Question

I'm having trouble with problem 2 in problem set 1.so far i did this & getting an error::
from math import *
count = 0
i = 1
limitnum = raw_input('Enter the limit of the range')
for i in range(2,limitnum):
if limitnum/i == 0:
break;
else:
count= count+ log(i+1)
i = i + 1
print log(i)

Answer 1

You probably want to use % (modulo), not / (integer division)
For example: 13 / 5 = 2 and 13 % 5 = 3

Answer 2

Were you able to solve Problem 1 successfully? If so, please post the code. Problem 2 builds on Problem 1 and requires only a slight modification.

Answer 3

problem 1:

prime = 0
number = 1

while prime < 1000:
number = number + 1 # starting from 2

# testing if the number is prime or not
divisor = 2
numberIsPrime = True
while divisor*divisor <= number:
if number % divisor == 0:
numberIsPrime = False
break
divisor = divisor + 1

# found one?
if numberIsPrime:
prime = prime + 1

print number

Answer 4

problem 2 is giving an error:File "C:\Python25\ps1b.py", line 11, in <module>
for i in range(2,limitnum):
TypeError: range() integer end argument expected, got str.
still can't slove.

Answer 5

@maitre_kaio:thanx for highlighting the logical error,but i think it's giving me a syntax error.isn't it??i have post it above.
