Here is how I would produce a list of 7 unique random integers with
values between 123 and 175. Lines starting with "py> " are code which I
have typed in the Python interactive interpreter. I don't type the py>
part, Python automatically shows that. The output then follows:
py> import random
py> random.sample(range(123, 176), 7)
[129, 151, 147, 137, 130, 153, 152]
Can you adjust that to do what you want?

This is how I would print a list of numbers with a header, separating
each number with a bunch of dots:
py> numbers = [2, 4, 8, 16]
py> print("This is a header")
This is a header
py> print(*numbers, sep="......")
2......4......8......16
Note the asterisk * in front of numbers. What happens if you leave the
asterisk out? What happens if you leave the asterisk in, but remove the
"sep=" part?

Here is how I would find the largest and smallest numbers from a list:
py> numbers = [17, 11, 3, 99, 100, 41]
py> min(numbers)
3
py> max(numbers)
100
And here is how I would remove a number from a list:
py> print(numbers) # Before
[17, 11, 3, 99, 100, 41]
py> numbers.remove(99)
py> print(numbers) # And after.
[17, 11, 3, 100, 41]
> Print the length of the list with the header “The length of the list

Here is how I would find out the length of the list:
py> len(numbers)
5
Does this help you solve the problem?
