[Tutor] Gamma distribution function

Hello All, OK. This time a less trivial question. Is there a function to enable us sample from a Poisson distribution? There is random.uniform, random.normalvariate(), random.expovariate()... Is there some kind of random.poisson()? Thank you, culpritNr1 -- View this message in context

Re: [Tutor] power of 2.718282

Thanks Marc and Kent and all. math.exp() is what I was looking for. culpritNr1 -- View this message in context: http://www.nabble.com/power-of-2.718282-tp21441385p21441787.html Sent from the Python - tutor mailing list archive at Nabble.com

[Tutor] power of 2.718282

call that computation millions of times. Anything more efficient than 2.718182**10 may be good. Thank you, culpritNr1 -- View this message in context: http://www.nabble.com/power-of-2.718282-tp21441385p21441385.html Sent from the Python - tutor mailing list archive at Nabble.com

Re: [Tutor] casting string to integer in a list of lists

Thanks Daniel, That is EXACTLY what I was looking for. Actually, int() does not really work but this does: [ [line[0], eval(line[1]), eval(line[2])] + line[3:] for line in LoL] Again, thanks. culpritNr1 Daniel Sarmiento-2 wrote: > > I am not an expert and don't know

Re: [Tutor] casting string to integer in a list of lists

to python, my question was if there was an ELEGANT way to do this casting, perhaps as a list comprehension operation. I wondered if the beauty of python could reach that far. I thank you all for your comments, culpritNr1 trias wrote: > > Hi Your, > > I work with genomic data

Hi All, Say I have this nice list of lists: LoL = [['chrX', '160944034', '160944035', 'gnfX.145.788', '63.60'], ['chrX', '161109992', '161109993', 'rs13484104', '63.60'], ['chrX', '161414112', '161414113', 'rs13484105', '63.60'], ['chrX', '161544071', '1615
