Python Intermediate Generators question:

Question

The task is to to take two inputs which have to be numbers and output a list of all primenumber in the given range. For some reason I am not able to determine Test 4 fails, while 1 - 3 succeed.

Here is what I've got so far:

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):
Mylist=[]
for i in range (a,b+1):
if isPrime(i) == True:
Mylist.append(i)
print(Mylist)

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

primeGenerator(f, t)

Answer 1

why last return True? in isPrime()?

Answer 2

u can try this

lower = int(input("Enter lower range: "))
upper = int(input("Enter upper range: "))

for num in range(lower,upper + 1):
if num > 1:
for i in range(2,num):
if (num % i) == 0:
break
else:
print(num)

Answer 3

Because it is a prime number if the if-clause does not retrun a false.

BTW: The isPrime Function was given a part of the task, so I did not write this myself.

Answer 4

does anyone solved this case?
thxs :-)

Answer 5

your error is on this line:

for i in range (a,b+1): <---- why did you put. " +1 "

the correct answer is without +1
