What is going on here?

Question

def isPrime(x):
if x < 2:
return False
elif x == 2:
return True
for n in range(2, x):
if x % n ==0:
return False
return True

def primeGenerator(a, b):
#your code goes here

f = int(input())
t = int(input())

print(list(primeGenerator(f, t)))

This is a problem from the python intermediate course. This line in the isPrime function is simply not explained: for n in range(2, x):
Why are there two numbers in the parentheses? What is going on in this line? n is being given the values of 2 and x? 2 then x? What is going on here?

Answer 1

The 'range' function can take up to 3 parameters: start, stop, and step.

'x' represents the stop in the code above.

Go to this page anytime you want to look up something like range and get the official description, which should be every time Sololearn introduces a new term.

Thank you so much for the help Keith. I can't even move on in the Python courser unless I understand this o pay for premium and have the answer spoonfed to me, it's so stupid. The stop start an step aspects of range were never explained in any caliber yet I need to understand them to finish the course 🙄

Answer 4

you can do a google search for things you don't understand. There are also plenty of other free tutorial sites, and there are books. Don't limit yourself on Sololearn's material.

I found that having the ability to look for answers is ultimately the bigger skill in learning to code than just memorizing the syntax and procedures.
