Python: split and select the best one for undefined number of entries -


sorry if question silly... looking trick in python allow splitting line , selecting best value , corresponding source, actual number of entries unknown, can 1 100.

x = "32.1 (pdbbind), 50.1 (bdb), 83.0 (bmoad_4832)" in x.split(","):     b = []     if float(i.split()[0]) < float(b[0]):         b = i.split()[0]

i error "list index out of range".

the problem here:

b = [] if float(i.split()[0]) < float(b[0]):                               #^ b empty list, b[0] raise error

if understand problem right, concise solution be:

>>> max(x.split(","), key=lambda x: float(x.split()[0])) ' 83.0 (bmoad_4832)'
