"AttributeError" -Why am I getting this error while trying to slice the last word of every line in a file in Python

AttributeError: 'str' object has no attribute 'slice'

I'm trying to print the last word if every line in a file but while slicing the last word of each line (each line in file is a string) I'm getting the above mentione error.

This is the text inside my file: X-DSPAM-Confidence: 0.8475 X-DSPAM-Confidence: 0.6178 X-DSPAM-Confidence: 0.6961 X-DSPAM-Confidence: 0.7565

I'm trying to add the float values in the code and find its avg

Here's the code:

```
python code
```

    sum =0 
    count = 0
    myFile = open("C:/Users/Desktop/PDS/sample.txt", "r")
    for line in myFile:
        count += 1
        line = line.strip()
        if(line.startswith("X-DSPAM-Confidence")):
            line = line.slice(-1,-7)
            sum += line 
    myFile.close()
    print("Sum: ",sum)
    print("Avg: ", sum/count)

To extract the last word from each line in a file, you can use Python's string manipulation methods like split to split each line into words and then access the last word.

with open('your_file.txt', 'r') as file:
    for line in file:
        words = line.strip().split()
        if words:
            last_word = words[-1]
            print(last_word)
