Python: Hello World With Prime Numbers
Please note that this is simply for fun and learning purposes.
You can achieve the same results like this:
print("hello, world")
But this way is so much crazier.
>>> ''.join([chr(x) for x in [int(x,16) for x in [hex(2 * 2 * 5 * 7 * 37 * 149 * 5417 * 148781 * 51939996061871)[i:(i+2)] for i in range(25)][2::2]]])
hello, world
How in the world does this print "hello, world"?
Let’s break this down:
>>> hex(2 * 2 * 5 * 7 * 37 * 149 * 5417 * 148781 * 51939996061871)
'0x68656c6c6f2c20776f726c64'
We can store this hex string into a variable, h.
Notice that these two are the same expressions below are the same, and the second is easier to understand. We start at 2, and take every other element.
>>> range(25)[2::2]
range(2, 25, 2)
# 2, 4, 6, 8, 10, .. 24
Okay cool, now we’re creating a list of chunks of h, with each chunk being a 2
character substring.
>>> [h[i:(i+2)] for i in range(25)[2::2]]
['68', '65', '6c', '6c', '6f', '2c', '20', '77', '6f', '72', '6c', '64']
Let’s store this list into a variable str_lst.
>>> [int(x,16) for x in str_lst]
[104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
We converted our hex strings into integers using the int() function passing
the second parameter 16 to let it know that we’re working with base16 (hex).
Let’s store this list of numbers into a variable num_list.
Great, a bunch of numbers! Now, simply convert each number to it’s ASCII representation, resulting in the new list:
>>> [chr(x) for x in num_list]
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
Just about done! Simply join the list into a string.
>>> ''.join([chr(x) for x in num_list])
'hello, world'
