## Method 1: Using sum() function

Python provides a function sum(). It accepts a sequence as argument, and returns the sum of all elements in the given sequence. We can pass a list of numbers to it as an argument, and it will return the sum of all numbers in that list. Let’s see an example,

```listOfNums = [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

# get sum of all numbers in the list
total = sum(listOfNums)

print(total)
```

Output :

```155
```

We got the sum of all numbers in the list.

## Method 2: Using for loop

Iterate over all the numbers in a list, and add them one by one. Let’s see an example,

```listOfNums = [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

total = 0

# get sum of all numbers in the list
for elem in listOfNums:
total = total + elem

print(total)
```

Output :

```155
```

We got the sum of all numbers in the list.

## Method 3: Using Generator expression

Iterate over all the numbers in a list using Generator expression. For each element, convert that to int, and pass them to sum() function. It will return the total of all number in the list. Let’s see an example,

```listOfNums = ['11', '12', 13, '14', 15, '16', 17, 18, 19, 20]

# get sum of all numbers in the list
total = sum(int(elem) for elem in listOfNums)

print(total)
```

Output :

```155
```

We got the sum of all numbers in the list.
