Part 4b: Addition Table

Next, add in a feature that asks the user if they want to identify 'Prime' numbers in their table. If the user elects to show prime numbers you can print a lowercase 'p' character after each prime number. Ensure that your table displays correctly, as described above.

Lowest number: 0
Highest number: 10
Would you like to identify Prime numbers in your table? (y/n): pikachu

Source COde:

def isPrime(n):
if(n<2):
return False
count=0
for i in range(2,n):
if(n%i==0):
count=count+1
break
if(count==0):
return True
else:
return False

lowest=int(input("Lowest number: "))
highest=int(input("Highest number: "))
choice=input("Would you like to identify Prime numbers in yout table?(y/n): ")
while (not(choice=='y')):
print("Invalid command,try again")
choice=input("Would you like to identify Prime numbers in yout table?(y/n): ")
  
print("+",end=" ")
for i in range(lowest,highest+1):
print(i,end=" ")

print()
print("-------------------------------------------------")
for i in range(lowest,highest+1):
print(i,"|",end=" ")
for j in range(lowest,highest+1):
if(isPrime(i+j)):
print((str(i+j)+'p'),end=" ")
else:
print(str(i+j),end=" ")
print()
