I''m hoping someone will be able to help me, cause Ihaven''t had success searching on the web so far... I have large chunksof text ( all in a long string) that are currently all in separatenotebook files. I want to use python to read these strings of text,THREE CHARACTERS AT A TIME. (I''m studying the genetic code you see, soI need to read and analyse each sequence one codon at a timeeffectively.) Does anyone have any idea of how to do this using python?I''m going to be optimistic and thank you for your help in advance!Samantha. 解决方案 nuttydevil <sj***@sussex.ac.uk> wrote: Hey everyone!

I''m going to be optimistic and thank you for your help in advance! Samantha.Since you''re reading from files, the "read" operation of file-likeobjects takes an argument specifying the number of characters to readfrom the stream e.g. f = file("stuff.txt") f.read(3)''car'' f.read(3)''act'' f.read()''erization''Would that be enough for what you need?In article <11*********************@g43g2000cwa.googlegroups. com>,"nuttydevil" <sj***@sussex.ac.uk> wrote: Hey everyone!
