list.

Use random.sample

Sample Solution:

Python Code:

``````import random
print("Create a list of random integers:")
population = range(0, 100)
nums_list = random.sample(population, 10)
print(nums_list)
no_elements = 4
print("\nRandomly select",no_elements,"multiple items from the said list:")
result_elements = random.sample(nums_list, no_elements)
print(result_elements)
no_elements = 8
print("\nRandomly select",no_elements,"multiple items from the said list:")
result_elements = random.sample(nums_list, no_elements)
print(result_elements)
```
```

Sample Output:

```Create a list of random integers:
[46, 4, 45, 50, 43, 85, 74, 42, 99, 7]

Randomly select 4 multiple items from the said list:
[99, 45, 85, 50]

Randomly select 8 multiple items from the said list:
[46, 43, 74, 4, 45, 85, 99, 50]
```

## Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

```def tips_collect_dictionary(obj):
inv_obj = {}
for key, value in obj.items():
inv_obj.setdefault(value, list()).append(key)
return inv_obj
ages = {
"Owen": 25,
"Jhon": 25,
"Pepe": 15,
}
print(tips_collect_dictionary(ages))
```

Output:

```{25: ['Owen', 'Jhon'], 15: ['Pepe']}
```
