Sure, here are the steps to complete your assignment:

1. **Open the File**: Use the built-in `open()` function to open the file. This function requires the name of the file you want to open as a string.

```python
file = open('filename.txt', 'r')
```

2. **Read the File**: Once the file is opened, you can read its contents using the `read()` method.

```python
content = file.read()
```

3. **Parse the File**: You can use the `re` module in Python to find all the numbers in the file. The `findall()` function will return all non-overlapping matches of pattern in string, as a list of strings.

```python
import re
numbers = re.findall('[0-9]+', content)
```

4. **Convert Strings to Integers**: The `findall()` function will return a list of strings. You can use a list comprehension to convert these strings to integers.

```python
numbers = [int(num) for num in numbers]
```

5. **Compute the Sum**: Now that you have a list of integers, you can use the built-in `sum()` function to compute the sum of the numbers.

```python
total = sum(numbers)
```

6. **Print the Sum**: Finally, print the sum of all numbers.

```python
print(total)
```

7. **Close the File**: It's a good practice to always close the file when you're done with it.

```python
file.close()
```

Remember to replace `'filename.txt'` with the name of your text file.
