Using python

Part 3c: Custom Number Range

Make a copy of Part B and update it so that the user can choose to examine a specific range of numbers for prime numbers. Here's a sample running of your program:

Start number: 5
End number: -5
Start and end must be positive

Start number: 5
End number: 3
End number must be greater than start number

Start number: 5
End number: 23

5
7
11
13
17
19
23

Part 3d: Tabular Formatting

Print the prime numbers that you find within the given range so that only 10 numbers print per line. Align the numbers so that they stack neatly on top of one another in all cases (i.e. the table should line up no matter what number range you are analyzing). Here's a sample running of the program:

Start number: 1
End number: 100
  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 

And here's another running:

Start number: 1
End number: 1000
   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  101  103  107  109  113
 127  131  137  139  149  151  157  163  167  173
 179  181  191  193  197  199  211  223  227  229
 233  239  241  251  257  263  269  271  277  281
 283  293  307  311  313  317  331  337  347  349
 353  359  367  373  379  383  389  397  401  409
 419  421  431  433  439  443  449  457  461  463

Answer 1

Please find the code below:::

1)

def checkPrimeNumber(a):
k=0
for i in range(2,a//2+1):
if(a%i==0):
k=k+1
if(k<=0):
return True
else:
return False
  
  
def printPrimeInRange():
while True:
start = int(input("Start number : "))
end = int(input("End number : "))
  
if(start<=0 or end<=0):
print("Start and end must be positive")
elif(end<start):
print("End number must be greater than start number")
else:
break
  
  
for num in range(start,end+1):
if checkPrimeNumber(num):
print(num)
  
printPrimeInRange()
  
  

updated

def checkPrimeNumber(a):
k=0
for i in range(2,a//2+1):
if(a%i==0):
k=k+1
if(k<=0):
return True
else:
return False
  
  
def printPrimeInRange():
while True:
start = int(input("Start number : "))
end = int(input("End number : "))
  
if(start<=0 or end<=0):
print("Start and end must be positive")
elif(end<start):
print("End number must be greater than start number")
else:
break
  
  
count = 0
for num in range(start,end+1):
if checkPrimeNumber(num):
count+=1
print("%4d"%num,end="")
if count%10==0:
print()
  
printPrimeInRange()
  
  

Answer 2

To create a Python program that allows the user to examine a specific range of numbers for prime numbers and prints the prime numbers in tabular format, we can use the following code:

pythonCopy codedef is_prime(num):    if num <= 1:        return False
    for i in range(2, int(num**0.5) + 1):        if num % i == 0:            return False
    return Truedef print_primes_in_range(start, end, items_per_line=10):
    primes = [num for num in range(start, end + 1) if is_prime(num)]    for i in range(0, len(primes), items_per_line):        print(" ".join("{:4}".format(prime) for prime in primes[i:i+items_per_line]))def main():    print("Enter the range of numbers to examine for prime numbers:")
    start = int(input("Start number: "))
    end = int(input("End number: "))    if start <= 0 or end <= 0:        print("Start and end must be positive.")    elif end <= start:        print("End number must be greater than start number.")    else:
        print_primes_in_range(start, end)if __name__ == "__main__":
    main()

When you run this program, it will prompt you to enter the range of numbers to examine for prime numbers. After entering the start and end numbers, it will print the prime numbers within that range in tabular format, with 10 numbers per line.

You can copy and paste this code into a Python file (e.g., prime_numbers.py) and run it using a Python interpreter. It will then prompt you to input the start and end numbers to examine for prime numbers and display the result in tabular format.
