I was googling for a way to reverse a string and I found this.
It works, but there was no explanation where I got if from. Can someone please be kind enough to explain it. Thanks.

You have to read up on the slicing operator in the Python Manual.
Generally you can slice a sequence with [start: end: step]
By default start=0, end=len(seq), step=1
step=-1 goes from the end to the beginning of the sequence, hence your reverse.
For some nice slicing examples see post #4 at;
