Here is the actual snippet of code
calc_depth = 8.1 # which is actually d unblockedFS = 13.4 # which is the indexed fs for line in file('21Ex6MV_tmr.dat'): d, fs1, fs2, fs3, fs4, fs5, fs6, fs7, fs8, fs9, fs10, fs11, fs12, fs13, fs14, fs15, fs16, fs17, fs18, fs19, fs20, fs21, fs22, fs23, fs24, fs25, fs26, fs27, fs28, fs29, fs30, fs31, fs32, fs33, fs34, fs35, fs36, fs37, fs38, fs39, fs40 = line.split() if float(d) == round(calc_depth): print float('fs' + str(int(round(unblockedFS)))) On 10/22/07, Alan Gauld <[EMAIL PROTECTED]> wrote: > > "Bryan Fodness" <[EMAIL PROTECTED]> wrote > > >I want to get a variable name dependent on another variable. > > Thats usually a bad idea, but... > > > I have tried, > > > > 'fs' + str(int(round(unblockedFS))) for fs13 > > I have no idea what you think this will do. > It gives a syntax error for me, which is what I expected. > > > and I get an invalid literal. > > Can you post real code and real error messages please? > > > If I code in the fs13, everything works.
