[Tutor] populating an array or using a dictionary

[Michael Langford]

Using the attached foo.dat and no linebreaks, what you're doing works
perfectly:
dic2 = {}
for line in file('foo.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()
    dic2[d] = (float(d), float(fs1), float(fs2), float(fs3),
                  float(fs4), float(fs5), float(fs6), float(fs7),
                  float(fs8), float(fs9),  float(fs10), float(fs11),
                  float(fs12), float(fs13), float(fs14), float(fs15),
                  float(fs16), float(fs17), float(fs18), float(fs19),
                  float(fs20), float(fs21), float(fs22), float(fs23),
                  float(fs24), float(fs25), float(fs26), float(fs27),
                  float(fs28), float(fs29), float(fs30), float(fs31),
                  float(fs32), float(fs33), float(fs34), float(fs35),
                  float(fs36), float(fs37), float(fs38), float(fs39),
                  float(fs40))
    print dic2

A neater way to do it looks like:

dic2 = {}
countOfVars=40
for line in file('foo.dat'):
    tokens = line.split()
    dval = tokens[0]
    ls = []
    for i in range(1,countOfVars+1):
        ls.append(float(tokens[i]))
    dic2[dval]=tuple(ls)
    print dic2
