---------------------------+------------------------------------------------
I'm missing in Sage a function equivalent to "readdata" in Maple,
which reads a file with one object per line, and convert it to a
list of the given type. Here is a tentative implementation:
{{{
def readdata(f,typ):
fp = open(f,"r")
l = []
while true:
s = fp.readline()
if s == '':
break
l.append(typ(s))
fp.close()
return l
}}}
For example readdata("integers", ZZ) will read a file containing one
integer per line, and convert it to a list of integers. One could
also extend the function to read n objects per line.
If a similar function already exists in Sage, please forgive me.
The function name might be renamed to read_data.
