Hi:
How to replace with blank the single-character in column 21 of a pdb
file (in pdb numbering it is column 22). Attached is an incomplete
exercise with slices. I am unable to get real plain text with gmail.
Thanks for help

# Sample line
# Slice indexes cut to the left of the corrresponding item index
# 1 2 3 4 5 6
# 012345678901234567890123456789012345678901234567890123456789012345 ...
# ATOM 1 N LEU A 1 153.242 64.673 95.851 0.00 0.00 N
data = open('in.pdb', 'r')
outp = open('out.pdb', 'w')
for L in data:
if L[21] == 'A':
L = L[ ???
outp.write(L)
