Hi i'm new in programming and in python and i have an assignment that i cant
complete. I have to Write a Python program to compute and print the first 200
prime numbers. The output must be formatted with a title and the prime
numbers must be printed in 5 properly aligned columns . I have used this code
so far :
numprimes = raw_input('Prime Numbers ')
count = 0
potentialprime = 2
def primetest(potentialprime):
divisor = 2
while divisor = potentialprime:
if potentialprime == 2:
return True
elif potentialprime % divisor == 0:
return False
break
while potentialprime % divisor != 0:
if potentialprime - divisor 1:
divisor += 1
else:
return True
There are several things wrong with this function, and it's
redundant enough that maybe none of them matter. I'd test it
carefully.
while count int(numprimes):
if primetest(potentialprime) == True:
print potentialprime
count += 1
potentialprime += 1
else:
potentialprime += 1
but i get the result in a single column . How can i get it in 5 rows? Can
someone help please
As has been pointed out, you can use a trailing comma to suppress
the implied newline for each print.
Then you can add it back in every five items by checking count.
But you have a bigger problem, lining up the columns. Try using
the string modulus operator, or 'format'.
