I get output files from very old Fortran programs, which look like:

 0.81667E+00  -0.12650E+01  -0.69389E-03
 0.94381E+00  -0.11985E+01  -0.11502E+00
 0.96064E+00  -0.11333E+01  -0.17616E+00
 0.10202E+01  -0.12435E+01  -0.93917E-01
 0.10026E+01  -0.10904E+01  -0.15108E+00
 0.90516E+00  -0.11030E+01  -0.19139E+00
 0.98624E+00  -0.11598E+01  -0.22970E+00

Is it possible to read this in Python and convert the numbers to "normal" floats?
