# Python - List Exercises

### Example 1

Python program to find unique numbers in a given list.

```L1 = [1, 9, 1, 6, 3, 4, 5, 1, 1, 2, 5, 6, 7, 8, 9, 2]
L2 = []
for x in L1:
if x not in L2:
L2.append(x)
print (L2)
```

It will produce the following output

```[1, 9, 6, 3, 4, 5, 2, 7, 8]
```

### Example 2

Python program to find sum of all numbers in a list.

```L1 = [1, 9, 1, 6, 3, 4]
ttl = 0
for x in L1:
ttl+=x
print ("Sum of all numbers Using loop:", ttl)
ttl = sum(L1)
print ("Sum of all numbers sum() function:", ttl)
```

It will produce the following output

```Sum of all numbers Using loop: 24
Sum of all numbers sum() function: 24
```

### Example 3

Python program to create a list of 5 random integers.

```import random
L1 = []
for i in range(5):
x = random.randint(0, 100)
L1.append(x)
print (L1)
```

It will produce the following output

```[77, 3, 20, 91, 85]
```
