PHP and Python Implement Project Euler 1, 2 questions

Recently began to learn python, so I took project Euler to practiced hand

Problem 1

If we list all the natural numbers below is multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

Run Result: 233168

PHP Version:

/** * @desc Project Euler 1 * @Author Tina * @Date 2015-08-27 * * * $sum = 0;for ($i =0; $i <1000; $i + +) {    if (($i%3 = 0) | | ($i%5 = = 0)) {        $sum + = $i;    }} Echo $sum;

Python version:

sum = 0for i in range:    if ((i%3 = = 0) or (i%5 = = 0)):        sum + = IPrint sum

Problem 2

Each of the new term in the Fibonacci sequence was generated by adding the previous. By starting with 1 and 2, the first terms would be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values does not exceed four million, find the sum of the Even-value D terms.

Run Result: 4613732

PHP Version:

/** * @desc: Project Euler 2 * @Author: Tina  * @Date: 2015-08-27 */$fab 1 = 1; $fab 2 = 1; $sum = 0;do{    $fab = $fab 1+ $fab 2;    $fab 1 = $fab 2;    $fab 2 = $fab;    if ($fab%2 = = 0) {        $sum + = $fab;    }} while ($fab < 4000000); Echo $sum;

Python version:

FAB1 = 1FAB2 = 1sum = 0while True:    fab = fab1+fab2    fab1 = fab2    fab2 = Fab    if (fab%2 = = 0):        sum + = fab< C5/>if (Fab > 4000000): Breakprint sum

In fact, the feeling is basically the same ... But read some Python introduction, feel very powerful, what list, dictionary, collection data type, incredibly can also handle complex numbers!! Very much looking forward to Ah! (PS: It seems that the invention of Python is a mathematical origin of the Daniel, no wonder Luo!) ）
