Answer:
SELECT inventory_id, film_id, title, store_id, address_id
FROM Inventory.Inventory
JOIN Business.store ON Inventory.store_id = store.store_id
JOIN Business.rental ON rental.film_id = Inventory.film_id
JOIN film_text ON Inventory.film_id = film_text.film_id
WHERE COUNT(rental_id) = 0;
Explanation:
The JOIN clause is also used to query tables from two databases. The Inventory and the Business database are joined in the inventory and store table respectively. The Query also joins the inventory table and the film_text table to get the title or name of the film rented where the rental_id count is equal to zero.
Coaxial cable<span>, or </span>coax<span> (pronounced </span><span>/<span>ˈkoʊ.æks</span>/</span><span>), is a type of </span>cable<span> that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term </span>coaxial<span> comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician </span>Oliver Heaviside, who patented the design in 1880.[1]<span> Coaxial cable differs from other </span>shielded cable<span> used for carrying lower-frequency signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a </span>transmission line<span>.</span>

Explanation:
Answer:
#section 1
def maxTemp(filename):
import pathlib
f = pathlib.Path(filename)
f.exists()
if f.exists():
f = open(filename, "r")
#section 2
next(f)
res = [int(sub.split(',')[1]) for sub in f]
maxdata = (res[0])
for i in range(len(res)-1):
if maxdata < res[i]:
maxdata = res[i]
index = res.index(maxdata)
f.close()
#section 3
li = []
a = open(filename, "r")
for line in a:
line = line.strip()
li.append(line)
a.close()
return (li[index+1])
else:
return -1
print(maxTemp("new.csv"))
Explanation:
#section 1:
The function maxTemp is defined. We import pathlib in other to check if the file exists, if it does we carry on with opening the file and if it doesn't the program returns -1.
#section 2:
We start splitting the sub-lists from the second line i.e <em>next(f)</em>. For each line we take the second index element and convert it to an integer.
<em>res = [int(sub.split(',')[1]) for sub in f]
</em>
The maximum number is gotten by using the if statement to compare all elements in the list. The index of the maximum item in the list is collected.
the file is then closed.
#section 3 :
The file is re-opened and all the lines are striped and passed into a new list and the index recovered from section 2, is used to get the day with the highest temperature and the line is returned.
The execution speed of machine language is faster than the execution speed of other languages. Machine or assembly language will execute the fastest as compared to high-level languages. No other language can execute faster than Machine language since instructions are directed straight to the CPU. Other high-level languages often add some non-zero amount of overhead to the execution time, thus, causing some delay.
