python - Invalid literal for float -

-

i having hardest time figuring out why scientific notation string passing float() function not work:

time = [] watbalr = [] area = np.empty([1,len(time)]) volume = np.empty([1,len(time)]) searchfile = open("c:\gradschool\research\caselton\hydrus2d3d\h3d2_profile1v3\balance.out", "r") line in searchfile:     if "time" in line:          time.append(re.sub("[^0-9.]", "", line))     elif "watbalr" in line:          watbalr.append(re.sub("[^0-9.]", "", line))     elif "area" in line:         area0 = re.sub("[^0-9.\+]", "", line)         print repr(area0[:-10])         area0 = float(area0[:-10].replace("'", ""))         area = numpy.append(area, area0)     elif "volume" in line:         volume0 = re.sub("[^0-9.\+]", "", line)         volume0 = float(volume0[:-10].replace("'", ""))         volume = numpy.append(volume, volume0) searchfile.close() --------------------------------------------------------------------------- valueerror                                traceback (most recent call last) <ipython-input-80-341de12bbc94> in <module>()      13         area0 = re.sub("[^0-9.\+]", "", line)      14         print repr(area0[:-10]) ---> 15         area0 = float(area0[:-10].replace("'", ""))      16         area = numpy.append(area, area0)      17     elif "volume" in line:     valueerror: invalid literal float(): 0.55077+03

however, following works:

float(0.55077+03) 3.55077

if put quotes around argument, same invalid literal comes up, tried remove quotes string , cannot seem so.

0.55077+03 0.55077 added 03. need e scientific notation:

0.55077e+03
