How to count the amount of the printed numbers in an interval?

My code looks like this, it's almost done, just i need to count the amount of those printed numbers, and print that amount out with them.


start = int(input("Input the first number: "))
end = int(input("Input the last number: "))

 
for i in range(start,end):
  if i > 1:
    for j in range(2, i):
        if i % j==0 :
          break
    else:
      print(i)

Output:

2
3
5
7
11
13
17
19
23
29
31
37
41
43
47
53
59
61
67
71
73
79
83
89
97

The question is, that i want to print out that how many numbers are printed out there. Thanks for your answers!

Just create an incrementing variable and increment it every time you print something. Then at the end, print that variable.

count = 0

start = int(input("Input the first number: "))
end = int(input("Input the last number: "))
for i in range(start,end):
    if i > 1:
        for j in range(2, i):
            if i % j == 0 :
                break
        else:
            count += 1
            print(i)
            
print(f"Total numbers printed: {count}")

start = int(input("Input the first number: "))
end = int(input("Input the last number: "))

counter = 0  
  for i in range(start,end):
    if i > 1:
      for j in range(2, i):
          if i % j==0 :
            break
      else:
        print(i)
        counter = counter + 1
  print(counter)

If I understand this is what you are looking for? Everytime it prints, at the end you want to know how many times overall? So when it goes to print, use a counter to keep track then print it when the for loop finishes.
