Hello all, I fell off the python programming wagon for awhile and I am quite rusty. I a text file that looks like this
*a bunch of stuff above* O(-2)/O(0) 12.5731 0.7181 ----------------------------Distribution of species---------------------------- Log Log Log Species Molality Activity Molality Activity Gamma OH- 4.121e-06 3.489e-06 -5.385 -5.457 -0.072 H+ 1.437e-09 1.259e-09 -8.843 -8.900 -0.057 H2O 5.551e+01 9.994e-01 1.744 -0.000 0.000 C(4) 5.334e-03 HCO3- 4.517e-03 3.877e-03 -2.345 -2.411 -0.066 *stuff below* I wrote this program: import string import csv, sys import matplotlib.pyplot as plt import numpy as np filein = raw_input("What is the name of your file?") testreader = csv.reader(open(filein)) for row in testreader: print(row) The output looks like this: [] ['----------------------------Distribution of species----------------------------'] [] ['\t Log Log Log '] ['\tSpecies Molality Activity Molality Activity Gamma'] [] ['\tOH- 4.121e-06 3.489e-06 -5.385 -5.457 -0.072'] ['\tH+ 1.437e-09 1.259e-09 -8.843 -8.900 -0.057'] ['\tH2O 5.551e+01 9.994e-01 1.744 -0.000 0.000'] What I am interested in is the species column and the activity column. The eventual goal is do do a bunch of calculations on the activties and plot it up using matplotlib. How do ignore everything before and after the Distribution of species and then pull out the species and activties so I can perform calculations on them? Is csv the best for that or am I better off using split and dumping into a dictionary? I think I need to specify white space as the delimiter, is that correct? Thank you very much.
