On each iteration, it prints the first digit from the first loop and all 7 from the reverse loop. How can I print not all digits but only the last (i.e first) digit...

Is this the kind of thing you're looking for?
for idx,i in enumerate(x): print i,"\t",x[-(idx+1)]
Do you mean like this?
num = list(str(1234567)) for i in range(len(num)): print num[i], '\t', num[-(i+1)]
Output is:
1 7 2 6 3 ... .
Here's a feeble attempt.

You can ....
Consider is that return inside blocks is scoped to a surrounding method, and absent a surrounding method, a LocalJumpError is raised.
In Ruby, return statements inside blocks are scoped to their enclosing method.
Into a block.

What you need to do is move the assignment inside the for loop and check the length of the array from inside the foreach loop ;-)

If possible use, declaring it inside the loop where it is used actually helps make it more readable.
Declaring it inside the loop won't cause any harm to the memory and performance.

To encode your while loop in that form, there needs.
For the inside of the while loop, and that block also uses compare and choose to set the value of x implementations of smalltalk-family languages work like that.

Your idea of extracting the long code fragments inside of the "if" blocks is on the right.
Procedure DoC() { //hundreds of lines of code }
Of course, it may be useful to do this inside substantial.

Var new_time = new Date(); var seconds_passed = new_time - old_time;
By the way, why don't you just use the built-in .sort() ( https://developer.mozilla.org/en/Core_JavaScript_1... .
Var old_time = new Date(); ...
The simplest method is to compare by Date.
