Question
I have created a code, and I wonder that in each line, I need help in explaining in # comments which tells what is happening in that line of code.
![```python
import random
def middle(l):
if len(l) > 1:
l = l[1:-1]
return l
def main():
l = []
x = random.randint(1, 10)
for i in range(x):
l.append(i+1)
if len(l) == 1:
print("No change made to list.")
print("List Length =", x)
print(l)
print(middle(l))
main()
```
### Explanation:
- **Line 1:** The `random` module is imported to generate a random number.
- **Function `middle(l):`**
- **Lines 3-6:** This function takes a list `l` and checks if its length is greater than 1. If true, it returns a new list with the first and last elements removed.
- **Function `main():`**
- **Line 9:** Initializes an empty list `l`.
- **Line 10:** Generates a random integer `x` between 1 and 10.
- **Lines 12-13:** Fills the list `l` with integers from 1 to `x`.
- **Lines 14-15:** If the list has only one element, it prints "No change made to list."
- **Lines 16-18:** Prints the length of the list, the original list, and the modified list after applying the `middle()` function.
- **Line 20:** Calls the `main()` function to execute the program.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc71e03c3-7f81-463c-950e-c4fcee255c7b%2F4ba2cd91-cfc2-4ace-b7df-285b98d91f05%2Fvwvx28q_processed.png&w=3840&q=75)
