[Biopython-dev] Use of depreciated string functions

[Bruce Southey]

Hi,
There are a number of files in Bio that import string. Many of these use 
depreciated functions (since Version 2) that are now string methods 
mainly  string.atof(), string.atoi()  and string.join(). The only real 
advantage of modifying these is to remove an import statement because 
these will not be removed until Python 3.

Perhaps the one exception is in HotRand.py: hex_digit = 
string.hexdigits.find( letter )

There are about 23 unique files that I identified via grep and many have 
more than one usage. While changing these is busy work, please let me 
know if you would like me to create patches for the next version of 
Biopython (ie 1.50) or just ignore this.

Thanks
Bruce
