How about some clues as to what you're trying to accomplish? This code
is surprisingly verbose, and probably totally wrong. Anyway, each time
you pop an item from the list, all the following ones change their
index. So presumably there weren't still 79 items in the list by the
time you had removed and shuffled a bunch of them. You don't indicate
how many times it went around the outer loop, but in any case, there
won't be enough values the last time around.
sorry for the confusion. i'm trying to get:
ROW1=1XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ROW2=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ROW3=XX11111X11XXXXX11XXXXXX1XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ROW4=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX0XXXXXXXXXX1XXXXXXXXXXXX111111XXXX
whereby it will group the last column in the data file into each row with 128
characters in reverse order. for eg: in data below and if i group it into 4
characters in a row in reverse order will be:
row1=XX11
row2=XXXX
row3=XXXX
row4=00XX
0 BC_4 SYSCLK_DN observe_only 1
1 BC_4 SYSCLK_DP observe_only 1
2 BC_4 QPI3_DRX_DN 19 input X
3 BC_4 QPI3_DRX_DP 19 input X
4 BC_4 QPI3_DRX_DN 18 input X
5 BC_4 QPI3_DRX_DP 18 input X
6 BC_4 QPI3_DRX_DN 17 input X
7 BC_4 QPI3_DRX_DP 17 input X
8 BC_4 QPI3_DRX_DN 16 input X
9 BC_4 QPI3_DRX_DP 16 input X
10 BC_4 QPI3_DRX_DN 15 input X
11 BC_4 QPI3_DRX_DP 15 input X
12 BC_4 QPI3_DRX_DN 14 input X
13 BC_4 QPI3_DRX_DP 14 input X
14 BC_4 QPI3_DRX_DN 13 input 0
15 BC_4 QPI3_DRX_DP 13 input 0
It still makes no sense to me.
If you need to reverse a string, use [::-1] idiom
For example,
a = "abcde"
print a[::-1]
will print edcba
Hope that helps in some way. But I don't understand what you're trying
to do, and the example above doesn't make it any clearer.
